Whether or not children receive regular dental care is strongly associated with their parents' history of seeking dental care. A new report to appear in the journal Pediatrics, which has been released online, is the first to analyze the relationship between parents' and childrens' dental visits in a nationally representative sample.
"When parents don't see the dentist, their children are much less likely to see the dentist," says Inyang Isong, MD, MPH, of the MassGeneral Hospital for Children (MGHfC) Center for Child and Adolescent Health Policy, the study's lead author. "We also found that the children of parents who have put off their own dental care for financial reasons are more likely to have their care deferred due to cost as well. It looks like strategies to promote oral health should focus on the whole family."
The study's authors note that dental caries - tooth decay - is of one of the most prevalent childhood diseases and is particularly common among minority and low-income children. Previous studies have associated factors including insurance coverage, parents' income and education, and the availability of dental care in the local community with the likelihood that children will have regular dental visits.
Earlier investigations of the impact of parents' accessing dental care focused on particular demographic groups. In order to see whether associations from those studies applied more broadly, the current investigation analyzed data from the 2007 National Health Interview Survey and its Child Health Supplement, which are designed to collect basic health and demographic information, along with answers to questions on health topics of current interest, from a cross section of the U.S. population.
Survey responses including data regarding dental visits for both a child and parent in the same household was available for around 6,100 matched pairs. Among parents who reported seeing a dentist during the preceding year, 86 percent of children had also seen a dentist; but only 64 percent of the children of parents with no recent dental visit had seen a dentist during the previous 12 months. In addition, among parents who put off their own dental care because of financial considerations, 27 percent of their children also had dental care deferred. In contrast, only 3 percent of children whose parents had not put off their own care care had their dental care deferred.
"Even when children are covered by medical insurance, it appears that financial barriers are influencing parents' decisions about accessing dental care for their children," says Isong, a clincal fellow at MGHfC. "We're now in the process of looking at the impact of dental insurance - something not addressed by the NHIS - and other enabling resources on the relationship between parents' and children's receipt of dental care."
James Perrin, MD, of the MGHfC Center for Child and Adolescent Health Policy is senior author of the Pediatrics paper. Additional co-authors are Karen Kuhlthau, PhD, and Jonathan Winickoff, MD, MPH, MGHfC; Katharine Zuckerman, MD, MPH, Oregon Health and Science University; and Sowmya Rao, PhD, MGH Biostatistics Center.

Caution Advised Over Use Of New 'Dissolvable Tobacco' Products
The first study to analyze the complex ingredients in the new genre of dissolvable tobacco products has concluded that these pop-into-the-mouth replacements for cigarettes in places where smoking is banned have the potential to cause mouth diseases and other problems. The report appears in ACS's Journal of Agricultural and Food Chemistry.
John V. Goodpaster and colleagues point out that the first dissolvable tobacco products went on sale in 2009 in test markets in Indianapolis, Ind., Columbus, Ohio, and Portland, Ore. The products contain finely-ground tobacco and other ingredients processed into pellet, stick, and strip forms that are advertised as smoke and spit-free. Health officials are concerned about whether the products, which dissolve inside the mouth near the lips and gums, are in fact a safer alternative to cigarette smoking. Goodpaster and colleagues note the possibility that children may be accidentally poisoned by the nicotine in these products. "The packaging and design of the dissolvables may also appeal to children, and some dissolvables, such as Orbs, may be mistaken for candy," the report states.
The researchers' analysis found that the products contain mainly nicotine and a variety of flavoring ingredients, sweeteners, and binders. They note abundant scientific evidence about the potential adverse health effects of nicotine, including those involving the teeth and gums. Other ingredients in dissolvables have the potential to increase the risk of tooth decay and one, coumarin, has been banned as a flavoring agent in food because of its link to a risk of liver damage.
"The results presented here are the first to reveal the complexity of dissolvable tobacco products and may be used to assess potential health effects," said Goodpaster, noting that it is "therefore important to understand some of the potential toxicological effects of some of the ingredients of these products." Nicotine in particular, he noted, is a toxic substance linked to the development of oral cancers and gum disease.

Preventative Dental Care, Daily Toothbrushing Are Keys To Healthy Pet
When it comes to pet dental care, two Kansas State University veterinarians hope that owners remember an important message: Prevention is always better and often cheaper than treatment.
"Although prevention may be more effort for the owners, it has the best end result for their pets and often their pocketbook," said Marjory Artzer, a clinical assistant professor at the K-State Veterinary Medicine Teaching Hospital.
By the age of 3, about 80 percent of dogs and 70 percent of cats already have established periodontal disease, said Jennifer Akers, a clinical assistant professor at the Veterinary Medicine Teaching Hospital. Akers said preventative measures are key to identifying and stopping disease before it gets too bad.
Dogs often have more straightforward periodontal disease, ranging from mild cases of gingivitis that can be reversed with cleaning, to more advanced cases where dogs can lose teeth, Akers said. Cats more commonly suffer from issues with tooth resorption and inflammatory disease in their mouth.
Both conditions can be very painful for pets, but animals don't have to act as if they are pained for disease to exist in the mouth, according to the K-State veterinarians. Often pain comes on slowly, so the animal has time to adjust.
"A lot of times we only know it has been problematic for them after we've instituted therapy and they go back to feeling good and have a change in behavior for the better," Artzer said.
Some signs of dental problems include bad breath, bleeding from the gingiva, changes in eating behavior or pawing and rubbing faces.
Most dental pathology is best identified by a veterinarian, Artzer said, and to help identify any dental problems, owners should make sure their animals get an oral exam every year with their annual checkup.
To help prevent periodontal disease, owners should brush pets' teeth daily with a pet toothbrush and pet toothpaste. Do not use human toothpaste, Akers said, as it can be toxic to animals. Water-additives, dental chews and dental diets can also help prevent periodontal disease.
"For cats, vigilance in observing and trying to intercede as early in the disease process as possible helps to keep them more comfortable longer," Akers said. "Daily oral health care is important for preventing periodontal disease and also keeps the owners looking in the mouth on a routine basis for signs of problems."
Owners should not give dogs bones or other hard toys, as they are a common cause of tooth-breaking.
"With the best intention of providing something that owners may think is OK, it can have a very negative outcome," Artzer said. "If we provide pets with appropriate toys to chew, that is a better scenario."
Both veterinarians said owners should start dental care when pets are babies and easily trainable so that they become accustomed to daily toothbrushing. It is especially important for small breed dogs because they are most at risk for periodontal disease.
"Unfortunately, what we see is middle age older pets with really horrible disease in their mouths, and the owners, only in hindsight, wished that they had been doing something about it at a young age," Akers said.
But with preventative measures, owners can improve their animal's quality of life and prevent severe complications of periodontal disease, such as complicating factors for heart conditions, kidney problems or other dental diseases.
"Dental care can help pets live a long, happy pain-free life; but no dental care can often lead to very detrimental consequences that can be very painful for our pets and very detrimental for their long term survival," Akers said.

