New Report on Temporomandibular Disorders: Priorities for Research and Care

Over a year and half ago, the National Academy of Medicine (NAM) began the most comprehensive study ever undertaken on Temporomandibular Disorders (TMD). The study assessed the current state of TMD research, education and training, the safety and efficacy of clinical treatments, and associated burden and costs.

Statement by NIDCR Acting Director on the National Academies of Sciences, Engineering, and Medicine Report on Temporomandibular Joint Disorders

I am pleased to announce the release of the National Academies of Sciences, Engineering, and Medicine (NASEM) report, Temporomandibular Disorders: Priorities for Research and Care. As underscored by the comprehensive report, temporomandibular joint disorders (TMJDs) are a diverse and still poorly understood set of complex, painful conditions affecting the jaw muscles and tissues, temporomandibular joints, and associated nerves. Clearly, there is much more to be understood, and these conditions continue to confound medical and dental health care providers and researchers.

Have you seen the film Dark Waters?

The Film. Dark Waters is about attorney Robert Billott's real-life 20 year legal battle against DuPont chemical for releasing toxic waste - perfluorooctanoic acid, or PFOA - into Parkersburg, West Virginia's water supply, with devastating health effects on the townspeople and livestock. PFOA, also known as C8, is a man-made chemical. It is used in the process of making Teflon and similar chemicals known as fluorotelomers.

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.

Botulinum Toxin Treatment of Myofascial Pain: A Critical Review of the Literature

  • Dec 25, 2013

In this review, the author used PubMed to search the literature for studies involvling the use of botulinum toxin for treating myofascial (muscle) pain. Included in the review were open-label studies, single-blinded and double-blinded studies, randomized and controlled, or not.
Based on his findings, the author concluded that there is insufficient evidence at the current time to guide clinical practice. Because he included such diverse types of studies, many of which were not blinded or controlled, it should be expected that the review would not provide a definitive answer.
However, even if it had shown a positive result, there are other reasons to question the use of botulinum toxin for this purpose. First, it does not address the cause of the problem but rather attempts to treat the symptoms. Second, it provides only temporary relief in most instances and, therefore, needs to be repeated. Finally, its use is not without possible complications, including disfiguring muscle atrophy when repeated multiple times.

Our thanks to Dr. Daniel Laskin for providing us with the summary of this study by R. Gerwin, which was published in Current Pain and Headache Reports, 7/18/12. Dr. Daniel Laskin is the TMJA's Clinical Consultant and Professor and Chairman Emeritus at the Virginia Commonwealth University, Department of Oral and Maxillofacial Surgery in Richmond, VA.
