Evolve® Dental Technologies, Inc. Introduces theKöR Whitening Deep Bleaching™ System





I am at the Chicago Midwinter Meeting learning about The KoR Deep Bleaching System and Dr. Kurthy is presenting impressive results.

Evolve® Dental Technologies, Inc. Introduces the
KöR Whitening Deep Bleaching™ System by Dr. Rod Kurthy

Whitening System Yields Reliable, Consistent Results on
Even the Most Resistant Cases without Pain or Sensitivity

Rancho Santa Margarita, CA (February 28, 2009) - Evolve® Dental Technologies, Inc., an innovative research, development, and dental product sales company, is introducing the latest and most effective technique developed for whitening teeth, the KöR Whitening Deep Bleaching™ System. Developed by Dr. Rod Kurthy, the KöR Whitening Deep Bleaching System is regarded by current users as the most effective whitening method available.
The KöR Whitening Deep Bleaching System provides predictable and intense whitening results, even on tetracycline-stained cases, and has solved the bleaching sensitivity issue by developing a system that protects the tooth’s pulp from the bleaching product. Furthermore, Evolve is the first bleaching product company to refrigerate their entire line of bleaching gels from the instant of manufacture until received by the dental practice. This ensures superior and consistent efficacy.
With the introduction of the KöR Whitening Deep Bleaching System, dental professionals and patients now have access to low-sensitivity bleaching and the physical properties necessary to achieve ideal results. Patients who previously were unable to bleach as white as they would have liked because of bleaching-resistant teeth or acute sensitivity can now achieve significantly whiter teeth.
Currently, there is no one-visit, fast bleaching technique on the market that provides optimal whitening of the teeth. However, from start to finish, Dr. Kurthy has developed a system that rejuvenates the tooth’s ability to whiten predictably and fully, every time, beginning with the bleaching tray impression technique.
Dr. Kurthy’s impression technique is designed to make custom bleaching trays, fabricated with a unique design and impeccable fit that effectively seals the bleaching gel in the trays, extending the effectiveness of bleaching from only approximately 25-35 minutes to six or more continuous hours. When using conventional bleaching trays, not only do teeth not get as white as desired, but many times the portion of the teeth closest to the gum line remains quite dark. This occurs for two reasons: Most bleaching trays do not create a true seal at the edge, and saliva and gingival sulcular fluid seep under the trays, inactivating the bleach, most quickly near the gum line. Since enamel is thinner near the gum line, the darker dentin inevitably shows through.