Raisins fight oral bacteria that cause cavities and gum disease
Compounds found in raisins fight bacteria in the mouth that cause cavities and gum disease, according to researchers at
the University of Illinois at Chicago.
"Our laboratory analyses showed that phytochemicals in this popular snack food suppressed the growth of oral bacteria
associated with caries and gum disease," said Christine Wu, professor and associate dean for research at the UIC College of
Dentistry and lead author of the study. Phytochemicals are compounds found in higher plants.
The data were presented today at the annual meeting of the American Society for Microbiology in Atlanta.
Wu and her co-workers performed routine chemical analyses to identify five phytochemicals in Thompson seedless raisins:
oleanolic acid, oleanolic aldehyde, betulin, betulinic acid and 5-(hydroxymethyl)-2-furfural.
Oleanolic acid, oleanolic aldehyde, and 5-(hydroxymethyl)-2-furfural inhibited the growth of two species of oral bacteria:
Streptococcus mutans, which causes cavities, and Porphyromonas gingivalis, which causes periodontal disease. The compounds
were effective against the bacteria at concentrations ranging from about 200 to 1,000 micrograms per milliliter.
Betulin and betulinic acid were less effective, requiring much higher concentrations for similar antimicrobial activity.
At a concentration of 31 micrograms per milliliter, oleanolic acid also blocked S. mutans adherence to surfaces. Adherence is
crucial for the bacteria to form dental plaque, the sticky biofilm that accumulates on teeth. After a sugary meal, these
bacteria release acids that erode the tooth enamel.
Wu said that the findings counter a longstanding public perception that raisins promote cavities.
"Raisins are perceived as sweet and sticky, and any food that contains sugar and is sticky is assumed to cause cavities," Wu
said. "But our study suggests the contrary. Phytochemicals in raisins may benefit oral health by fighting bacteria that cause
cavities and gum disease."
"Moreover, raisins contain mainly fructose and glucose, not sucrose, the main culprit in oral disease."
In an earlier unpublished study, Wu's collaborator Shahrbanoo Fadavi, a pediatric dentist at UIC, found that adding raisins
alone to bran cereal did not increase the acidity of dental plaque. Raisin bran cereal with added sugar, however, did raise
acidity levels.
"Foods that are sticky do not necessarily cause tooth decay. It is mainly the added sugar, the sucrose, that contributes to
the problem," Wu said.
The present investigation was funded by the California Raisin Marketing Board.
Wu's main collaborator in the study was A. Douglas Kinghorn, an adjunct professor in the UIC College of Pharmacy. Other UIC
faculty involved in the work were Baoning Su, in the College of Pharmacy, and Jose Rivero-Cruz and Min Zhu in the College of
Dentistry.
UIC ranks among the nation's top 50 universities in federal research funding and is Chicago's largest university with 25,000
students, 12,000 faculty and staff, 15 colleges and the state's major public medical center. A hallmark of the campus is the
Great Cities Commitment, through which UIC faculty, students and staff engage with community, corporate, foundation and
government partners in hundreds of programs to improve the quality of life in metropolitan areas around the world. For more

Award Fails To Recognise Challenges We Face Say Scottish Dentists
Dr Robert Kinloch, Chair of the Scottish Dental Practice Committee, has branded the announcement of a 0.9 per cent increase to item of service fees for independent contractor dentists in Scotland as a major disappointment that fails to recognise the significant challenges dentists are trying to overcome.
The Doctors' and Dentists' Review Body recommended a 1.44 per cent increase to the NHS dental fee scale, a recommendation intended to produce no uplift to dentists' pay. The Scottish Government has decided to abate the DDRB's recommendation on the fee scale increase, by assuming that dentists will be able to make a one per cent efficiency saving on their operating costs. This decision will have the effect of reducing the uplift to 0.9 per cent.
Commenting on the announcement, Dr Kinloch, said:
"Dentists in Scotland appreciate the difficult financial climate the nation faces, but this is a disappointing announcement that does nothing to solve the problems we face. General dental services here have been underfunded for some time. Sharply rising expenses, including those resulting from the introduction of new requirements for decontamination in practices, are increasing the strain.
"Dental practices are run as private businesses and already function extremely efficiently. The idea that one per cent efficiency savings can be found is simply unrealistic. This is a pay cut. If that's what the Scottish Government intended, it should have said so."
The BDA has requested an urgent meeting with the Scottish Government to discuss the modification of the fee scale resulting from the announcement.

Milestone Scientific Hosts First International Computer-Controlled Local Anesthetic Delivery (CCLAD) Summit
Milestone
Scientific Inc. (OTC Bulletin Board: MLSS), the recognized leader in
advanced injection technologies, reported that earlier this month the
Company hosted the First International Computer-Controlled Local Anesthetic
Delivery (CCLAD) Summit in New Orleans. The Summit welcomed a distinguished
panel of dental experts who gathered to discuss advancements in the
scientific and clinical practice communities toward the common goal of
advancing the art, science and knowledge of CCLAD in dentistry.
Joe Martin, Chief Executive Officer of Milestone, noted, "Through this
Summit, Milestone hoped to provide a forum for open and objective
discussion by a unique blend of academia, key opinion leaders and
practicing dentists. The in-depth discussion, debate and exchange of ideas
that occurred helped to provide Milestone with confirmation that the
STA(TM) System and the CompuDent(R) (formerly known as The WAND(R)) are
significant improvements over traditional injection techniques."
The two day Summit was chaired by noted dental anesthetic expert,
Stanley Malamed, DDS, Professor of Anesthesia and Medicine School of
Dentistry at the University of Southern California School of Dentistry. Dr.
Malamed is also a Diplomate of the American Dental Board of Anesthesiology,
as well as a recipient of the Heidebrink Award from the American Dental
Society of Anesthesiology and the Horace Wells Award from the International
Federation of Dental Anesthesia Societies. He has authored more than 100
scientific papers and 16 chapters in various medical and dental journals
and textbooks in the areas of physical evaluation, emergency medicine,
local anesthesia, sedation and general anesthesia. In addition, Dr. Malamed
is the author of three widely used textbooks, published by CV Mosby:
Handbook of Medical Emergencies in the Dental Office (5th edition 2000);
Handbook of Local Anesthesia (4th edition 1997); and Sedation - a guide to
patient management (4th edition 2001).
Summit presenting participants also included:
-- John Brescia, DDS, PC, President of John J. Brescia, DDS, PC, a private
dental practice in River Forest, Illinois;
-- Monika Daublaender, MD, DDS, Associate Professor of Oral Surgery at
Johannes Guttenberg University in Germany;
-- Martin Jablow, DMD, a partner in the firm of Dental Technology
Solutions and general dental practitioner in Woodbridge, New Jersey;
-- William Lieberman, DDS, a nationally recognized pediatric dentist
practicing in Red Bank, New Jersey;
-- Peter Loomer, DDS, PhD, Associate Professor of Clinical Periodontology
at the University of California at San Francisco School of Dentistry;
-- Alfred Reader, DDS, MS, Professor of Advanced Endodontics at Ohio State
University College of Dentistry;
-- Kenneth Reed, DMD, noted dental anesthesiologist and nationally
recognized lecturer on dental anesthesia;
-- John Yagiela, DDS, PhD, Professor of Anesthesiology, Diagnostic and
Surgical Sciences at UCLA School of Dentistry.
This highly productive and interactive forum has yielded a number of
exciting ideas on how Milestone can integrate the STA System not only into
dental school curricula, but also extend the message to the dental
community and patients, alike. Martin stated, "It was perhaps most
gratifying to confirm that academics and clinicians, alike, recognize the
potentially profound impact that Milestone's CCLAD technology is having on
the practice of dentistry."
In February of last year, Milestone introduced to market the STA
System, a patented CCLAD system that incorporates the "pressure force
feedback" elements of Milestone's patented CompuFlo(R) technology, thereby
allowing dentists to administer injections accurately and painlessly into
the periodontal ligament space, effectively anesthetizing a single tooth.
The STA System is also capable of performing all of the injections that can
be done with a conventional dental syringe, including the palatal-anterior
superior alveolar, anterior middle superior alveolar and inferior alveolar
nerve block. The STA System achieves all of these injections predictably
and reliably and additionally allows a new and novel interactive injection
technique to be performed called the STA-Intraligamentary injection that
identifies the correct location and provides an almost immediate onset of
profound anesthesia to a single tooth. Milestone received FDA 510(k)
Pre-market Notification acceptance in August 2006 for the marketing and
sale of the highly anticipated STA System and has since named Henry Schein,
Inc. (Nasdaq: HSIC), the world's largest provider of healthcare products
and services to office-based practitioners in the combined North American
and European markets, as its exclusive distributor in the United States and
Canada.
"In light of the direction and recommendations to the dental community
we have derived from this Summit, Milestone looks forward to replicating
this event every year," concluded Martin.

dental school curricula, but also extend the message to the dental
community and patients, alike. Martin stated, "It was perhaps most
gratifying to confirm that academics and clinicians, alike, recognize the
potentially profound impact that Milestone's CCLAD technology is having on
the practice of dentistry."
In February of last year, Milestone introduced to market the STA
System, a patented CCLAD system that incorporates the "pressure force
feedback" elements of Milestone's patented CompuFlo(R) technology, thereby
allowing dentists to administer injections accurately and painlessly into
the periodontal ligament space, effectively anesthetizing a single tooth.
The STA System is also capable of performing all of the injections that can
be done with a conventional dental syringe, including the palatal-anterior
superior alveolar, anterior middle superior alveolar and inferior alveolar
nerve block. The STA System achieves all of these injections predictably
and reliably and additionally allows a new and novel interactive injection
technique to be performed called the STA-Intraligamentary injection that
identifies the correct location and provides an almost immediate onset of
profound anesthesia to a single tooth. Milestone received FDA 510(k)
Pre-market Notification acceptance in August 2006 for the marketing and
sale of the highly anticipated STA System and has since named Henry Schein,
Inc. (Nasdaq: HSIC), the world's largest provider of healthcare products
and services to office-based practitioners in the combined North American
and European markets, as its exclusive distributor in the United States and
Canada.
"In light of the direction and recommendations to the dental community
we have derived from this Summit, Milestone looks forward to replicating
this event every year," concluded Martin.

