摘要: 复合树脂是口腔临床工作中重要的材料之一,主要应用于牙体缺损的修复,粘接等方面。但是其内含的单体之一双酚A-双甲基丙烯酸缩水甘油酯(bisphenol A diglycidylmethacrylate, bisGMA)很容易被来自细菌以及唾液中的酯酶降解,产生副产物双羟丙氧基苯基丙烷(Bishydroxypropoxyphenyl propane,bisHPPP)进而影响患者修复体的使用寿命,这就称为复合树脂的生物降解。因此,本文系统地就复合树脂生物降解的原因,机制,在不同口腔材料中的应用以及如何避免进行综述,为临床中使用复合树脂提供指导。

Abstract: Composite resins is one of the important materials in stomatology which mainly applied in rest-oration of tooth defect、dental adhesives and so forth. However, it is fact that bisphenol A diglycidylmeth-acrylate (bisGMA) existed in composite resins can be biodegraded by esterase from bacteria and saliva, releasing the by-product named bishydroxypropoxyphenyl propane (bisHPPP), thus decreasing the life span of restoration. The article provides reasons, mechanism of composite resins biodegradation, rewiewing application in the different material and giving method to alleviate biodegradation, which will provide help in the use of composite resins.