The extremely precise KöR Whitening Deep Bleaching™ Tray Impression Technique perfectly captures the gingival margin and the sulcus in the impression. In fact, the detail captured and the dimensional stability of the impressions is so impeccable, many dental professionals are currently using this technique for crown and bridge impressions.
Many problems associated with bleaching are actually not rooted in the bleaching tray, but the impression itself. Dr. Kurthy’s specially formulated impression material and technique ensures that no saliva seeps under the bleaching tray, so there is no risk of bleaching gel inactivation. The hydrophilic polyvinyl siloxane impression blend can be used for both KöR Whitening and crown and bridge impressions. The material ensures a crisp, detailed, and sharp gingival margin, without bubbles.
The KöR Whitening Deep Bleaching System was designed by Dr. Kurthy to achieve superior Deep Bleaching results, but with much less of the common sensitivity and pain associated with other bleaching gels. KöR Whitening Deep Bleaching is the first system to provide a desensitizer that also provides whitening enhancement to speed the bleaching process. First applied in the dental office, desensitizer is then provided to the patient, allowing them to liberally apply it to both arches at home during the bleaching process.
“How permeable your tooth structure is to oxygen is one of the main determinants of how white and how quickly your teeth will respond to a whitening procedure,” remarked Dr. Kurthy. “I have developed a system to actually condition the teeth to absorb oxygen no matter how old or stained. If the tooth structure does not readily absorb oxygen, it does not matter how strong a bleaching gel is.”
The KöR Whitening process starts with the sophisticated, super-accurate impression of the teeth and gum line using Dr. Kurthy’s impression system. The patient then returns for a very simple in-office bleaching using a highly specific hydrogen peroxide in order to start conditioning the teeth. The bleach is simply applied in the KöR Whitening Deep Bleaching Trays – no retractors or paint-on dam are necessary. During this time, two separate desensitizers are applied by the dental staff. One desensitizer also acts as a whitening conditioner that is clinically proven to speed up the whitening process.
Next, the patient will typically wear KöR Whitening Deep Bleaching Trays at home during sleep for two weeks. The patient is provided a desensitizer, as well as carbamide peroxide bleaching gel with the specific physical properties to maximize full release of oxygen over several hours in KöR Whitening Deep Bleaching Trays each night. During this time, the patient will notice a remarkable whitening result. In addition to becoming whiter, the teeth are also now more conditioned (more permeable to oxygen) deeply into the tooth, resulting in greater whiteness and longer-lasting results.
Some patients object to nighttime wear of conventional bleaching trays because rapid gel leakage into the mouth and uncomfortable fit may prevent sleep. KöR Whitening Deep Bleaching Trays prevent rapid leakage of bleaching gel, and fit so well that patients often forget the trays are in their mouths. Objections by patients disappear after seeing the photos of KöR Whitening Deep Bleaching Trays in the mouth (photos are included with the KöR Whitening Deep Bleaching Training Manual). Patients find that nighttime wear is easy and comfortable, preventing the need to find time to wear bleaching trays during their busy days.
Lastly, the process is complete with one final visit to the dental professional. At the final in-office visit, the teeth have already been fully conditioned to easily absorb oxygen from the bleaching gel. A high-concentration hydrogen peroxide gel is then placed on the teeth for approximately one hour. Because of the whiteness already achieved, plus the “conditioned” ability for oxygen from the high-concentration hydrogen peroxide to fully enter the crystalline structure of the tooth, the final results are truly remarkable. An additional detonation of whiteness will occur during this visit, resulting in a beautiful white smile.
Two levels of strength for the in-office bleaching gels are available: KöR Whitening Standard Deep Bleaching™ and KöR Whitening Deep Bleaching™ MAX. The Standard Deep Bleaching gel utilizes a highly accelerated 9% hydrogen peroxide for the first and second in-office sessions.
The KöR Whitening Deep Bleaching MAX gel is intended for use on particularly bleaching-resistant cases such as tetracycline staining, and for routine use by those dentists who always want the whitest possible result. It utilizes the same 9% hydrogen peroxide for the first in-office session. However, a very accelerated and potent 27% hydrogen peroxide is used for the second in-office session and requires a paint-on dam and retractors.
Storage in hot warehouses and shipping in hot trucks quickly damages bleaching gels. Evolve is the first company to continuously refrigerate a full line of bleaching gels from the moment of manufacture until received by the dental office. This is the first time ever that dentists can routinely receive a full line of bleaching gels that are at virtually 100% of their original effectiveness.

Durability Of Dental Fillings Improves If The Enzyme Activity Of Teeth Is Inhibited

A dental filling is more durable if the enzyme activity of the tooth can be inhibited. Professor Leo Tjaderhane of the Department of Pedodontics, Cariology and Endodontology at the University of Oulu, together with wide international collaborative team, has been developing this method with funding from the Academy of Finland.

Composite dental fillings have one problematic feature, in that the bond between the filling and the dental tissue deteriorates over time – in fact, sometimes by as much as 50 per cent in one year. As the bond deteriorates, it may allow bacteria to enter and this brings a high risk of further tooth decay.

Professor Tjäderhane has researched the occurrence of certain enzymes, matrix metalloproteinases (MMPs), in the dental tissue and their role in dental conditions. The MMPs break down the extracellular matrix, including collagen, which is a major component of dentin. As a result of international research collaboration, Tjäderhane's research team has shown that human dentin contains the key MMP for breaking down collagen. The bonding of composite resins with dental tissue is based on the use of collagen bonds, and the tooth's own MMPs are responsible in part for the deterioration of the bond over time. By inhibiting the activity of these enzymes, the research team has succeeded in significantly slowing down the deterioration of the bond between dental tissue and a composite filling, and in some cases to prevent deterioration completely.