Nanotechnology Being Used To Improve Biocompatibility Of Human Prosthetics And Implants
As populations of the world age the current trend is that people are not slowing down in their later years. The desire for increased activity among the elderly also means increased demands on medical researchers to come up with better ways to keep them active. In the fields of implants and prosthetics calcium phosphate (CP) coatings on titanium alloy implants are proving their worth in orthopaedic and dental applications.
The most promising form of CP are hydroxyapatite (Ca10(PO4)6(OH)2, HA) coatings used to promote rapid bone remodelling on the titanium alloy implants. It is well known that the microstructure of these coatings significantly influences their mechanical properties and biocompatibility. Understanding the effect of nanostructures within a biocompatible coating could contribute greatly towards improving the effectiveness of these coatings.
In this study by Singaporean researchers, K.A. Khor, H. Li and P. Cheang, from Nanyang Technological University, the nanostructures and in vitro osteoblast behavior of individual CP splats were characterized. The splats were deposited using both plasma spraying and high velocity oxy-fuel (HVOF) onto polished Ti-6Al-4V substrates.
The results showed that the nanostructured HA splats are capable of enhancing the attachment and proliferation of the osteoblast cells. The study also revealed that the dissolution of the Ca/P-rich phases into the culture medium might promote the proliferation/differentiation of the osteoblast cells.

Researcher Identifies Stem Cells In Tendons That Regenerate Tissue
Athletes know that damage to a tendon can signal an end to their professional careers. But a consortium of scientists, led in part by USC School of Dentistry researcher Songtao Shi, has identified unique cells within the adult tendon that have stem-cell characteristics including the ability to proliferate and self-renew. The research team was able to isolate these cells and regenerate tendon like tissue in the animal model. Their findings hold tremendous promise for the treatment of tendon injuries caused by overuse and trauma.
The results of their research will be published in the October 2007 issue of the journal Nature Medicine and will be available online at nature/nm on Sunday, September 9, 2007.
Tendons, the tough band of specialized tissues that connect bone to muscle, are comprised of strong collagen fibrils that transmit force allowing the body to move. Tendon injuries are a common clinical problem as damaged tendon tissue heals slowly and rarely regains the integrity or strength of a normal, undamaged tendon.
"Clinically, tendon injury is a difficult one to treat, not only for athletes but for patients who suffer from tendinopathy such as tendon rupture or ectopic ossification," Shi says. "This research demonstrates that we can use stem cells to repair tendons. We now know how to collect them from tissue and how to control their formation into tendon cells."
Prior to this research, little existed on the cellular makeup of tendons and their precursors. By looking at tendons at the molecular level, the research team identified a unique cell population termed tendon stem/progenitor cells (TSPCs) in both mice and adult humans that when guided by a certain molecular environment, form into tendon cells. The team included leading scientists from the National Institute of Dental and Craniofacial Research at the National Institutes of Health, Johns Hopkins University and the University of Maryland School of Medicine.
Songtao Shi, a researcher for USC's Center for Craniofacial Molecular Biology, a Division within the USC School of Dentistry, has published numerous studies on the role of stem cells in regeneration. He was part of an international research team that successfully generated tooth root and supporting periodontal ligaments to restore tooth function in the animal model. Earlier this year, his research was published in the journal Stem Cells after he and his team discovered that mesenchymal stem cells are capable of regenerating facial bone and skin tissue in the mouse and swine models.
Funding for the study came from the USC School of Dentistry and the National Institutes of Health.

CIGNA Launches New Dental Plans; Continues Emphasis On Prevention
A little toothache can pretty quickly turn into a big headache - not just for your mouth but for your wallet too. That's why CIGNA's new series of dental HMO plans places an even greater emphasis on affordability and promoting wellness by covering more preventive dental care services.
For example, under the new plans, up to four routine cleanings a year - two at no cost and two for a minimal copay -- are covered when recommended by the dentist. Children are covered for two fluoride treatments a year to help prevent tooth decay, one of the most common chronic infectious diseases among U.S. children1.
"If you have dental insurance, you might pay nothing or very little out of your pocket for a routine dental visit (cleaning, x-rays and exam), compared with an average of $150 or more if you don't have coverage," said Dr. Miles Hall, chief dental clinical director for CIGNA*. "If you need to have a cavity filled, on average the cost would be $115 or more without insurance compared to low or no cost with our dental HMO plan. Waiting too long to treat a small cavity could mean you'd pay many times more for more costly dental procedures, such as a root canal, and spend more time away from work and personal life to recover. The key message we're sending with the new plan designs is 'prevention matters, so don't wait.'"
Hall said CIGNA is also changing some aspects of plan rules to make it easier for people to schedule their preventive dental care. Under the new plans, which are available now, the company is doing away with the requirement that cleanings be done at least six months apart.
In addition, the new plans cover teeth whitening - the kind of gel bleaching with take-home trays that many dentists offer. The plans continue to include important preventive features such as no age limitation on sealants, no referrals needed for orthodontic care, no referrals needed for care by a network pediatric dentist for children under 7, and coverage for procedures to help detect oral cancer early.
According to Bebe Shuler-Mure, assistant vice president of product for CIGNA's dental products, CIGNA has been working to broaden the network of dentists who participate in the dental HMO plan and now has over 13,600 unique dentists who practice among over 43,500 office locations in the network, one of the largest dental HMO networks in the country. Individuals can locate an in-network dentist using the dental directory on cigna.
At a time when the affordability of coverage is a concern for both employees and employers, the new plans are offered with a range of benefit and copay options.
"CIGNA's new dental HMO plans have more options available than many other carriers, including standard plans, plans with and without orthodontia coverage, specialty dental care discount, and split copay plans where copays are lower for using a general dentist and higher for dental specialty care," said Shuler-Mure. "This array of options gives employers flexibility to continue to provide a dental plan, even if their benefits budgets are under strain due to the economic downturn. The plans are also available on what is known as a voluntary (employee-paid) basis, where employees can get the advantage of obtaining insurance at lower, group rates."
CIGNA is also using its diverse product capabilities to provide value-added services for people in its dental plans. CIGNA will offer identity theft resolution services free of charge for individuals covered under the new series of dental HMO plans. Someone who falls victim to identify theft can be guided through the steps to recovery by an identify theft expert, 24 hours a day, 7 days a week, at no charge.
*Estimated costs without dental coverage may vary based on location and dentists' actual charges. These estimated costs are based on charges submitted to CIGNA as of February, 2009.

The Dentist Drill May Become A Thing Of The Past Thanks To New Treatment Using Ramon Spectroscopy Being Developed At Kings College London
A new technology that spots tooth decay almost as soon as it's begun promises to reduce the need for drilling and filling, writes Patrick Walter in SCI's Chemistry & Industry (C&I) magazine.
Drilling is one of the top dental phobias and puts thousands of people off visiting their dentist every year.
The new technology, which may be available in dental surgeries in five years from now, is based on Raman spectroscopy most commonly used to distinguish between different chemicals by identifying each molecule's unique fingerprint. It detects decay simply and painlessly by pointing a tiny optical fibre at the tooth to check on its health.
A preliminary study at King's College London, where the technique is being developed, found that chemical changes in the tooth could be detected by analysing how light is scattered when a laser is fired at the tooth. Researchers were able to tell healthy teeth from carious teeth because bacteria, responsible for the decay, scatter light in a different way to healthy teeth. The results were presented at Microscience 2008.
Frances Downey, a PhD student working on developing the technique at King's College London, said: 'The earlier you spot decay the better as you can remineralise the area so there is no cavitation and therefore no need for a filling.'
Dr Frederic Festy, who is supervising the project, is planning a larger trial using more teeth samples and hopes to move onto human trials soon. The key to the technique is its simplicity, he explains.
Currently, decaying teeth are uncovered either by visual examination or the use of x-rays, but usually by then, the damage has been done and the decayed area must be drilled out. But Dr Steven Hogg, a microbiologist at Newcastle University's dental school, confirms that it is possible to repair teeth with a special mouthwash or fluoride varnish if dental decay is caught early enough.
The downside of developing the machines is the cost and the time it takes to do a scan - 30 seconds can be a long time for any patient to remain perfectly still.

