摘要： 目的评价3种抛光方法对2种复合树脂边缘微渗漏的影响。方法选择80颗离体恒前磨牙,在每颗牙的颊侧颈部釉-牙骨质交界处用高速涡轮机制备盒形单面洞,长和宽均为3 mm,洞深2 mm。使用3M Z350树脂和3M Z250树脂各充填40颗牙。按照充填材料不同,随机分为不抛光组、Sof-lex discs抛光系统组、Super-snap抛光系统组和金刚砂抛光车针修形后再用橡皮杯抛光组。实验样本冷热循环后,在2%亚甲基蓝溶液中浸泡 24 h,沿牙体长轴将充填体正中颊舌向纵行剖开,立体显微镜（×40）下观察剖面,采用Spot 4.6图像分析软件测量渗漏深度。采用 SPSS 17.0 软件包对各组的微渗漏程度和深度分别进行Mann-Whitney U 检验和Kroskal-Walis秩和检验。结果3M Z350各组的边缘微渗漏深度分别为（0.655±0.486）、（0.626±0.497）、（0.634±0.345）和（0.875±0.283） mm。3M Z250各组的边缘微渗漏深度分别为（0.785±0.553） mm、（0.763±0.491） mm、（0.789±0.308）mm和（0.942±0.318） mm。2种树脂充填后,3种抛光方法树脂边缘微渗漏程度和深度均有显著差异（P<0.05）。结论Sof-lex discs抛光系统、Super-snap抛光系统对复合树脂修复体边缘渗漏无显著影响。

Abstract: PURPOSE: To evaluate the effect of different polishing methods on microleakage of different resin composite restorations (Filtek Z350 and Filtek Z250). METHODS: Standardized preparations (the box-type cavities, 3 mm in length and width,2 mm in depth) were prepared at the cemento-enamel junction on buccal surface of 80 premolars. They were randomly divided into 2 groups, and restored with composites( Filtek Z350 or Filtek Z250). Based on polishing methods, the specimens of each group were randomly classified into 4 subgroups: no polishing, polishing with Sof-lex discs, polishing with Super-snap discs and polishing with diamond burs. After thermal circulation (2000 times, 5-55℃) and soaked for 24 hours in 2% methyl blue solution, the specimens were cut through the midline of the restoration, the microleakage at the occlusal margin and the gingival margin were observed under a stereomicroscope and the leakage depth was measured with Spot version 4.6 software package. The microleakage width and microleakage depth of different groups were analyzed with SPSS 17.0 software package for Mann -Whitney U test and Kruskal - Wallis test. RESULTS: The microleakage depth of Filtek Z350 groups was (0.655±0.486) mm,（0.626±0.497） mm,(0.634±0.345) mm and（0.875±0.283）mm, respectively. The microleakage depth of Filtek Z250 groups was (0.785±0.553) mm、(0.763±0.491) mm,(0.789±0.308) mm and (0.942±0.318) mm. The microleakage depth of specimens polishing with diamond burs was significantly deeper than that of other groups. There was no significant difference among specimens with no polishing, polishing with Sof-lex discs and polishing with Super-snap discs. CONCLUSIONS: The polishing system of Sof-lex discs and Super-snap discs have no significant influence on microleakage of resin composite restorations.
