Metal Implants and Dental Amalgam: The FDA Announces Public Meeting and Paper

The U.S. Food and Drug Administration (FDA) announced a paper on metal-containing implants and a panel meeting as part of ongoing efforts to evaluate materials in medical devices to address potential safety questions.

Drug Induced Bruxism

The authors of this article state that orofacial movement disorders (bruxism) are treated typically by dental professionals and not by those specialists (neurologists) researching and treating the other movement disorders (Parkinson's disease, Huntington's disease, tremors, etc.). Again, this is more evidence of the complexity of TMD and the need for multidisciplinary research and treatment in TMD.

Cervical Muscle Tenderness in Temporomandibular Disorders and Its Associations with Diagnosis, Disease-Related Outcomes, and Comorbid Pain Conditions

To analyze cervical tenderness scores (CTS) in patients with various temporomandibular disorders (TMD) and in controls and to examine associations of CTS with demographic and clinical parameters.

You, Your Esophagus and TMD

The esophagus is a roughly ten-inch hollow tube that descends from your throat through the diaphragm into the stomach. Normally, it is a one-way street transporting food you swallow to the stomach for digestion. But in GERD— Gastroesophageal Reflux Disease— the flow can reverse so that stomach contents (including gastric acids) are regurgitated upwards to cause a burning sensation (heartburn), nausea, pain and other distressing symptoms.

It's Time to Be Part of the Solution

The National Academy of Medicine (NAM) Study on Temporomandibular Disorders (TMD) is well underway. We strongly encourage everyone affected by TMD to write to the NAM committee letting them know what it is like to live with TMD and your experiences with getting care.

TMJA's Sixth Scientific Meeting: A Paradigm Shift

  • Dec 19, 2013

The TMJA held its 6th international scientific conference June 5-7, 2011, at the Federation of Societies for Experimental Biology Conference Center in Bethesda, MD. 

The topic: Comorbid Chronic Pain Conditions—Mechanism, Diagnosis and Treatments—followed up on the Association’s scientific meeting of 2008, which initially explored the topic of comorbidities (conditions that occur together more often than chance can explain). In the interim, there has been further evidence that TMD patients often experience other chronic pain conditions, including endometriosis, fibromyalgia, chronic fatigue syndrome, migraine and chronic headaches, irritable bowel syndrome, chronic pelvic pain, vulvodynia, and interstitial cystitis.

The meeting was a resounding confirmation that there must be some underlying mechanism that links the conditions in question, and that the answer may lie in the nervous system.

Instead of looking for clues in the end organ—the jaw, the intestine, the reproductive tissues—the focus should be on how the nervous system has changed because of chronic pain, becoming hypersensitive and dysfunctional. This is a paradigm shift and attendees agreed it should inform how future research should be conducted.

The meeting was attended by scientists with unusually diverse research expertise in chronic pain disorders and other research areas. The significance of the meeting was underscored by the participation of seven National Institutes of Health Institutes, Office, and Center Directors; the leaders of four patient advocacy organizations comprising the Chronic Pain Research Alliance; and numerous NIH Program Staff. Following the formal presentations, attendees developed recommendations that are being disseminated to the research community.

Now that the pain issue has been brought to the forefront, the TMJA will encourage research to explore the interactions between the TM joint and the nervous system that give rise to chronic pain.