Alternative To Antibiotics May Be More Effective And Less Harmful
Photodynamic therapy (PDT) may be an effective way to treat the bacteria associated with periodontal diseases, and could provide a better option than antibiotics or other mechanical methods for treating periodontal diseases, according to a new study published in the March issue of theJournal of Periodontology.
Researchers at S??o Paulo State University found that using PDT was an effective method to minimize destruction of periodontal tissue which can accompany treatment for periodontal diseases. In a rat population, PDT did minimal damage to periodontal tissues, in comparison to other techniques including scaling and root planing and antibiotic therapy.
"We found that PDT is significantly less invasive than other treatments for periodontal diseases," said study author Dr. Valdir Gouveia Garcia, from the Department of Periodontology at S??o Paulo State University. "It can provide improved dentin hypersensitivity, reduced inflammation of the tissues surrounding the teeth, and allows tissues to repair faster."
PDT may be an alternative to antibiotic treatment, which is becoming increasingly important as antibiotic resistance increases. PDT involves two stages; first, a light-sensitive drug is applied to the area. Second, a light or laser is shone on that area. When the light is combined with the drug, phototoxic reactions induce the destruction of bacterial cells. PDT was first approved by the Food and Drug Administration in 1999 to treat pre-cancerous skin lesions of the face or scalp.
"This is an exciting finding," said Preston D. Miller, Jr., DDS and President of the American Academy of Periodontology. "PDT may be an effective therapy for the treatment of periodontal diseases. While patients have many options for treating their periodontal diseases, PDT could prove to be a preferable alternative to antibiotic therapy. Unfortunately, long term antibiotic therapy not only decreases the drug's effectiveness, but also may lead to the development of drug resistant organisms. Our Academy supports future research to further define the application of PDT as a means to treat periodontal disease."

American Dental Education Association Applauds Passage Of Health Care Reform Legislation
Two years ago, the American Dental Education Association (ADEA) entered the national debate on reforming the U.S. health care system. The cornerstone of ADEA's position, as approved by the ADEA House of Delegates in March 2009, was that any comprehensive health care reform proposal should provide universal coverage to all Americans and access to high-quality, cost-effective oral health care services.
On March 21, the U.S. House of Representatives approved health care reform legislation (H.R. 3590 and H.R. 4872) that will effect significant change in our health care system. "The legislation extends coverage to nearly all U.S. citizens, includes important provisions related to improving their oral health, addresses key issues of importance to academic dental institutions, and is entirely compatible with the Guiding Principles for Health Care Reform adopted by the ADEA House of Delegates," said Sandra C. Andrieu, Ph.D., ADEA President.
The American Dental Education Association is pleased with the outcome of the lengthy congressional debate and applauds the efforts of the House of Representatives and the Obama Administration in passing this historic legislation. The U.S. Senate should quickly pass the reconciliation bill, H.R. 4872, to conclude the health care reform legislative process.
Containing significant provisions for which ADEA has been advocating, the health care reform legislation approved by the House of Representatives will:
- Require insurance plans to include pediatric oral health services for children up to 21 years of age
- Require an essential health benefits package to include ambulatory patient services, emergency services, hospitalization, maternity and newborn care, mental health and substance use disorders, prescription drugs, rehabilitative and habilitative services and devices, laboratory services, prevention and wellness services and chronic disease management, and pediatric services, including oral and vision care
- Expand Medicaid eligibility for adults and children
- Increase federal support to states to pay for expanded Medicaid coverage
- Extend the Children's Health Insurance Program for five years
- Establish an oral health prevention program and fund states to develop oral health leadership
- Enhance oral health data systems
- Improve the delivery of oral health
- Implement dental sealants, water fluoridation, and preventive programs
- Establish a five-year national public education campaign focused on oral health care prevention and education and targeted to certain populations, including children, the elderly, and pregnant women
- Award demonstration grants in consultation with professional oral health organizations to eligible entities to demonstrate the effectiveness of research-based dental caries disease management activities
- Authorize the Medicaid and CHIP Payment and Access Commission (MACPAC) to review payments for dental services in Medicaid and CHIP
- Establish a process for updating payments to dental health professionals
- Reaffirm that dentists will be members of the MACPAC
- Establish a separate dental section and funding line of $30 million for training in general, pediatric, and public health dentistry
- Increase eligibility for new grant programs in the Title VII Health Professions Programs to train dental and allied dental health professionals
- Make dental schools eligible for federal grants for predoctoral training, faculty development, dental faculty loan repayment, and academic administrative units (grants currently available only to medical schools)
- Modify current law to allow hospitals to count dental and medical resident time spent in didactic (scholarly) activities toward Indirect Medical Education (IME) costs in hospital settings and toward Direct Graduate Medical Education (D-GME) in non-hospital settings (dental school clinics)
- Extend the National Health Service Corps (NHSC) and increase funding for its scholarship and loan repayment program by $2.7 billion over five years
- Reauthorize the Indian Health Service (HIS) and allow for the election by Indian tribes and tribal organizations in a state to employ dental health aide therapists when authorized under state law
- Authorize grants to establish training programs for alternative dental health care providers to increase access to dental health care services in rural, tribal, and underserved communities
- Reauthorize the Centers of Excellence (COE) program (which develops a minority applicant pool to enhance recruitment, training, academic performance and other support for minorities interested in careers in health) and fund it at $50 million
- Increase funding from $37 million to $51 million over five years for Health Professions Training for Diversity, which provides scholarships for disadvantaged students who commit to work in medically underserved areas as primary care providers and expands loan repayments for individuals who will serve as faculty in eligible institutions
- Exempt dental coverage from the premium amounts subject to excise tax on high cost insurance plans
For two years, the American Dental Education Association has raised its voice in the halls of Congress and at the White House in support of systemic health care reform that includes essential oral health benefits for all Americans. The reform that has been set into motion is, ADEA believes, the beginning of creating such a system and fulfilling our vision.

Record Number Of Volunteers Provided Free Dental Care To Needy Children In Minnesota
The results are in and a record number of nearly 2,500 volunteer dental professionals throughout Minnesota provided their services for free to children whose families could otherwise not afford the care. The annual Give Kids a Smile outreach effort provided 5,200 needy children with free dental care.
"It was wonderful to see a record number of volunteers come forward in this tough economy to help children whose families are facing difficult times," said Dr. Lee Jess, president of the Minnesota Dental Association, whose practice is located in Grand Rapids. Give Kids a Smile is sponsored by the Minnesota Dental Association.
The free care was provided on two days in February when 533 dentists across the state opened their offices and clinics to provide completely free dental care to children whose families could not otherwise afford the care.
This year marks the 7th consecutive year the Minnesota Dental Association has sponsored Give Kids a Smile. Since its inception, the program has served 32,000 young children and the donated services top $10 million dollars in value.
Nationwide the American Dental Association reports that over 12,000 dentists participated in this year's event, reaching 466,000 underserved children. The value of donated dental care in 2009 is estimated to be over $30 million.
The Minnesota Dental Association is the voice of dentistry in Minnesota, representing 81% of practicing dentists. It is committed to the highest standards of oral health and access to care for all Minnesotans. You can learn more at mndental.

