Globally, tinnitus affects between 14 and 32% of the population, occurring at any age of both sexes and increasing with age. The most significant otologic symptoms such as ear pain, tinnitus, dizziness, and hearing loss in clinical practice are often associated with disorders of the nearby temporomandibular joint. Dental practice often has abnormalities of the temporomandibular joint, with an incidence of 18–27% in the population. These disorders may be associated with trauma, injury or dislocation in the disc of the temporomandibular joint, excessive strain on the jaw muscles (e.g., bruxism), arthritis or malocclusion. Symptoms include pain in the jaw and/or face, difficulty opening the jaw and chewing, and sounds when opening the mouth (for example, when talking or chewing). The incidence of tinnitus in subjects with temporomandibular disorders is up to 60%. This report traces the link between tinnitus and temporomandibular disorders.
