Outline of Final Research Achievements

We conducted an exploratory study on the data of various test items and the results of the masticatory ability test of the research subjects. A comparison of the collected masticatory abilities with the individual correlations of the various test items of the study subjects and the mean values showed significant differences between the duration of diabetes and the number of upset teeth and masticatory abilities. Masticatory efficiency was significantly negatively correlated with duration of diabetes and the number of moving teeth and positively correlated with the number of remaining teeth. In addition, a multiple regression analysis was performed on masticatory ability, and items that seemed to affect the masticatory ability of the participants were examined. As a result, masticatory ability was shown to be associated with the number of remaining teeth and diabetic neuropathy.

Academic Significance and Societal Importance of the Research Achievements

本研究の成果から、咀嚼というスコアを用いることで糖尿病患者における食事療法の質の向上を図れる可能性がある。つまり咀嚼のスコアが低い方に対して、歯科医師が介入し咬合治療を行うことで、咀嚼の理由から摂取可能な食事の制限が減少し、栄養バランスも同時に改善することができれば糖尿病の改善につながる可能性が期待できる。また本研究で明らかになった、残っている歯の数および糖尿病性神経障害と咀嚼能力の関係について今後さらに検討することで、糖尿病と歯科に関するより詳細な関係が示される可能性が示唆された。
