The American Association for Dental Research has revised it’s 1996 policy statement on Temperomandibular disorders (TMD). The AADR recognizes TMD as a group of musculoskeletal and nueromuscular conditions that involve the temeromandibular joint (TMJ), muscles of mastication (chewing), and all associated tissues. The two recommendations support the information in my previous Blogs. First, the diagnosis should be based on information from talking to the patient and a clinical examination. Imaging should be chosen on a case by case basis. Adjunctive diagnostic procedures need to be based on peer reviewed data showing effectiveness and safety. Second, treatment of TMD patients should be based on conservative and reversible modalities.
