Survey of the Clinical Symptoms of TMD Patients Department of Fixed Prosthodontics, Iwate Medical University Dental Hospital

Abstract

An obvious gender difference of a male to female ratio of 1 to 3 and age distribution, showing a doublecurve peaking in the twenties and forties, were apparent among the patients.The chief complaint of pain in the masticatory muscles tended to increase. Whereas, patients having occlusal problems involving premature contact, interference during movement to the eccentric position, or discrepancy tended to decrease.These two distinctive points were thought to represent the yearly transitional trend of TMD patients in the northern part of the Tohoku region in Japan.
