摘　　要：目的:了解牙科发光二极管光固化灯应用于患牙备洞树脂充填固化后的临床效果。方法:按纳入标准选择门诊就诊患者患牙160颗,龋损和楔状缺损各80颗。随机分为试验组和对照组,使用牙科树脂材料充填后,实验组应用发光二极管光固化灯固化20sec,对照组应用普通卤光灯固化40sec,打磨抛光;12个月后复诊,评价。结果:楔状缺损实验组有1颗充填物脱落,1颗边缘密合度缺陷,1颗边缘着色,成功率92.1%;对照组有1颗充填物脱落,1颗边缘着色,成功率94.4%;无统计学意义上的差异(P>0.05)。龋损实验组有3例边缘密合度缺陷,2颗边缘着色,成功率87.5%;对照组有2颗边缘密合度缺陷,1颗边缘着色,成功率91.7%;无统计学意义上的差异(P>0.05)。结论:发光二极管光固化灯与普通卤光灯临床效果没有区别,但操作时间更短,使用更为轻巧。Objective： To explore the clinical effects of light-emitting diode curing light in the restoration of cavity by composite resin. Methods： 160 teeth with wedge-shaped defects （80） or caries （80） were selected in clinical patientsthis study. Both of wedge-shaped defects teeth and caries teeth were randomly divided into experimental group or control group. The experimental group were cured with the light-emitting diode curing light （20s）and the control group with halogen light （40s）. 12 months later, index of Modified Ryge Criteria criteria was used to evaluate the clinical effects of curing lights. Results： In wedge-shaped defects teeth, the successful rate of experimental group was 92.1%, and that of control group was 94.4%. The difference was statistically insignificant （P〉0.05）. In caries teeth, the successful rate of experimental group and control group were 87.5% and 91.7% respectively. The difference was statistically insignificant （P 〉0.05）. Conclusion： Compared to halogen dental curing light, LED curing light achieves the same clinical effects, but with the advantage of lesssaves half of the curing time.