Psychological And Social Issues Associated With Tooth Loss
Are feelings of depression overwhelming you? Is your self-esteem an issue? Having problems advancing in life or your career? Maybe you feel nervous or self conscious in social settings? Do you avoid social settings all together? Check your smile; tooth loss could be the culprit and you're not alone. Nearly 20 million teeth are extracted each year leaving scores of people to deal with the psychological affects of a less than perfect smile. However, during the Academy of General Dentistry's (AGD) 56th Annual Meeting & Exhibits in Orlando, Fla., July 16-20, H. Asuman Kiyak, PhD, will address the psychological issues affecting people who must deal with the loss of a tooth, as well as explain how this loss can affect the quality of life.
In Dr. Kiyak's course, "Enhancing the Oral Health and Quality of Life for Partially Edentulous or Fully Edentulous Patients: The Importance of Communication," she will reveal the post traumatic effects a patient endures after the loss of a tooth and will also pinpoint ways a doctor can communicate with a patient to help them cope with and understand their options for restoring their smile.
"The major impact of tooth loss is on the appearance and social relations component of quality of life because people cannot change their appearance with missing teeth," says Dr. Kiyak.
In fact, recent results from a survey distributed to nearly 20,000 AGD members revealed that more than 86 percent of general dentists reported social embarrassment is one of the greatest problems associated with tooth loss and more than half of these patients avoid social interaction because of it.
Yet, Dr. Kiyak noted that there are ways that patients can learn how to cope with the loss of a tooth. Dr. Kiyak encourages patients to:
Weigh their options with the pros and cons for replacement teeth or even endodontic treatment to save a "hopeless" tooth.
Review videos or still photos of others who have lost teeth and their current teeth status with removable or implant-supported dentures.
Read testimonials of others who have undergone single, multiple, total tooth loss and replacement of these teeth with removable or implant-supported dentures, how they have coped with each stage and how they are functioning orally, systemically and psychologically with these dentures.
"A smile serves as an individual's most powerful tool," says AGD spokesperson Laura Murcko, DMD. "A great smile can make a great lasting impression, boost a person's self-esteem and confidence as well as improve their overall health."
Dr. Kiyak is one of more than 100 speakers who presented the latest developments in oral health and technology during the AGD's Annual Meeting & Exhibits. Dr. Kiyak's course was held on Thursday, July 17.
About the AGD
The AGD is a professional association of more than 35,000 general dentists dedicated to staying up-to-date in the profession through continuing education. Founded in 1952, the AGD has grown to become the world's second largest dental association, which is the only association that exclusively represents the needs and interests of general dentists.
More than 786,000 persons are employed directly in the field of dentistry. A general dentist is the primary care provider for patients of all ages and is responsible for the diagnosis, treatment, management, and overall coordination of the general dentist through financial support of scientific, educational services related to a patient's oral health.

Dental And Medical Associations Form Partnership To Provide Teaching Tools To Educators Worldwide
The American Dental Education Association (ADEA) and the Association of American Medical Colleges (AAMC) have formed a partnership that will allow the AAMC to expand its unique MedEdPORTAL teaching tools repository to include dental education resources. The collaboration represents the first time academic medicine and dentistry have come together to share teaching resources across universities and throughout the world. MedEdPORTAL - a collection of high-quality, peer-reviewed educational resources submitted by medical educators - will begin accepting submissions from dental professionals on April 15.
"The potential impact that the collaboration can have on medicine and dentistry is substantial," said ADEA President James Q. Swift, D.D.S. "It benefits not only our students and their learning environment, but also faculty who deserve recognition for their scholarship - and overall health care can only be advanced."
"We are very pleased to collaborate with ADEA to incorporate dental educational resources in MedEdPORTAL," said AAMC President and CEO Darrell G. Kirch, M.D. "Given the competing demands on faculty time and tight budgets, ready access to high-quality, peer-reviewed teaching materials from a trusted source will be a tremendous benefit to both medicine and dentistry."
Since its launch in 2006, the AAMC's MedEdPORTAL has attracted both national and international recognition as a source of free, high-quality educational resources and a place for educators to receive recognition for their scholarly work. The partnership between ADEA and AAMC enables a higher degree of collaboration and integration between medicine and dentistry. Allowing medical and dental faculty to benefit from one another's knowledge, expertise, and excellence improves medical and dental education and ultimately patient care.
MedEdPORTAL is a central repository of peer-reviewed resources, graphics, tutorials, lab manuals assessment instruments, and faculty development materials, as well as an inventory of virtual patient cases. This storehouse of knowledge and tools, contributed to by faculty and students throughout the world, is available free to other educators and learners, thereby diminishing the need to duplicate valuable and expensive-to-produce resources. While it's widely recognized that educators have long invested time and intellectual capital creating tools with which to teach, they do not always receive recognition for doing so. By submitting materials to MedEdPORTAL, they receive rigorous peer review and feedback. If the materials are accepted for publication in MedEdPORTAL, educators receive recognition for their scholarship, which may be used to support promotion and tenure decisions.

Could This Signal The End For Dental X-rays?
Dental x-rays could be a thing of the past thanks to a new knowledge transfer partnership between the University of Abertay Dundee and pioneering research firm IDMoS.
A team of scientists from the university's SIMBIOS (Scottish Informatics and Mathematics Biology and Statistics) Centre will use sophisticated CAT (Computerised Axial Tomography) scanning equipment to verify that the company's newly developed equipment for detecting dental cavities works.
Chair of the Environmental Sciences School, Professor Iain Young said: "IDMoS have developed a non-invasive method of checking teeth for cavities.
"That means dentists will soon be able to check patients for tooth decay without resorting to x-rays which can be harmful and are often uncomfortable.
"Our role will be to verify that this new technology works by using CAT scans to check sample teeth for cavities and decay."
His colleague Dr Dmitri Grinev added: "Knowledge transfer partnerships (KTPs) like this provide Government funding to help commercial businesses gain direct access to university knowledge and expertise.
"Abertay runs proportionately more KTPs with individual companies than any other university in Scotland and we've been involved in a lot of new discoveries and new techniques.
"This project is particularly exciting because it has such great potential to change the way we all think about visiting the dentist."

Medications Plus Dental Materials May Equal Infection For Diabetic Patients
People who live with
diabetes on a daily basis are usually instructed to eat right, maintain
regular physical activity, and if necessary, take medication. What many may
not know is that these medications that help control healthy insulin levels
may lead to unexpected events at the dentist's office. According to a study
in the November/December 2007 issue of General Dentistry, the AGD's
clinical, peer-reviewed journal, diabetic patients especially need to
communicate special needs to their dentists. This is due to harmful
interactions that could occur because of the materials and medications used
at dental appointments.
According to the study, more than 194 million people worldwide have
diabetes, and health officials estimate that this figure will double or
triple in less than 20 years. "It is imperative that diabetic patients
inform their dentist of their needs in order to anticipate medication
interactions and physical reactions to treatment," says Lee Shackelford,
DDS, FAGD, spokesperson for the AGD. "The doctor must know if the patient
is taking insulin, and has taken their daily dose of insulin, in order to
anticipate the length of the appointment."
It does not stop, however, with diabetic patients; providing dentists
with as much information as possible about current medications is essential
for everyone's oral health. "It is important that your dentist is aware of
all of the medications that you are taking, including prescription drugs,
over-the-counter medications, and herbal drugs as they may interact with
agents that your dentist may use for your dental treatment," advises lead
author of the study, James Little, DMD, MS.
"Talk with your dentist if you are concerned about how the medications
you are taking could affect your oral health," advises Dr. Shackelford.
"Open communication is the best way to ensure that your dentist gives you
the best treatment possible."
Steps diabetic patients can take to ensure optimal dental care:
-- Find a dentist who is aware of the needs of diabetic patients.
-- See the dentist on a regular basis and alert him or her of any
changes in health status and medications.
-- Inform the dentist of any sores, swellings, or areas of redness in
the mouth, as well as any painful areas in the mouth.
-- Eat a normal meal prior to the dental appointment, take all diabetic
medications on schedule, bringing a blood sugar monitoring device to the
appointment, and inform the dentist if symptoms associated with low blood
sugar are felt.
The AGD is a professional association of more than 35,000 general
dentists dedicated to staying up-to-date in the profession through
continuing education. Founded in 1952, the AGD has grown to become the
world's second largest dental association, which is the only association
that exclusively represents the needs and interests of general dentists.

OralLongevity (TM) Program Targets Oral Health Of Older Americans
The potential
associations between oral health and overall health, including heart
problems, diabetes and pneumonia make it even more important for older
adults to maintain good dental health for a lifetime.
According to a recent report from the Centers for Disease Control and
Prevention, more adults are keeping their natural teeth longer well beyond
the age of 65. But changes in physical and mental functions could hamper
some older adults from taking proper care of their teeth and gums,
increasing the risk of dental disease that could complicate other health
conditions.
OralLongevity (TM) initiative addresses oral health of older adults
To help older adults, GlaxoSmithKline (GSK) Consumer Healthcare, the
American Dental Association (ADA) and the ADA Foundation this week
introduced a new, unique initiative called OralLongevity (TM) that focuses
on improving and maintaining good oral health throughout life.
OralLongevity (TM) will provide older adults, their families,
caregivers and dental professionals with education and other free resources
to increase the awareness of and need for better oral health.
"OralLongevity (TM) is just the beginning of a major effort to help
serve the oral health care needs of this growing and important segment of
the U.S. population," says Dr. Kathleen Roth, ADA president. "We are very
pleased to be part of this initiative that will benefit so many older
adults, their family members and caregivers."
"The OralLongevity (TM) initiative is dedicated to helping oral health
care providers and consumers understand the unique problems facing older
patients, and to help find solutions that will enhance the oral health care
of this fast-growing population group," states Dr. Ronald Rupp, US

