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.
