摘　　要：目的 ：评价3种抛光方法对楔状缺损树脂修复后的临床疗效。方法 ：150例需要双侧下颌第一前磨牙楔状缺损治疗的患者随机分为Sof-lex discs系统抛光组、Super-snap系统抛光组和金刚砂抛光车针修形＋橡皮杯抛光组,每组患者各50例,各100颗患牙。各组患者均使用3M Z350纳米复合树脂对楔状缺损进行充填,修复完成后使用3种抛光方法进行抛光。经过半年、1 a、2 a复查后,采用USPH＆Ryge评估标准进行评价,采用SPSS17.0软件包对数据进行χ^2检验。结果：复合树脂经过3种抛光方法抛光后,继发龋、边缘密合性、边缘着色、表面粗糙度、色泽匹配、磨耗、牙龈健康状况在半年和1a后的差异无显著性。2a后3组比较,继发龋、边缘密合性、边缘着色、磨耗、色泽匹配有显著差异,Sof-lex discs系统抛光组、Super-snap系统抛光组显著优于金刚砂抛光车针修形＋橡皮杯抛光组,其余各项无显著差异。结论：在楔状缺损复合树脂充填治疗后,使用Sof-lex discs系统和Super-snap系统抛光,能减少术后继发龋、边缘着色和磨耗发生,维持树脂边缘密合,值得临床推广使用。PURPOSE： To evaluate the clinical effect of 3 polishing methods on resin composite restoration in filling wedge-shaped defect. METHODS： One hundred and fifty patients with wedge-shaped defects were randomly divided into 3 groups. After being filled with Nano composite resin（FILTEK Z350,3M）, restorations in group 1 were polished with Soflex discs system, restorations in group 2 were polished with Super-snap system and group 3 with diamond bur and rubber cup. Restorations in each group were reexamined and assessed utilizing standards of USPHRyge after 0.5, 1 and 2 a.Chi-square test was performed using SPSS17.0 software package. RESULTS： No significant difference of secondary decay, marginal adaption, marginal staining, surface roughness, colour matching, wearing and gingival condition among 3 groups was found after 0.5 a and 1 a. Restorations in group 1 and group 2 showed better performance with regards to secondary decay, marginal adaption, marginal staining, wearing and color matching than group 3 after 2 years of restoration. CONCLUSIONS： Sof-lex discs and Super-snap polishing system after composite filling of wedge-shaped defect was effective in reducing secondary decay, marginal staining and wearing, as well as in maintaining the marginal adaption, which is worthy of wide clinical application.
