This study was performed with the purpose of investigating electromyographic (EMG) activity of the anterior temporalis and masseter muscles in edentulous patient with trigeminal neuralgia (TN), before and after treatments with carbamazepine and oral rehabilitation with sliding plates on complete dentures. Patients with trigeminal neuralgia may have concomitant dental problems and it may contribute to decrease the quality of life for these patients. The patient was a complete dentures wearer for at least 08 years. EMG recordings were made before treatment with carbamazepine and oral rehabilitation, after insertion of new complete dentures and also after using these prostheses at the thirty days and 8th month using computerized electromyography MyoSystem-Br1. EMG evaluations of the muscles were performed under the following clinical conditions: rest position, right and left laterality, protrusion, clenching and chewing dried grapes. The results showed remission of muscular soreness, reduced neuralgic pain and balanced means value of EMG activity compared with initial values. Carbamazepine was an important recourse to control neuralgic pain and complete dentures with sliding plates contributed to balance of the masticatory muscles activity.
