| Outline of Final Research Achievements |
This study aimed to develop the methods to assess pH change at the interface between material or tooth and bacteria continuously under the same kind of conditions as an oral microenvironment in vitro. The fluoride releasing materials and the silver diamine fluoride coated tooth inhibited pH fall at the interface between material/tooth and bacteria. The degree of inhibition of pH fall seemed to correspond to the amounts of fluoride and silver detected, suggesting that the fluoride and silver released from these materials inhibited pH fall.

| Academic Significance and Societal Importance of the Research Achievements |
本研究の成果は、歯面や歯根面の詳細な脱灰メカニズムの解明に寄与するものであり、齲蝕の予防・治療に効果のある歯科材料・食品・薬剤等の評価や開発に応用が可能なことに加えて、より精度の高い齲蝕の基礎研究・臨床研究への展開が期待できる。
