Outline of Final Research Achievements

The purpose of this study was to clarify risk factors for intractable symptoms of temporomandibular joint disorders, but the reliability of magnetic resonance (MR) image evaluation of temporomandibular joint morphology, an anatomical factor, was not sufficient. Therefore, we established MR image interpretation criteria that can evaluate the tissues that compose the temporomandibular joint and examined the reliability of temporomandibular joint MR image evaluation using the interpretation criteria. Using the most frequent results from three examiners, it was shown that the interpretation criteria have sufficient reliability.

Academic Significance and Societal Importance of the Research Achievements

これまでMR画像の読影基準には種々のものがあるが，それらの中で信頼性の検討がなされているものは少ない。信頼性の低い読影基準に基づいた研究結果は，当然のようにその妥当性，普遍性に疑問が残る。今後，MR画像を用いた顎関節症の長期予後調査を計画するうえで，信頼性の高い本読影基準を用いることは質の高い研究結果を導くために必要不可欠と言える。