Dental problems can cause pain and suffering as well as difficulty in
speaking, chewing and swallowing. Older adults also can suffer from dry
mouth, resulting from certain medications used to treat other health
conditions. Complications associated with medical conditions can impact the
ability to maintain good oral health.
These conditions are manageable to help improve the quality of life,
and the OralLongevity (TM) resources provide daily care tips.
Dr. Richard Price, ADA consumer advisor and retired dentist, advises
consumers to speak with a dentist about their dental problems to maintain
good oral health.
"For example, dry mouth and sensitive teeth can be managed and relieved
through dental care, behavioral changes and over-the-counter products," he
explains.
"The dentist is a key part of your health care team to advise you on
individual oral health needs as you age," Dr. Price emphasizes.

associations between oral health and overall health, including heart
problems, diabetes and pneumonia make it even more important for older
adults to maintain good dental health for a lifetime.
According to a recent report from the Centers for Disease Control and
Prevention, more adults are keeping their natural teeth longer well beyond
the age of 65. But changes in physical and mental functions could hamper
some older adults from taking proper care of their teeth and gums,
increasing the risk of dental disease that could complicate other health
conditions.
OralLongevity (TM) initiative addresses oral health of older adults
To help older adults, GlaxoSmithKline (GSK) Consumer Healthcare, the
American Dental Association (ADA) and the ADA Foundation this week
introduced a new, unique initiative called OralLongevity (TM) that focuses
on improving and maintaining good oral health throughout life.
OralLongevity (TM) will provide older adults, their families,
caregivers and dental professionals with education and other free resources
to increase the awareness of and need for better oral health.
"OralLongevity (TM) is just the beginning of a major effort to help
serve the oral health care needs of this growing and important segment of
the U.S. population," says Dr. Kathleen Roth, ADA president. "We are very
pleased to be part of this initiative that will benefit so many older
adults, their family members and caregivers."
"The OralLongevity (TM) initiative is dedicated to helping oral health
care providers and consumers understand the unique problems facing older
patients, and to help find solutions that will enhance the oral health care
of this fast-growing population group," states Dr. Ronald Rupp, US
professional relations, GSK Consumer Healthcare.

Practical Strategy For Oral Cancer Management In Dental Practices Published, UK
The British Dental Association (BDA) has published a practical guide to help dental professionals combat the growing problem of oral cancer. It reiterates the importance of the early detection of the condition, stressing the improved chances of patient survival in cases where early diagnosis takes place. The proportion of patients with oral cancer who die is higher than for cervical, breast or prostate cancers, the guide points out. It also warns that some patients are beginning to take legal action against dentists alleging failure to detect the condition.
The BDA guide, Early detection and prevention of oral cancer: a management strategy for dental practice, offers practical advice on preventing, detecting and managing oral cancer. It addresses both the clinical aspects of the condition and the management of relationships with patients. It explains the risk factors for the disease, provides guidance on talking to patients about examinations and offers tips on medical history taking and record keeping. It also explores taboos around the practitioner's right to explore patients' lifestyle choices that can cause oral cancer, such as drinking, smoking and chewing tobacco, and offers advice on how to overcome them.
Professor Damien Walmsley, the BDA's Scientific Adviser, said:
"The magnitude of the problem of oral cancer in the UK is growing. While the treatment of many cancers is leading to an improvement in survival rates, the same cannot be said for oral cancer. Early detection is absolutely vital to addressing this situation.
"General dental practitioners and their teams are ideally placed to lead the fightback, but they face many practical difficulties including patient resistance to practitioners' advice on lifestyle factors. This publication provides in-depth guidance on overcoming those problems and involving the whole dental team in the effective prevention, detection and treatment of the disease."
BDA members can access the guide free of charge here.

Consultation Expected To Lead To Piloting Of New Dental Contracts In 2011, UK
Dentists' leaders in Northern Ireland have welcomed the launch of the long-awaited consultation on piloting new dental contract arrangements.
The Health and Social Care Board's consultation runs until 31 January, 2011. It is expected to lead to the piloting of general dental services, orthodontic and oral surgery pilots next year with new contracts being developed for 2013 pending successful evaluation.
While pleased that progress is being made, the British Dental Association in Northern Ireland believes that much hard work lies ahead before and during the pilot phase.
Peter Crooks, Chair of the BDA Northern Ireland Dental Practice Committee, said:
"The BDA has long argued that we need new arrangements for dental care in Northern Ireland.
"Practices need a sustainable future as businesses with a working environment for dentists and their teams which deliver the modern, preventive care our patients seek.
"The HSCB's consultation signals, I hope, progress towards that goal. Continued engagement with BDA Northern Ireland is the key to success. The Government needs to listen to the views of the profession and work with the BDA to ensure the future success of pilots."

Government Creates New Regulatory Body: Care Quality Commission, UK
This week the Department of Health announced the creation of the Care Quality Commission which will regulate health (including dentistry) and social care by merging the majority of the functions of the Commission for Social Care Inspection, the Healthcare Commission and the Mental Health Act Commission.
This is the Government's formal response to the November 2006 consultation document The future regulation of health and adult social care in England. The government received over 100 responses from interested organisations, including the BDA, to its consultation which ran from November 2006 to February 2007. The responses can be viewed
here.
A Bill will be introduced in the next session of Parliament (due to start on 6 November), accompanied by a partial impact assessment (including an equality impact assessment) analysing the costs and benefits of these proposals. Subject to the passage of this legislation, the new commission will be established in 2008.
It's envisaged that the new Care Quality Commission will be able to take rapid and appropriate action against any registered organisation, including dental practices, which puts patients or users of services at risk. The Commission will have the power to inspect, undertake investigations, issue warning notices, fine providers and even close down services.
The Department of Health says the Commission will be able to decide how and when to use the enforcement powers and will be completely independent of Government.
The detail and scope of how the regulatory body will affect dentists has yet to be worked out, including whether its remit will extend to dentists who provide treatment solely on a private basis.
This will be decided following discussions with the BDA and the GDC over the winter, according to a Department of Health spokesperson.

Dentists Often First To Spot Eating Disorders In Patients
Delta Dental of Illinois wants to call attention to the dangers surrounding eating disorders and the need for early intervention and treatment during National Eating Disorders Awareness Week -- Feb. 22 - 28. Eating disorders are a serious healthcare concern and can cause a variety of oral health complications.
As many as 35 million men, women and children suffer from eating disorders in the United States. Dentists are becoming the first line of defense when it comes to spotting eating disorders in patients, according to the Academy of General Dentistry.
An eating disorder is a complex compulsion to eat in a way which
disturbs physical, mental, and psychological health. The three most
common eating disorders are anorexia nervosa, bulimia nervosa and
binge eating disorder. The eating may be excessive (compulsive over
eating); restrictive; or may include normal eating punctuated with
episodes of purging(1) (such as self-induced vomiting, use of
laxatives, fasting, diuretics or diet pills(2)). The eating may
include cycles of binging and purging; or may encompass the ingesting
of non-foods(1) (such as dirt, clay or chalk).(3)
"A parent may not recognize a child is anorexic or bulimic, however, through a routine dental checkup, a dentist may spot the oral signs of the disease," said Dr. Katina Morelli, D.D.S., dental director for Delta Dental of Illinois. "Eating disorders have serious implications for oral health and overall health so when dentists see the symptoms of eating disorders we encourage our patients to seek help."
Bad breath, sensitive teeth and eroded tooth enamel are just a few of the signs that dentists use to determine whether a patient suffers from an eating disorder. Other signs include teeth that are worn and appear almost translucent, mouth sores, dry mouth, cracked lips, bleeding gums, and tender mouth, throat and salivary glands.(4) Any of these symptoms can alert a dentist to a potential eating disorder.
Eating disorders rob the body of minerals, vitamins, proteins and other nutrients needed for good health and may cause injury to teeth, muscles and major organs.(1) Stomach acids can damage teeth with repeated exposures during purging for those individuals with bulimia nervosa. For those individuals with anorexia nervosa, which is characterized by self-induced starvation, poor nutrition can affect oral health by increasing the risk for periodontal [gum] diseases.
According to the National Eating Disorders Association, studies have found up to 89 percent of bulimic patients have signs of tooth erosion, due to the effects of stomach acid.(5) Over time, this loss of tooth enamel can be considerable, and the teeth change color, shape and length.
"Delta Dental of Illinois supports providing appropriate referrals to counselors or clinics for people with signs and symptoms of eating disorders," said Dr. Morelli. "We encourage those with eating disorders, or those who are caring for individuals with eating disorders to seek care from a dental professional to restore a healthy mouth."

