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.

Dental Occlusion & Body Posture - A Review of Existing Studies

  • Dec 25, 2013

Dental occlusion, body posture and temporomandibular disorders: where we are now and where we are heading for
Manfredini D, Castroflorio T, Perinetti G, Guarda-Nardini L. Oral Rehabilitation, 2012.

The relationship between abnormaldental occlusion, body posture and development of Temporomandibular Disorders (TMD) has been a controversial subject for many years. Based on such concepts, many patients have been subjected to extensive and expensive treatments purported to correct existing occlusal and postural abnormalities. In this article, the authors review the existing literature on this subject, as well as the validity of the various devices and clinical methods that have been used to measure this relationship.

These include surface electromyography (an electrical recording of muscle activity that aids in the diagnosis of neuromuscular disease), kinesiology (the study of the anatomy, physiology, and mechanics of body movement) and postural platforms (devices that measures changes in body position), that have been used to measure this relationship.

Their results show that the literature does not support the idea that occlusal alterations are associated with either the development of temporomandibular joint problems or masticatory muscle disorders, nor is there any relationship to variations in head and body posture. Thus, they conclude that a mechanical approach to treating TMD by means of irreversible methods such as occlusal adjustments, full mouth dental reconstructions or orthodontics is not justified from a scientific viewpoint.

This summary was written by our clinical advisor, Dr. Daniel Laskin. Dr. Laskin is The TMJ Association's Clinical Consultant, and Professor and Chairman Emeritus at the Virginia Commonwealth University, Department of Oral and Maxillofacial Surgery in Richmond, VA.