The best results have been obtained in clinical trials, where deterioration of the bond has been more or less completely prevented. MMP enzyme activity in the tooth can be rapidly and easily inhibited when a filling is put in place by using chlorhexidine, a substance which is already on hand at all dental practices. This means that the research results are immediately applicable in dental care for the best benefit of the patients. The research in question also strongly indicates that MMP inhibitors might help slow down tooth decay. These observations are based only on animal testing so far, so further research on the subject will be needed before pratical applications can be made available.

Abfraction: separating fact from fiction

Michael JA, Townsend GC, Greenwood LF, Kaidonis JA.
Aust Dent J. 2009 Mar;54(1):2-8.

School of Dentistry, The University of Adelaide, South Australia.

Abstract Non-carious cervical lesions involve loss of hard tissue and, in some instances, restorative material at the cervical third of the crown and subjacent root surface, through processes unrelated to caries. These non-carious processes may include abrasion, corrosion and possibly abfraction, acting alone or in combination. Abfraction is thought to take place when excessive cyclic, non-axial tooth loading leads to cusp flexure and stress concentration in the vulnerable cervical region of teeth. Such stress is then believed to directly or indirectly contribute to the loss of cervical tooth substance. This article critically reviews the literature for and against the concept of abfraction. Although there is theoretical evidence in support of abfraction, predominantly from finite element analysis studies, caution is advised when interpreting results of these studies because of their limitations. In fact, there is only a small amount of experimental evidence for abfraction. Clinical studies have shown associations between abfraction lesions, bruxism and occlusal factors, such as premature contacts and wear facets, but these investigations do not confirm causal relationships. Importantly, abfraction lesions have not been reported in pre-contemporary populations. It is important that oral health professionals understand that abfraction is still a theoretical concept, as it is not backed up by appropriate clinical evidence. It is recommended that destructive, irreversible treatments aimed at treating so-called abfraction lesions, such as occlusal adjustment, be avoided.

Sweden Bans Mercury- amalgam included

Last month, the government of Sweden issued a blanket ban on the use of mercury. The ban, which will go into effect on June 1, covers all uses of mercury, including in dental amalgam. The action by the Swedish government was taken for environmental reasons and does not address any safety concerns over dental amalgam. As a practical matter, the impact on dental care in Sweden will likely be minimal because amalgam is seldom used there. The new rules in Sweden do leave open possible exceptions to the ban being granted in individual circumstances. The announcement from the Swedish government may be found here: http://www.sweden.gov.se/.

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."

ClearCorrect, Inc. Files Declaratory Judgment Against Align Technology, Inc. the Maker of Invisalign®


Houston, TX – February 17, 2009 – ClearCorrect, Inc., a manufacturer of FDA-cleared transparent orthodontic aligners, commonly known as clear braces or invisible braces, today filed a declaratory judgment against Align Technology, Inc., the manufacturer of Invisalign®. The suit was filed in the United States District Court for the Southern District of Texas, Houston Division.

By definition, a declaratory judgment is a court decision in a civil case that tells the parties what their rights and responsibilities are, without awarding damages or ordering them to do anything. Unlike most court cases, where the plaintiff asks for damages or other court orders, the plaintiff in a declaratory judgment case simply wants the court to resolve an uncertainty so that it can avoid future litigation and associated costs.

Specifically, ClearCorrect has filed a complaint that alleges that certain patents owned by Align Technology (Invisalign) are invalid and that ClearCorrect’s clear braces products and processes do not infringe upon those patents.

According to ClearCorrect’s attorney, Randy J. McClanahan of Houston-based law firm McClanahan, Myers and Espey, LLP, “This suit was filed against Align Technology not to prevent Align from conducting business, but to ensure that ClearCorrect could compete openly and fairly in the market for clear orthodontic aligners without threat of litigation by Align.”

