Abstract

A prevalence of temporomandibular disorders(TMD) based on the clinical sign and symptom in 155 patients were investigated. History taking with interview chart and clinical examination were performed. Age and gender of the patients, duration of TMD, location of pain, joint sound, limitation of mouth opening and more detailed diagnostic name were identified. The results of this study were as follows: 1. TMD was more prevalent in female than in male. TMD was the most prevalent at the age of 20s and decreased with age. 2. Acute TMD was more prevalent than chronic one. 3. About ninety percent of TMD patients had pain. Pain had mainly a unilateral origin. Muscle pain was mainly related with the masseter muscle. 4. Joint sound was identified in about fifty-six percent of the TMD patients and unilateral joint sound was more prevalent than bilateral one. 5. Limitation of mouth opening was observed in about forty percent of the TMD patients. 6. In TMD patients, muscle dysfunction was the most prevalent one. In muscle disorders local muscle soreness was the most prevalent one. In joint disorders, capsulitis was the most prevalent one. In muscle-joint disorders, trigger point pain with retrodiscitis was the most prevalent one.