American Dental Association Petitions FDA To Classify, Regulate Tooth-Whitening Products
The American Dental Association (ADA) asked the U.S. Food and Drug Administration (FDA) to establish appropriate classifications for tooth-whitening chemicals.
Citing concern about the safety of whitening products that are often administered without the benefit of professional consultation or examination by a dentist, the Association said that the application of chemically based tooth whitening or bleaching agents can harm teeth, gums and other tissues in the mouth.
The ADA pointed out that such concerns have prompted many states to prevent application of tooth whitening products in non-dental settings.
"The tremendous expansion of products available directly to consumers and application of products in venues such as shopping malls, cruise ships, and salons is troubling since consumers have little or no assurance regarding the safety of product ingredients, dosesor the professional qualifications of individuals employed in these non-dental settings," said ADA President Dr. Ron Tankersley and Executive Director Dr. Kathleen O'Loughlin, in a letter to the agency.
"Application of whitening/bleaching materials is not risk-free and may not be appropriate for all dark or discolored teeth," they wrote.

Calif. Dental Hygienists Making Difference In The Health & Smiles Of California Children
To help fight an
epidemic of cavities and oral disease among the state's young children, the
California Dental Hygienists' Association (CDHA) is offering information
about how to effectively spot and prevent tooth decay, which plagues
millions of California schoolchildren.
During February's National Children's Oral Health Month, as well as
throughout the entire year, California dental hygienists play a vital role
in raising awareness about a serious and often misunderstood problem in
oral health. The profession also devotes significant volunteer time to
helping protect the state's children from a preventable disease.
"Dental caries -- also known as cavities -- is the most common
childhood disease and can lead to a wide range of other health and other
problems," said Susan McLearan, president of CDHA. "Yet, there are some
very simple ways we as a society can better prevent and attack this
disease."
A Serious Problem
The first step, according to CDHA, is to understand the serious nature
of the disease and then take steps to eliminate the risk factors that can
lead to cavities, especially in small children.
-- Parents should realize how important baby teeth are to speech,
nutrition and self esteem
-- Early childhood caries is a very serious form of cavities that can
destroy the teeth of preschool children and toddlers
-- The first signs of caries are white chalky or brown spots on the teeth,
usually starting at the gum line
-- This problem may be overlooked by parents until the pain becomes so
severe and the teeth so decayed that the only options for these kids is
to have their teeth taken out
Prevention Tips
Prevention must begin early. CDHA recommends that a child's first
dental evaluation should be within six months after the first primary tooth
appears or by the time a child is one year old.
Additionally, parents should:
-- Try to eliminate starchy and sugary foods
-- Reduce or avoid nighttime bottle-feeding for infants. Putting a child
to bed with a bottle or the prolonged use of a "sippy" cup can cause
cavities.
-- Prevent contact with a parent or care taker with untreated caries,
which can easily spread to a child through the sharing of a spoon, cup,
etc.
-- Ensure that fluoride varnish or sealants are given to children who have
already had one or more cavities because they are considered a high
risk for developing more.
-- Promote brushing of teeth on a regular basis. When a tooth first
appears or erupts, it should be wiped gently with a damp cloth or soft
brush; beginning around ages two or three, children can use fluoride
toothpaste with a brush.
-- Seek the advice of a dental hygienist, who can work with parents to
make recommendations on how to avoid this serious disease
-- Use products containing xylitol, a natural sugar substitute that helps
fight bacteria that causes tooth decay.
"California dental hygienists are unsung heroes in the fight against
cavities," said CDHA's McLearan, who noted that her members are a wealth of
information for the public and generously volunteer their time to offer
nutritional counseling, oral health education in the schools, fluoride
treatments, cleanings and student dental screenings.
"For California dental hygienists, protecting our children from oral
disease is a 12-month effort," said McLearan. "This month is just a good
time to emphasize the problem and solutions to parents about better
protecting their children."
The California Dental Hygienists' Association (CDHA) is the
authoritative voice of the state's dental hygiene profession. While
registered dental hygienists have worked in the state for nearly a century,
CDHA was established 20 years ago when two regional associations merged to
form a unified professional group. CDHA represents thousands of dental
hygienists throughout the state and is dedicated to expanding opportunities
for the profession and access to care for all Californians.

During February's National Children's Oral Health Month, as well as
throughout the entire year, California dental hygienists play a vital role
in raising awareness about a serious and often misunderstood problem in
oral health. The profession also devotes significant volunteer time to
helping protect the state's children from a preventable disease.
"Dental caries -- also known as cavities -- is the most common
childhood disease and can lead to a wide range of other health and other
problems," said Susan McLearan, president of CDHA. "Yet, there are some
very simple ways we as a society can better prevent and attack this
disease."
A Serious Problem
The first step, according to CDHA, is to understand the serious nature
of the disease and then take steps to eliminate the risk factors that can
lead to cavities, especially in small children.
-- Parents should realize how important baby teeth are to speech,
nutrition and self esteem
-- Early childhood caries is a very serious form of cavities that can
destroy the teeth of preschool children and toddlers
-- The first signs of caries are white chalky or brown spots on the teeth,
usually starting at the gum line
-- This problem may be overlooked by parents until the pain becomes so
severe and the teeth so decayed that the only options for these kids is
to have their teeth taken out
Prevention Tips
Prevention must begin early. CDHA recommends that a child's first
dental evaluation should be within six months after the first primary tooth
appears or by the time a child is one year old.
Additionally, parents should:
-- Try to eliminate starchy and sugary foods
-- Reduce or avoid nighttime bottle-feeding for infants. Putting a child
to bed with a bottle or the prolonged use of a "sippy" cup can cause
cavities.
-- Prevent contact with a parent or care taker with untreated caries,
which can easily spread to a child through the sharing of a spoon, cup,
etc.
-- Ensure that fluoride varnish or sealants are given to children who have
already had one or more cavities because they are considered a high
risk for developing more.
-- Promote brushing of teeth on a regular basis. When a tooth first
appears or erupts, it should be wiped gently with a damp cloth or soft
brush; beginning around ages two or three, children can use fluoride
toothpaste with a brush.
-- Seek the advice of a dental hygienist, who can work with parents to
make recommendations on how to avoid this serious disease
-- Use products containing xylitol, a natural sugar substitute that helps
fight bacteria that causes tooth decay.
"California dental hygienists are unsung heroes in the fight against
cavities," said CDHA's McLearan, who noted that her members are a wealth of
information for the public and generously volunteer their time to offer
nutritional counseling, oral health education in the schools, fluoride
treatments, cleanings and student dental screenings.
"For California dental hygienists, protecting our children from oral
disease is a 12-month effort," said McLearan. "This month is just a good
time to emphasize the problem and solutions to parents about better
protecting their children."
The California Dental Hygienists' Association (CDHA) is the
authoritative voice of the state's dental hygiene profession. While
registered dental hygienists have worked in the state for nearly a century,
CDHA was established 20 years ago when two regional associations merged to
form a unified professional group. CDHA represents thousands of dental
hygienists throughout the state and is dedicated to expanding opportunities
for the profession and access to care for all Californians.