“Fortunately for us, the Constitution provides protection in these ‘David vs. Goliath’ situations,” explained ClearCorrect CEO and practicing Houston dentist, Dr. Willis Pumphrey. “We are merely trying to avoid protracted litigation such as Align’s suit against Ormco Corporation, which took six years and untold legal costs to eventually prove the invalidity of several of Align’s patent claims. We are willing to voluntarily dismiss our suit if Align provides assurance that it will not initiate similar litigation in the future.”

About ClearCorrect, Inc.

Headquartered in Houston, Texas, ClearCorrect was founded by dentists to serve the dental and orthodontic industry by providing a superior and more affordable clear aligner system. The highly-sophisticated ClearCorrect treatment delivery system and corresponding aligner products are based on years of research and clinical experience.

The way it's supposed to be!

Today I had a new patient who had a recent panorex and bitewing radiographs in another office. A quick call over and within minutes the radiographs where in my office email inbox. That is the way things should be. I get the best diagnostic quality and no waiting around. Sure beats the lousy copies of digital radiographs that circulate around on regular copy paper. Now if we only had true DICOM software installed (without additional cost) with every dental radiography package, things would be even better.

My New Netbook- Dell Mini 9


I bought my daughter a NetBook computer as a second computer for college. A Netbook is just a small computer. I bought her an EEE PC. I thought I could use one too as I travel a lot and I felt the Macbook is just too large at times.

So I bought a Dell Mini 9. from the Dell Outlet store. It has an 8.9 inch screen and a 8GB SSD along with 1GB of RAM. The choice was Ubuntu Linux or Windows XP. I wanted the least expensive model with all the bells and whistles in it. So it cost $240 with the 1.3 MP web cam and Bluetooth. I got the Ubuntu version. I got the Mini 9 and it rocked. Very fast ( as fast as a 1.6GHz processor can be) and was a lot of fun. No fans, no noise just a great little computer.

Well of course that would not be good enough. While I was waiting for delivery of the Mini 9 I ordered a 2GB RAM stick and a 32 GB SSD. I needed more memory so I could do presentations from the Mini 9. So I upgraded the hardware and installed Mac OS X on it (No you cannot easily do this but it can be done). So now I have a small MacBook Nano as I call it. I set it up to connect to the Internet through my Palm Centro. So anyplace I go this little 2 pound computer can come and get online.

Abstract
Purpose Since both obstructive sleep apnoea (OSA) and periodontitis are associated with systemic inflammation and cardiovascular morbidity, we questioned whether there may be an association between these two disorders.
Materials and methods A standard periodontal examination was undertaken in a group of 66 (54 men and 12 women) treatment-naïve patients diagnosed with OSA [apnoea–hypopnoea index (AHI) >5/h] to derive a number of quantitative variables which could then be used to determine the prevalence of periodontitis in a group of patients.
Results The prevalence of periodontitis in our study group was 77–79%, depending on the definition used. This was almost four times that of historical controls derived from a recent national survey. When sleep-related variables were compared against periodontal variables, significant correlations were found between periodontal clinical attachment level and total sleep time.
Conclusion Our pilot study suggests that OSA is associated with periodontitis. Further research is needed to elucidate the nature of this association.

Safety guide launched for new 3-D dental scans

Important new guidelines for dentists using the latest three-dimensional imaging system in their surgeries have been established for UK and European practitioners.

Cone Beam Computed Tomography (CBCT), which gives a similar kind of image as a medical CT scan, is now available in high-street dental practices to give high-definition, three-dimensional scans of patients’ jaws and teeth.

However, CBCT carries an increased risk associated with greater radiation dose than traditional dental X-rays, so the European Academy of Dental and Maxillofacial Radiology (EADMFR) has developed 20 ‘Basic Principles’ for use of CBCT in dentistry.

The guidelines, which establish the safe and ethical use of CBCT, have been drawn up by the EADMFR in collaboration with the EU-funded SEDENTEXCT project, which was set up to conduct research into the use of CBCT in dentistry.

