Temporomandibular disorder: A practical guide for dental practitioners in diagnosis and management

Temporomandibular disorders (TMD) encompass pain/dysfunction of the masticatory musculature and the temporomandibular joints (TMJ). Typical symptoms may be pain, limited jaw movement or joint noises during jaw movement. TMD can impact on the person’s quality of life and be difficult to manage. The incidence of TMD is similar between men and women; however, women are four times as likely to seek treatment and have greater pain sensitivity. TMD is more likely to persist in women. Bruxism and TMD can exist independently. Signs of bruxism include cracked teeth, failed restorations, chipping of incisal edges, wear facets, mobile teeth, muscle hypertrophy and scalloping of the lateral border of the tongue.
The articulation of the condylar process of the neck of the mandible with the glenoid fossa of the temporal bone forms the bony part. The two joint cavities are formed by the articulating disc and surrounded by the joint capsule. The disc of the TMJ is made of hyaline cartilage inside and lined by fibrous cartilage, which is different from discs in other joints. Bony and disc surfaces are lined with synovial membrane. Muscles and ligaments are attached to the joint capsule, neck of the condyle and body of the mandible. The two TMJ cannot function independently of each other. No other joints in the body function in such a way. Movement of the TMJs is limited by the anatomy of the muscles and the occlusal relationship of the dentition.
