Research Abstract

The purpose of this research was to evaluate the fluoride-releasing coating material, which have the performance of long-term remaining on root dentin surface due to caries prevention. The results of this study showed that amount of fluoride release from the coating material was larger than that of current material. Remineralization of root dentin (the measure of caries prevention) by the coating material was indicated more than that of other materials. Fluoride application was made improve bonding strength between dentin and dental material. Then fluoride ion was detected on interface between dentin and dental material.
