The research of development of reminral ization activator with long term remaining performance on root dentin surface

本研究的目的是评价释氟涂层材料在根面牙本质表面长期滞留的防龋性能。研究结果表明，涂层材料的氟释放量大于现有材料。涂层材料对根面牙本质的再矿化作用（防龋措施）明显高于其他材料。氟化物的应用提高了牙本质与牙科材料之间的粘结强度。然后在牙本质与牙科材料之间的界面上检测氟离子。

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.