“In many European countries, dentists can purchase and use CBCT without any additional training and so there was a pressing need to establish some guidelines,” explained SEDENTEXCT coordinator Professor Keith Horner, who is based at The University of Manchester.

“The 20 Basic Principles are aimed at protecting the patient and guiding the dentist towards good practice covering important areas such as justification and optimisation of CBCT examinations and training of users.”

Among the Basic Principles are guidelines about when CBCT examinations may be justified, as well information about training, equipment and safety measures.

Dr Lennart Flygare, EADMFR President, said: “We hope that this document will be a core standard within Europe for dentists, dental specialists and equipment manufacturers.”

ABSTRACT

Objectives: To compare salivary pH changes and stimulation efficacy of two different gustatory stimulants of salivary secretion (GSSS).

Setting: Portuguese Dental Faculty Clinic.

Design: Double blind randomized controlled trial.

Subjects: One hundred and twenty volunteers were randomized to two intervention groups. Sample sized was calculated using an alpha error of 0.05 and a beta of 0.20.

Materials and methods: Participants were randomly assigned to receive a new gustatory stimulant of secretory secretion containing a weaker malic acid, fluoride and xylitol or a traditionally citric acid-based one. Saliva collection was obtained by established methods at different times. The salivary pH of the samples was determined with a pH meter and a microelectrode.

Main outcome measures: Salivary pH variations and counts of subjects with pH below 5.5 for over 1 min and stimulated salivary flow were the main outcome measures.

Results: Both GSSS significantly stimulated salivary output without significant differences between the two groups. The new gustatory stimulant of salivary secretion presented a risk reduction of 80 ± 10.6% (95% CI) when compared with the traditional one.

Conclusions: Gustatory stimulants of salivary secretion with fluoride, xylitol and lower acid content maintain similar salivary stimulation capacity while reducing significantly the dental erosion predictive potential.

The AAP Issues Statement on Periodontal Treatment During Pregnancy

CHICAGO–January 30, 2009–Research recently presented at the annual meeting of the Society for Maternal-Fetal Medicine found that routine periodontal treatment in pregnant women did not reduce the risk of preterm deliveries. Some previous studies in this area have suggested that periodontal therapy during pregnancy can lessen the chance of adverse pregnancy outcomes.

While the American Academy of Periodontology (AAP) has not yet received the opportunity to review the complete study findings, it continues to urge women to care for their periodontal health while pregnant, through regular tooth brushing and flossing, and routine visits to a periodontist to screen for periodontal disease.

These study results demonstrate the need for additional research to clarify the potential impact that periodontal disease has on the risk of preterm births; and if needed, what periodontal treatment modalities are most effective in helping to prevent premature deliveries.

Improving the oral health of older people in long-term residential care: a review of the literature

International Journal of Older People Nursing
Published Online: 5 Feb 2009

Karen Miegel RN and Tracey Wachtel RN, MN, MRCNA Grad Cert HD Nursing
Graduate Registered Nurse, Riverland Regional Health Services, Berri, SA, AustraliaLecturer in Nursing, School of Nursing and Midwifery, Flinders University Renmark Campus, Renmark, SA, Australia

ABSTRACT

Background. Unrefutable evidence now links poor oral health with the development of preventable systemic illnesses and debilitating conditions that threaten quality of life and life itself. This is especially significant for an increasing older population who are dependent on others for care.

Aims and objectives. The majority of studies analysing the oral health of older dependent people in long-term residential care have been undertaken by dental professionals. This critical literature review examines the issue from a nursing perspective because nursing care providers have a fundamental role in daily oral health provision for dependent residents.

Conclusions. Multiple barriers were found to negatively impact on daily oral healthcare provision, including lack of care provider education, oral health values, availability of resources, implementation of supportive policies, documentation and oral health assessment tools.

Relevance to clinical practice. The nursing profession, at all levels, must become pro-active in removing financial, political and workforce barriers that impact negatively on oral health outcomes. A multi-faceted approach is required to address these barriers, including development and implementation of oral health education programmes, assessment screening tools, care plans, documentation, supply of oral hygiene aids and the appointment of oral care 'champions'.

