Report on acceptance of TMD devices

Article Abstract:

The American Dental Association (ADA) recently approved two electronic instruments that measure muscle activity that may enable dentists to better diagnose and treat temporomandibular disorders (TMD). TMD involves pain and dysfunction of the jaw joint and muscles. The BioEMG and the K6 I/EMG Electromyograph were approved by the ADA's Council on Scientific Affairs. Surface electromyography (EMG) measures the activity of the chewing muscles to diagnose the type of TMD. The ADA stresses that correct diagnoses must include the patient's main complaint, medical and dental histories, physical examination, and the results of diagnostic tests.

The role of bioelectronic instruments in documenting and managing temporomandibular disorders

Article Abstract:

Electronic measurements of the jaw muscle's activity at rest and at work may help define the cause of and treat temporomandibular disorders (TMD). TMD involves pain and dysfunction of the temporomandibular (jaw) joint and muscles. Surface electromyography (EMG) was used to record jaw movements and bite positions in 3,681 TMD patients. A subset of 313 patients sought long-term therapy and received an orthotic appliance to move the bite to a better position. Headaches, joint and ear symptoms, and facial and back pain improved after one month of appliance use.

Chondromatosis of the temporomandibular joint: a case report

Article Abstract:

A case is described of a 32-year-old woman who was seen by a maxillofacial for pain in her temporomandibular, or jaw, joint. She believed she had an ear infection and the area around the ear was swollen. An MRI scan showed small oval bodies in the joint. The surgeon used an arthroscope to confirm that she had synovial chondromatosis. This condition is caused by the production of cartilage nodules in joints, usually the knee. The stones were surgically removed.
