| Outline of Final Research Achievements |
This study aims to develop a new "high-functional tooth protection restorative material" with a focus on strengthening tooth structure, focusing on various trace metal effects that are effective in remineralising tooth structure, as well as tooth adhesive technology with excellent durability, in order to actively prevent the progression of microcracks or tooth wear. Development of a new "high-functional dentin-protecting restorative material" is the aim of this project. Therefore, a bioactive glass filler was used to investigate its effect on remineralization. The results of the present experiments suggest that the remineralising effect of glass fillers containing Zn ions may enable active prevention of the progression of microcracks or tooth wear. In other words, it was suggested that Zn ions have a remineralization effect on tooth structure and that the application of Zn ions may lead to the development of next-generation restorative systems.

本研究の目的は，マイクロクラックおよびこれを起点として進行するtooth wearを接着技術とともに積極的な再石灰化を促進する微量元素作用を応用した“高機能歯質プロテクト修復材”を開発することにあり，これが学術的独自性とともに創造性である。これによって，超高齢社会の急速な進行に伴って増加する歯の損耗を予防する臨床術式が確立するとともに，口腔内における健康の増進という日本国民の医療経済面からも意義が高い研究であり，国民の健康におけるQOLの向上にも必ずや貢献するものと期待される