MU Laser Lab Will Enable Researchers To Change The Face Of Medicine
Many people equate lasers with a sci-fi battle in a galaxy far, far away or, closer to home, with grocery store scanners and compact disc players. However, an ultra-fast, ultra-intense laser, or UUL, with laser pulse durations of one quadrillionth of a second, otherwise known as one femtosecond, could change cancer treatments, dentistry procedures, precision metal cutting, and joint implant surgeries.
"The femtosecond laser has now entered the era of applications. It used to be a novelty, a fantasy," said University of Missouri researcher Robert Tzou, the James C. Dowell professor and chairman of the department of Mechanical and Aerospace Engineering. "We are currently targeting the areas of life-science and bio-medicine."
What makes the femtosecond laser different from other lasers is its unique capacity to interact with its target without transferring heat to the area surrounding its mark. The intensity of the power gets the job done while the speed ensures heat does not spread. Results are clean cuts, strong welds and precision destruction of very small targets, such as cancer cells, with no injury to surrounding materials. Tzou hopes that the laser would essentially eliminate the need for harmful chemical therapy used in cancer treatments.
"If we have a way to use the lasers to kill cancer cells without even touching the surrounding healthy cells, that is a tremendous benefit to the patient," Tzou said. "Basically, the patient leaves the clinic immediately after treatment with no side effects or damage. The high precision and high efficiency of the UUL allows for immediate results."
Practical applications of this type of laser also include, but aren't limited to, the ability to create super-clean channels in a silicon chip. That process can allow doctors to analyze blood one cell at a time as cells flow through the channel. The laser can be used in surgery to make more precise incisions that heal faster and cause less collateral tissue damage. In dentistry, the laser can treat tooth decay without harming the rest of the tooth structure.
Associate Professor Yuwen Zhang and Professor Jinn-Kuen Chen recently received a grant from the National Science Foundation to use the laser to "sinter" metal powders - turn them into a solid, yet porous, mass using heat but without massive liquefaction - a process which can help improve the bond between joint implants and bone.
"With the laser, we can melt a very thin strip around titanium micro- and nanoparticles and ultimately control the porosity of the bridge connecting the bone and the alloy," Zhang said. "The procedure allows the particles to bond strongly, conforming to the two different surfaces."
Tzou said the installation of a new laser laboratory at MU will enable research teams to "aggressively pursue success at a national level." The femtosecond laser lab, components of which were installed in January, was made possible through a gift from engineering alumnus Bill Thompson and his wife Nancy. Tzou noted that the arrival of the lab at MU has initiated additional funding requests that will utilize the new femtosecond laser in research. Zhang, Chen and engineering professor Frank Feng also were the recipients of a United States Department of Defense grant to research possible military applications of the UUL.
Tzou said most research with femtosecond lasers, thus far, has focused on engineering materials such as metals and semiconductors. Because of the unique infrastructure at MU, where the college of engineering and the medical school are located on the same campus, Tzou has been able to attract faculty members who have renowned expertise in medicine and laser technology to collaborate.

Fees Announcement Is Major Climb-down, Says BDA, UK
Today's announcement of a dramatic reduction of the fees that many dental practices will pay for registration with the Care Quality Commission (CQC) is a major climb-down, the British Dental Association (BDA) has said. Providers with up to three practices will pay significantly lower fees than were proposed in CQC's consultation, with the cost for those with a single location reduced from ??1,500 to ??800 and the cost for those with two or three locations reduced from ??3,000 to ??1,600.
Dr Susie Sanderson, Chair of the BDA's Executive Board, said:
"We are pleased to see this climb-down on fee levels. Dentists across England have made their concerns on this issue clear. Many have taken part in the BDA's red-tape campaign, articulating anxieties about the destructive effect costly, superfluous bureaucracy has on their working lives. These concerns appear, partially at least, to have been taken on board.
"Although the fees for many dentists have been reduced, it is important to remember that practices additionally incur significant hidden costs in demonstrating their ongoing compliance with CQC's standards. Scarce time and money are being diverted away from patient care to satisfy the burden being imposed by this unnecessary extra bureaucracy."
The BDA remains unconvinced of the necessity of CQC's role in dentistry and is disappointed about the delay in making this announcement.
Dr John Milne, Chair of the BDA's General Dental Practice Committee, said:
"The late announcement of these fees, just days before the deadline for registration, is frustrating for General Dental Practitioners in England. Sadly, it is typical of the shambolic nature of the process that dentists have been, and are still being, subjected to. CQC's challenge now is to demonstrate that it is making a difference for patients in return for the fees paid by dentists and the taxes the public are being asked to contribute to it. Only by doing so can it hope to justify the inclusion of dentistry in its remit."

What to Do About Sensitive Teeth
Foods - hot, cold, sweet or sour - can cause pain in a sensitive tooth. Touch or even air can be bothersome, too.
Usually the pain stems from enamel erosion or gum recession. The April issue of Mayo Clinic Health Letter offers tips to
manage the problem:
Use a desensitizing toothpaste -- They contain compounds that help block sensation that might otherwise stimulate pain in the
tooth's nerve. Choose a product that displays the American Dental Association's Seal of Acceptance.
Avoid using whitening or tartar control toothpastes as they may increase sensitivity to hot or cold.
Brush properly -- Use a soft toothbrush and brush with short back-and-forth strokes and a gentle up-and-down motion. Brush
thoroughly, and floss daily.
See your dentist -- If you still have discomfort when brushing, flossing, chewing or drinking, you may need dental treatment.
Sometimes coating sensitive areas of affected teeth with a fluoride gel or special desensitizing agent helps. If the culprit
is tooth decay, a cracked tooth or worn filling, these should be treated.
Here is a highlight from the April issue of Mayo Clinic Health Letter. You may cite this publication as often as you wish.

Patients Could Be Storing Up Dental Problems For The Future, Health Body Warns - British Dental Association
Reacting to the Healthcare Commission's national survey of 69,000 people's experience of primary care services, (including access to dentists), published, Susie Sanderson, Chair of the British Dental Association's Executive Board, said:
"Today the Government has received yet another powerful message about the state of NHS dentistry.
"The concern highlighted by the Healthcare Commission is that real problems for patients could be being stored up for the future.
"It's vital that urgent action is taken to tackle the flaws in the current NHS arrangements for dentistry, recently criticised so emphatically by the Health Select Committee.
"We also need to start looking carefully about what is meant by access to an NHS dentist and recognising the importance of the continuity of care."
-- The BDA's submission of written evidence to the inquiry can be accessed here.
-- Further details of the inquiry into NHS Dental and Orthodontic Services are available here.
The British Dental Association (BDA) is the professional association for dentists in the UK. It represents over 23,000 dentists working in general practice, in community and hospital settings, in academia and research, and in the armed forces.

Pennsylvania Dental Association Cautions Patients: Don't Forgo Dental Visits Because Of The Economy
As the economy remains unsteady and Pennsylvanians continue to cut back their expenses, the Pennsylvania Dental Association (PDA) is stressing the need for people of all ages to keep up with their oral health care.
"The PDA understands how difficult it is for families and individuals to make ends meet in economic hard times, especially those facing job losses," said Dr. Thomas W. Gamba, president of PDA. "Trying to save a little money by postponing regular dental checkups could result in serious oral health problems that could cost thousands of dollars in the long run. Maintaining good oral health is the most cost-effective approach."
PDA has no statistics on whether more Pennsylvanians are avoiding dental checkups because of the economy. However, Gallup-Healthways recently released the results of a 2008 poll of more than 355,000 Americans. It indicates that 34 percent - or more than one-third - of Americans did not visit a dentist last year. Pennsylvania was close to the national average, at 32 percent. Dentists are concerned that 2009's numbers, which will reflect the economy's impact, will result in even more patients avoiding dental visits.
"Some patients may feel that if they aren't in pain, then there's no need for a checkup. That is not correct," said Dr. Andrew J. Kwasny, president-elect of PDA. "Patients need to come in for checkups to catch and prevent problems, which otherwise could quickly advance into painful tooth disease and costly treatments."
For example, a patient with a minor toothache may decide to treat it with numbing gel rather than visit a dentist. That toothache could be the symptom of tooth decay, and the longer it remains untreated, the more likely it will later require a root canal and crown.
The tough economic times could also be causing an increase in another dental problem called bruxism, more commonly known as teeth grinding. Frequently linked to stress, which increases during bad economic times, bruxism often remains unnoticed by most patients until their dentist brings it to their attention. Left untreated, a bruxing patient will rapidly wear down his or her tooth enamel, then the layer underneath, ultimately causing teeth breakage. Caught early by a dentist, however, bruxism is easily treatable.
"Avoiding the dentist is not a good way to save a few bucks," said Dr. David A. Tecosky, a member of PDA's Council on Communications and Public Relations. "Checkups aren't just about preventing cavities, dentists also check for more serious conditions like cancer and jaw diseases. Lack of treatment can also lead to health problems beyond oral health, or exacerbate existing ones like diabetes and heart disease. Poor oral health care can compromise one's ability to eat, to smile, or even to get a job."
Dentists advise patients to come in for a checkup every six months. In between visits, their most important general recommendations are that patients:
-- Floss at least once a day.
-- Brush teeth twice daily for at least two minutes each time.
-- Remember to brush all tooth surfaces, as well as the tongue.
PDA also urges patients concerned about the cost of a checkup to contact their dental practice, as many offices are willing to work out a payment plan. Pennsylvanians may also check out PDA's website, which features a directory of free and low-cost dental clinics around the state.
