SOFT-START光聚合模式对复合树脂充填效果的影响

Clinical evaluation of SOFT-START photopolymerization mode on composite restorations

目的:研究两种光聚合模式对复合树脂充填的临床效果。方法:选取20例患者,共84颗楔状缺损,随机分为两组,每组42颗。分别使用软启动(SOFT-START)光聚合模式和传统高光强光聚合模式进行Z350复合树脂充填。另一名医师分别在修复后1周、3个月、6个月,12个月按照改良的美国公共卫生机构直接修复评价标准(USPHS)进行盲法评价。结果:在12个月的随访期内,SOFT-START光聚合模式的修复成功率优于传统高光强光聚合模式(P<0.05)。结论:光聚合模式对复合树脂的充填效果有影响,SOFT-START光聚合模式的修复效果优于传统高光强光聚合模式。

Objective To evaluate the clinical performances of two kinds of photopolymerization modes on composite restorations. Methods Eighty-four restorations were made by one operator for 20 patients.The resin composite Z350 were used to restore the teeth for SOFT-START photopolymerization mode and conventional photopolymerization mode respectively.The evaluation was performed by another practitioner according to modified United States Public Health Service （USPHS） criteria at one week,six months,twelve months. Results After twelve months the overall success rate of the two groups（SOFT-START photopolymerization mode and conventional photopolymerization mode） showed differences （P〈0.05）. Conclusion The restorations by SOFT- START photopolymerization mode are superior to that by conventional photopolymerization mode.
