The case of a patient with bilateral preauricular pain and tinnitus is reported. Minimal relief was obtained with traditional temporomandibular disorders therapy, and complete relief was obtained after endodontic therapy. Pulpal conditions that can refer pain are discussed, and recommendations are made to help practitioners identify a possible pulpal etiology for symptoms and tests of temporomandibular disorders.

Seventeen patients with neuropathic orofacial pain are presented with reference to precipitating events, pain descriptions, response to treatment, and other aspects of their histories and clinical presentation. Stellate ganglion blocks were done on 14 patients. Ten of 14 patients reported temporary relief of pain with stellate ganglion blocks. ⋯ It is argued that sympathetically maintained pain involving orofacial locations does occur and that stellate ganglion blocks may benefit a subgroup of these patients. It is noted that current diagnostic categories are inadequate to describe a subgroup of these patients. New categories are suggested, and further study is recommended.

This study explored psychologic and physiologic factors differentiating patients with temporomandibular disorders (n = 23) from sex-, age-, and weight-matched asymptomatic control subjects. Each subject completed several standard psychologic questionnaires and then underwent two laboratory stressors (mental arithmetic and pressure-pain stimulation). Results indicated that patients with temporomandibular disorders had greater resting respiration rates and reported greater anxiety, sadness, and guilt relative to control subjects. ⋯ There were no differences between patients with temporomandibular disorders and control subjects on pain measures or any other measured variable for the pressure-pain stimulation trial. In addition, there were no differences in electromyography levels between patients with temporomandibular disorders and control subjects. The results are discussed in terms of their implications for the etiology and treatment of this common and debilitating set of disorders.
