摘　　要：目的:分析渗透树脂治疗正畸后白垩斑的美学效果并与微研磨法进行比较。方法:筛选符合纳入排除标准的正畸后白垩斑患者10名(66颗患牙),采用自身对照设计,将不同区域患牙随机分为渗透树脂组和微研磨组(n=33)。处理后采用口内照相和图像软件分析治疗前(T0)、1周复诊(T2)、3月复诊(T3)时患牙的病损面积及唇面总面积,计算出病损面积比(R值)及治疗有效率(SR值),比较2种方法治疗正畸后白垩斑的牙齿美学恢复情况。采用重复测量单因素方差分析对结果进行统计。结果:渗透树脂可以显著减患牙小白垩斑病损面积(P<0.05),且3个月内保持稳定;渗透树脂组和微研磨组治疗有效率分别为88.68%和64.67%(P<0.05)。结论:渗透树脂改善正畸后白垩斑病损的美观效果优于微研磨法。Objective：To evaluate the effects of resin infiltration in the treatment of post-orthodontic white spot lesions （WSLs）and compare it with microabrasion.Methods：1 0 subjects with 66 teeth with noncavitated and unrestored WSLs after multibracket treatment were recruited.A simple randomized,split-mouth and controlled design was used to allocate WSLs to the resin infiltration and micro-abrasion groups（n =33）.The area of the WSLs were measured photographically by using image analysis software before treatment （T0）,1 week（T2）and 3 months（T3）after treatment.Data were analyzed with multifactorial analysis of the variances with repeated measures at an a level of 5% and a power of 80%.Results：The area of the white spot lesions（R）decreased significantly in both groups（P 〈0.05）.At T3 the success rate of resin infiltration group（88.68%）was significantly higher than that of microabrasion group （64.67%）（P 〈0.05）.Conclusion：Resin infiltration is more effective than microabrasion in the treatment of post-orthodontic WSLs.
