Outline of Final Research Achievements

In this research, we have succeeded in analyzing the difference of tooth etchant effectiveness by comparing to 3 types of tooth etchants. Etchant of organic acids showed high bonding performance on both enamel surface and dentin surface. This research demonstrated that etchant of organic acids is alternative to phosphoric acid etchant.

Academic Significance and Societal Importance of the Research Achievements

「リン酸と1液性セルフエッチング材を用いたユニバーサル接着システム」において、象牙質との接着界面の耐酸性に問題が生じることを報告していた。本研究成果より、セルフエッチングシステムを用いる際には、象牙質接着に影響を及ぼすリン酸の代わりに有機酸を用いることによってこの問題の解決できることが示唆された点が学術的意義としてあげられる。本研究結果は、そのまま臨床に反映させることが可能であり日々行われているう蝕(むし歯)に対する歯科治療の質を向上させる点が社会的意義としてあげられる。
