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.

Metal Allergies & Temporomandibular Disorders

  • Dec 7, 2013

Two articles in the British Journal of Oral and Maxillofacial Surgery report: 1) a high number of metal allergies in Temporomandibular Disorders (TMD) patients needing total replacement of their TM joints and 2) one year follow-up data comparing patients with metal allergies treated with all titanium total joint replacements (considered non-allergenic) with non-allergic patients treated with standard cobalt-chromium replacements joints.

Allergies

Two investigators from Nottingham University Hospitals, A. J. Sidebottom and K. Misty, used patch tests to detect metal allergies in all patients needing a total joint replacement between March 2004 and August 2012. Of these 101 patients, a startling 39 percent tested positive for allergy to one or more metals and were given all titanium prostheses. The investigators report that as of six months follow-up, no patient showed signs of an allergic rejection.

Titanium vs. Cobalt-chromium

Dr. Sidebottom and two other colleagues, S. Sah and O.T Hussain, studied all patients who had joint replacements with one-year follow-up in the period from March 2003 and February 2011. Of these 55 patients, 40 had the standard cobalt-chromium prosthesis, while 15 had all-titanium. The most common disease in both groups was osteoarthritis. Judged on the basis of pain relief, improved mouth opening, and diet scores, both groups of patients benefited with no significant differences between groups. No patient developed a hypersensitivity reaction, and no all-titanium prosthesis failed (at least as of one-year follow-up).
