The demand for esthetic and natural-looking restoration has been extended to the restoration of the posterior teeth in recent years. The development of resin cement for ceramic materials have enable esthetic posterior inlay restoration. However, it was reported that the wear loss of resin cement was occur and it become cause of the trouble. Hence, the improvement of the resin cement, especially, adhesion of resin to tooth substrates was needed.The purpose of this study was to investigate the effect of the initiator in self-etching primer on the adhesiveness of resin materials to tooth. Two experimental self-etching primer was prepared. the one is aqueous solution of amino acid derivatives. An amine acid derivative was used as adhesion monomer and initiator. The other is the mixture of mareic acid and HEMA.The tensile bond strength promoted by amino acid derivative (3.4MPa) was higher than that promoted by mareic acid-HEMA mixture. (1.2MPa) The conversion rate of resin was high when used with conbination of amino acid derivatives and N-phenylglycine. The rate was increased with the time.We concluded that amino acid derivatives was effective for initiator and promoter in the self etching primer

近年来，对美观和自然修复的需求已扩展到后牙的修复。用于陶瓷材料的树脂水门汀的开发使得美观的后嵌体修复成为可能。然而，据报道，树脂水泥发生磨损，成为故障的原因。因此，需要对树脂水门汀进行改进，特别是树脂与牙齿基质的粘合力。本研究的目的是探讨自酸蚀底漆中引发剂对树脂材料与牙齿粘合力的影响。制备了两种实验性自蚀底漆。一是氨基酸衍生物的水溶液。使用氨基酸衍生物作为粘合单体和引发剂。另一种是马来酸和HEMA的混合物。氨基酸衍生物促进的拉伸粘合强度(3.4MPa)高于马来酸-HEMA混合物促进的拉伸粘合强度。 (1.2MPa) 氨基酸衍生物与N-苯基甘氨酸并用，树脂转化率高。速率随时间增加。我们得出结论，氨基酸衍生物对于自蚀刻底漆中的引发剂和促进剂是有效的
