| Outline of Final Research Achievements |
67 subjects (15 males, 52 females, average age at first visit 39.6 ± 16.4 years) of the all 338 subjects agreed to this study and underwent follow-up. The average elapsed period since the first visit was 12.2 +/- 1.1 years. 7 subjects with incomplete data were excluded, and we analyzed 60 subjects in this experiment. Comparing the mouth opening range at the time of the first visit to the follow-up survey, the mouth opening range increased respectively. There was no significant difference in the mouth opening range between the pathological classifications. Regarding the degree of pain and associated symptoms, the pain in the temporomandibular joint was significantly reduced at rest time and during functioning. On the other hand, there was no significant difference in the degree of headache, neck pain, and stiff shoulders.

| Academic Significance and Societal Importance of the Research Achievements |
本研究の結果，多くの患者で，顎関節の良い意味での適応変化が10年後には生ずると説明ができるようになれば，臨床上患者に与える安堵も大きい。また，不必要な過剰治療を行うことも減ずることができる。本研究のような予後のデータは，真の意味での病態把握と治療方針の決定に寄与できる可能性があると考えられる。
