| Outline of Final Research Achievements |
The effect of adding an activator which imparts chemical polymerization to light-curing bonding materials on root canal dentin adhesion was evaluated by bonding effectiveness. In addition, a new method for evaluating adhesion in detail by nondestructive observation under μCT to observe the gap at the bonding interface were established.

| Academic Significance and Societal Importance of the Research Achievements |
本研究で使用した重合促進剤は新規の材料であったことから，これを根管象牙質に応用した報告は数少ない．
本研究から化学重合性が根管象牙質に高い接着性を示すことが明らかになったことにより，臨床におけるレジン支台築造法に関するガイドライン作成の一助になると考えられる．また，μCTを駆使した接着性評価法を確立したことで，歯科材料研究がより発展することが考えられる．
