Major psychological disorders in acute and chronic TMD: an initial examination.

This study assessed psychological disorders in 50 patients with chronic temporomandibular disorders and 51 patients with acute TMD. The results revealed a significant psychological comorbidity in both groups of patients. Both groups had high rates of psychopathology that exceeded the base rates of the general population. Such findings are in keeping with an integrated biopsychosocial model of TMD, and have significant implications for treatment of these patients.
