摘　　要：光聚充填复合树脂是牙齿修复的主要原料之一,在临床使用中,树脂中有机基质分子上碳碳双键的聚合转化率决定着修复的效果和树脂在口腔中的使用寿命。光聚转化率是树脂性能的主要评价指标之一,因此,在研究和使用过程中,树脂光聚转化率的测定十分重要。确定光聚充填复合树脂转化率的方法有多种,目前主要是采用仪器分析的方法。基于傅里叶变换红外光谱(FT-IR)、傅里叶变换拉曼光谱(FT-Raman)、近红外光谱(NIR)、差热分析(DTA)、核磁共振(NMR)和高效液相色谱(HPLC)等仪器在牙科充填复合树脂光聚转化率测定方面的应用,介绍牙科充填复合树脂光聚转化率的测定方法,并分析了各种方法的特点。Light polymerization filling composite resin is one of the main raw materials for dental restoration.In the course of clinical application,the effect of repair and the life of the resin in the oral cavity are dominated by the polymerization conversion rate of the carbon double bond an matrix molecules in the resin.The photopolymerization conversion rate is one of the main evaluation indexes of resin properties.Therefore,in the process of research and application,it is very important to measure the conversion of resin.There are many ways to determine the conversion rate of the composite resin.At present,instrumental analysis is a common method to determine the conversion of resin.This review introduces the application of Fourier transform infrared spectroscopy(FT-IR),Fourier transform Raman spectroscopy(FT-Raman),near infrared spectroscopy(NIR),differential thermal analysis(DTA),nuclear magnetic resonance(NMR),high performance liquid chromatography(HPLC)and other methods in the determination of the optical conversion of dental filling composite resin.The characteristics of various methods are also analyzed.
