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.

The Throb that is Not a Heartthrob

  • Dec 19, 2013

Because pain is a subjective experience, patients are often asked to describe their pain in words. The result is a rich set of adjectives like sharp, dull, burning, and throbbing. In particular, a throbbing quality often describes pain that is severe and disabling. It was commonly thought such patients were sensing the actual pulsing of blood through their arteries. Apparently not, say researchers at the University of Florida in Gainesville.

Andrew H. Ahn in the Department of Neurology in the medical school and colleagues began by noting that throbbing pain has been associated with a wide range of painful conditions, including nerve injury, leading them to suspect that the throbbing reflected something going on in the nervous system. Then they had occasion to study a woman with a history of throbbing pain from daily migraine headaches. She was successfully treated so her headaches resolved but she continued to experience chronic throbbing sensations in her head (without pain). She volunteered for an electroencephalogram (EEG) study, which would record brain wave activity while she simultaneously used a digital recorder to tap out the throbbing rhythm she felt. The results showed that her throbbing beats had no relation to her heart rate, but were in perfect synchrony with alpha wave activity in her brain. Alpha waves represent a large- scale synchronous activity of brain nerve cells, which are thought to be the basis for communication across distant but functionally related brain regions.
