      【摘要】 目的 比较制备短斜面、凹斜面两种洞缘斜配合FiltekA350流体树脂修复楔状缺损后一年内的脱落
率。方法 收集2011年7月至2012年7月来我科门诊就诊的楔状缺损患者58例，患牙106颗，采用随机数字表将
患者随机分为短斜面组和凹斜面组，每组53颗，分别在釉质合面制备短斜面、凹斜面后流体树脂进行充填，观察充
填治疗一年内的脱落率。结果 凹斜面组与短斜面组患者修复1年内充填体的脱落率分别为4.3% (2/46)和8.0%
(4/50)，凹斜面组的脱落率低于短斜面组，但差异无统计学意义(P>0.05)。结论 凹斜面组配合流体树脂修复楔状
缺损，相比短斜面组，修复一年内充填体的脱落率更低。

【Abstract】 Objective To investigate the expulsion rate of two restoring methods, the short bevel and the hol-
low-ground bevel, using the flowable composite to repair the wedged-shaped defects, within one year after restoring.
Methods A total of 58 cases of patients with 106 teeth of wedge-shaped defects, who admitted to Department of Stoma-
tology of our hospital from July 2011 to July 2012, were randomly divided into two groups with 53 teeth in each group.
After preparing two types of cavities, the short bevel and the hollow-ground bevel, and using the flowable composite to
repair the wedged-shaped defects, expulsion rates of two restoring methods during one year after restoring were investi-
gated. Results The expulsion rates of the hollow-ground and the short bevel are respectively 8.0% and 4.3%. There
was no significant difference between two bevels by using the flowable composite to restore the defect in the expulsion
rate. Conclusion Compared with the short bevel, the hollow-ground by using the flowable composite to restore the de-
fect has the lower expulsion rate within one year after restoring.
