OBJECTIVE: This study evaluated the efficacy of a cognitive-behavioral therapy (CBT), including hypnosis, in patients with temporomandibular disorders (TMDs) with muscular diagnosis. STUDY DESIGN: Seventy-two patients (65 women and 7 men with an average age of 39 years) were selected according to the Research Diagnostic Criteria for TMD, and assigned to the experimental group (n = 41), receiving the 6-session CBT program, and the control group (n = 31). All patients received conservative standard treatment for TMD. The assessment included pain variables and psychologic distress. RESULTS: There were significant differences between the groups, the experimental group showing a higher improvement in the variables evaluated. Specifically, 90% of the patients under CBT reported a significant reduction in frequency of pain and 70% in emotional distress. The improvement was stable over time, with no significant differences between posttreatment and 9-month follow-up. CONCLUSIONS: CBT, including hypnosis, significantly improved conservative standard treatment outcome in TMD patients.
