14 patients, whose were attacked pain dysfunction syndrome of temporomandibular joint in Dental College Infirmary, Seoul National University from June 1970 to Dec. 1971, were examined regarding to clinical observation and electromyographical analysis. This paper established the followings: 1. Especially young female was more frequently attacked by pain dysfunction syndrome of Temporomandibular joint. 2. It is suggested that most of joint pain was occurred initially in opening mouth and forcible bite, and left side is more attacked than right side. 3. It was possible that this dysfunction can be occurred by open-bite, premature contact and ill-fitting prosthetic restoration. 4. Hoby, habit and bruxism as causal factors are not markedly related with this dysfunction. 5. Pain attacked regions, in most patients, are preauricular, joint itself, infra-auricular, cervical and external auditory meatus region. 6.
