| Outline of Final Research Achievements |
At present, the objective diagnostic method for tooth wear has not been established. Therefore, we constructed a tooth wear diagnostic model by using oral three-dimensional data and local OCT three-dimensional data. That is to say, the progress position of the defect is detected and quantified from the difference of the three-dimensional data, and the progress speed is calculated. We also developed a non-invasive method to evaluate tooth abrasion using OCT as a tooth wear diagnostic model by quantifying residual tooth mass and integrating these data.

| Academic Significance and Societal Importance of the Research Achievements |
tooth wearは，齲蝕，歯周病に次ぐ第三の口腔硬組織疾患として，細菌が関与することなく歯の損耗を生じる病態の総称である。近年，国民の口腔衛生状態改善による残存歯牙の増加に伴い，その罹患者も増加する傾向にある。多くの因子が相互に作用することによって生じるtooth wearは，原因の特定および予後の判断が困難とされてきた。咬耗症や酸蝕症などの，本研究によって検査方法を確立し，質の高いデータが収集可能となる。将来的に，検査結果から多因子性疾患であるtooth wearの病態解明および，妥当性の高い治療法の提案が可能となる。
