| Outline of Final Research Achievements |
Recently, research has been conducted on how oral function and swallowing function of the elderly people affect general health. The purpose of this study was to clarify the relationship between swallowing function and number of present teeth, occlusal state, and skeletal muscle index in the elderly people living in the community. The number of elderly people who participated in the long-term care prevention project was 236 (88 men: average age 75.9 ± 7.4 years, 148 women: 77.6 ± 6.5 years).
This result suggests that loss of occlusal support in the molar may be associated with decreased swallowing function in community-dwelling elderly women. In addition, it may suggests that the independent elderly maintain a constant Substance P.

| Academic Significance and Societal Importance of the Research Achievements |
本研究では、口腔機能、Substance P（SP)を用いた嚥下機能の評価および全身およびとの関連について明らかにすることで、高齢者の唾液中SP濃度計測による簡便な嚥下機能評価について検討した。自立高齢者において、SP値と反復唾液嚥下テストの関連については有意な傾向を示した。また、自立高齢者は入院患者や要介護者と比較し、一定のSP値を維持している可能性があり、今後は対象に自立高齢者以外に要介護状態の高齢者を加え比較し検討を続けていく必要がある。
