Abstract
In order to evaluate and compare the effects of biofeedback and occlusal splint therapy on mandibular dysfunction, 30 patients were randomly divided into 2 treatment groups. The patients were women aged 20-40 yr without any obvious organic reasons for their symptoms. There were no significant differences between the 2 groups before the start of treatment with respect to signs and symptoms of mandibular dysfunction. One group used full coverage splints at night for 6 wk. The other group received biofeedback training up to 6 times, 30 min/session. One mo. after completion of the therapy the patients were re-examined. Both groups showed a significant reduction in symptoms, both subjectively and clinically. No significant differences between the groups were found. The 2 treatments were thus equally effective in the short-term perspective in patients with signs and symptoms of mandibular dysfunction.