NEXT-GENERATION CANCER SCREENING DEVICE INTRODUCED


HOUSTON, TX: February 4, 2009 — Houston-based Trimira™ LLC has introduced Identafi™ 3000, a small, cordless, handheld device that can detect oral cancer. The device uses a three-wavelength optical illumination and visualization system to allow dental professionals to catch early cancers not visible to the naked eye. This effective and affordable device will aid in early detection of oral cancer, which has reached epidemic levels, due in part to the lack of effective, broad-based early detection programs.

Identafi 3000 uses white, violet, and amber wavelengths of light to excite oral tissue in distinct and unique ways. Biochemical changes can be monitored with fluorescence, while morphological changes can be monitored with reflectance. This multiple wavelength technology identifies abnormal tissue with more accuracy than the single color approaches currently on the market. The ability to read metabolic and physiologic differences makes it easier to distinguish between normal and abnormal tissue. The combined system of fluorescence and reflectance uses the body's natural tissue properties as an adjunctive tool for oral mucosal examination.

Identafi 3000 is supported by a national team of trained sales representatives and is available through most major U.S. dental dealers. It can be seen at the Chicago Midwinter Meeting, in the Trimira booth, #865.

TRIMIRA™ LLC is a subsidiary of Remicalm LLC, a privately held medical diagnostic and imaging device company. Other subsidiaries are working on screening and diagnostic devices for skin, cervical, gastrointestinal, and bladder cancers. Remicalm's core technologies are based on high-speed, high-resolution capabilities from its patented optical processing technology platforms and include the ability to read metabolic and physiologic differences in diseased and healthy tissue in the human body.

Dentists Facing Depression And Suicide

An article published in the Journal of the Canadian Dental Association claims that many dentists are at risk of suffering from a chronic mood disorder known as dysthymia. It's a condition the Université de Montréal Department of Dentistry is fighting - preventively.

Dysthymia is characterized by loss of appetite, low levels of energy, desperation, excessive anger, social withdrawal and working long hours to compensate for declining performance, troubles in concentration, guilt and suicidal thoughts.

A 2005 study published in the Journal of the American Dental Association claims that 10 percent of the 560 dentists surveyed suffer from this condition. However, only 15 percent of them are followed by a doctor and receive treatment.

Wwhat about dentists in Canada and Quebec? The Ordre des dentistes du Québec doesn't have data on the depression and suicide rates of its 4,360 practitioners. That doesn't make the issue any less real according to Gilles Lavigne, dean of the Université de Montréal Faculty of Dentistry.

"When I was a student, we were already sensitized to this particularity of the profession," says Dr. Lavigne. "But it is a problem that affects all health professionals, not just dentists."

In 1998, the Université de Montréal established a prevention program to help future dentists cope with stress before irritability and exhaustion lead to depression. The program includes information and training on the issue. In addition, the curriculum now includes two psychology classes that focus on the theory and practice of the stress a dentist will face.

Dr. Lavigne has known depressive individuals who have committed suicide, and he feels reassured by the prevention program now in place. "To my knowledge, there hasn't been a fatal act at the Faculty of Dentistry in the past 10 years," he says. "The program seems to have had the intended preventive effect. And depression is less stigmatized today, contrarily to my generation, youngsters today speak about it more openly. This helps us provide them with better support."

Maryland Dental School To Help Solve Mystery Of TMJ Jaw Pain

For millions of people with mysterious pain of the jaw region, there may be help on the way.

Researchers at the University of Maryland Dental School hope their new seven-year, $17 million study of 3,400 study subjects will finally identify the cause and effect, and point to possible cures for temporomandibular joint and muscle disorders (TMJD).

For most people, the discomfort from the commonly called "TMJ" group of disorders will eventually go away with little or no treatment says the National Institute of Dental and Craniofacial Research (NIDCR) in Bethesda. However, many TMJD patients develop significant, long-term problems that cause chronic pain and dysfunction in the jaw joint and muscles that control jaw movement.

