Effects of intraoral appliance and biofeedback/stress management alone and in combination in treating pain and depression in patients with temporomandibular disorders.
To assess the differential efficacy of two commonly used treatments for temporomandibular disorders (TMD), intraoral appliances (IAs) and biofeedback (BF), separately and in combination, two studies were conducted. The first study directly compared IA treatment, a combination of biofeedback and stress management (BF/SM), and a waiting list control group in a sample of 80 TMD patients. Both treatments were determined to be equally credible to patients, ruling out this potential threat to the validity of the results obtained. The results demonstrated that the IA treatment was more effective than the BF/SM treatment in reducing pain after treatment, but at a 6-month follow-up the IA group significantly relapsed, especially in depression, whereas the BF/SM maintained improvements on both pain and depression and continued to improve. The second study examined the combination of IA and BF/SM in a sample of 30 TMD patients. The results of this study demonstrated that the combined treatment approach was more effective than either of the single treatments alone, particularly in pain reduction, at the 6-month follow-up. These results support the importance of using both dental and psychologic treatments to successfully treat TMD patients if treatment gains are to be maintained.
