Abstract

Medical records of 517 TMD (Temporomandibular Disorders) patients were investigated in this research (121 males and 396 females; mean age, 33.3±15.9years). These patients were examined as part of routine procedures at the TMD clinic, Department of Fixed Prosthodontics, Tokushima University Dental Hospital, from September 1989 to September 1996. Items in the basic TMD examination record of our clinic were the chief complaint, anamnesis, clinical history, present observations, radiological observations, diagnosis and treatment plan, etc. From the examination record, we focused on the chief complaint, anamnesis, clinical history, and present observations. The most frequent complaint was temporomandibular joint sound, then pain of temporomandibular joint and jaw muscles, limiting mouth opening. Medical records of 86 TMD patients, of ages from 21 to 25, were compared with 151 dental students of Tokushima University. Moderate and severe teeth attrition, and awareness of nocturnal bruxism, were found in TMD patient more frequently. Overjet of these patients was less than that of dental students.