As much as 2 percent of the U.S. population suffers from TMJD, with more women than men appearing to have the condition, but doctors and scientists know little about the causes, and so there are few effective treatments.

Joel Greenspan, PhD, a professor and chair of the Department of Neural and Pain Sciences at the Dental School, says that most people know someone with the disorder or have heard their doctor suggest that a pain may be TMJD. "But, there is often little or nothing physically wrong that can be identified. And, frequently the pain is not specifically focused or limited to the jaw," he says.

Common characteristics of TMJD include pain, limitations in mobility and function, and jaw joint noises�"�clicks, pops, catches, or locks when the mouth is opened. TMJD is the second leading cause of pain for people who report facial or head pain.

Greenspan is one of the principle investigators in the $17 million "Orofacial Pain: Prospective Evaluation and Risk Assessment" (OPPERA) study, funded by the, NIDCR, which is part of the National Institutes of Health. OPPERA is being conducted at four sites, the University of Maryland Dental School, and the universities of Buffalo, North Carolina, and Florida dental schools. It is headed by William Maixner, DDS, PhD, Center for Neurosensory Disorders, School of Dentistry, University of North Carolina.

In some cases, the disorder can be brought on by trauma. Greenspan said some dental procedures can bring it on, but that is uncommon. It can also be brought on by misalignment of teeth, which is most often hereditary. Overuse of the jaw is another possible cause. Excessive gum chewing, nail biting, and gnawing on items like plastic straws can overtax the muscles of this joint.

"The main purpose of our OPPERA study is to identify the precursors in a prospective way, thus allowing us to more formally determine cause and effect, rather than just associations", said Greenspan. He said there have been very few studies that address the cause of the disorder in a prospective manner, and none of the size and comprehension of OPPERA. Almost all of the clinical literature studies on TMJD are either observations on TMJD patients, or case-control studies.

Historically, doctors routinely recommended surgery to try to correct TMJD, but surgery is no longer a leading recommendation. Dental treatments include filing teeth down to make them fit better in the bite, or using dental appliances to even out the bite, like a match box under a table leg. "But, sometimes grinding makes things worse and may not be the answer. Noninvasive techniques are better recommended, such as appliances or reduced stress through exercise," said Greenspan.

TMJD occurs at least two times more frequently in women than in men, and often with more severe symptoms in women, perhaps because women are more pain sensitive, he said. "Several studies conducted here and elsewhere have shown that under controlled test conditions, women report standard test stimuli as more painful than men. Recent testing we have completed indicates that the brain's processing of pain is amplified more in women than men, and even more so in women suffering with TMJD."

In an NIDCR survey of 42,370 adults, (ages 18 to 75 and older) over a six-month period prior to Dec. 20, 2008, 3.5 percent of males and 6.9 percent of females reported pain in the jaw joint or in front of the ear more than once. The average for participants ages 75 and older of both sexes combined was 3.9 percent, but the average for those in the 18 to 34 year old group was 6.5 percent.

One mystery of the disorder is that the pain is not necessarily directly focused on the jaw, while another is that the pain is not related to the extent of tissue injury. This doesn't surprise Greenspan because, he says, pain is the result of multiple system changes. "This is a complex area," he says, involving the three factors underlying pain: genetics, psychology, and physiology.

Dental Treatments Don’t Stop Preterm Births

Treating Periodontal Disease During Pregnancy Did Not Reduce Preterm Birth Rates, Study Shows

The study, which included 1,800 pregnant women with periodontal disease, was presented today in San Diego at the 29th annual meeting of the Society for Maternal-Fetal Medicine.

Similar findings were reported in a separate trial involving 823 women; those findings were published in the New England Journal of Medicine in late 2006.

Both studies compared outcomes among women with periodontal disease who did and did not receive routine tooth and gum treatment during pregnancy.

"I think it is pretty clear that the type of treatment used in these studies does not reduce the risk of premature delivery," ob-gyn professor Robert L. Goldenberg, MD, of Philadelphia's Drexel University, tells WebMD.
