| Outline of Final Research Achievements |
By investigating the decline in oral function in a large number of people at different ages, we will clarify the mean value and distribution for each age group, and establish the age of oral function. We aim to add age difference, sex difference, and simplicity to the diagnostic criteria, and to present an early indication of the age of oral function by synthesizing each of the examination items. Seven tests for oral hypofunction (1)poor oral hygiene, 2) oral driness, 3) reduced occlusal force, 4) decreased tongue-lip motor function, 5) decreace tongue pressure, 6) decreased masticatory function, and 7) Deterioration of swallowing function) were performed. Based on the approximate straight lines obtained, the age of each oral function was calculated. From the oral functional age calculated for each function, the weighting of each item was determined based on multivariate analysis data with age as the objective variable, and the overall oral functional age was calculated.

| Academic Significance and Societal Importance of the Research Achievements |
超高齢社会の日本において，平均寿命と健康寿命の乖離が問題となっている．健康寿命を延伸するためには，フレイルの予防，その始まりと言われるオーラルフレイルの予防が重要とされる．口腔機能低下症は７つの検査①口腔不潔，②口腔乾燥，③咬合力低下，④舌口唇運動機能低下，⑤低舌圧，⑥咀嚼機能低下，⑦嚥下機能低下からなるものであり，基準値は年齢，性別にかかわらず一定である．年齢，性差事に口腔機能年齢を確立することで，管理へのモチベーション向上が可能となる．
