Dentists' ability to detect psychological problems in patients with temporomandibular disorders and chronic pain.

Do patients with temporomandibular disorders (TMD) have significant psychosocial problems? Research efforts have sought to determine if these problems exist, and if so, how they influence treatment outcome. Even when psychosocial factors do influence treatment outcome, identifying them by formal psychological tests can be time consuming and costly. Dentists' impressions of the psychological status of these patients were tested to determine if they are an effective method for screening psychological factors thought to influence treatment outcome. The results suggested that a screening procedure based on dentists' impressions from an initial examination do not adequately identify psychological problems in patients with TMD.
