| 目的 比较抛光材料的粒度对3种复合树脂粗糙度及表面润湿性的影响。方法 选择3种复合树脂材料,分别为Filtek Z100（A组）,Charisma（B组）和Clearfil AP-X（C组）,采用不同粒度的抛光材料(Sof-LexTMExtra Thin抛光彩碟),随机分组抛光,然后,检测表面粗糙度（Ra）及接触角,并进行统计学分析。结果 随抛光彩碟粒度减小,3种材料的Ra值均逐渐减小,精细粒度抛光组的接触角显著低于3个较粗粒度抛光组（P<0.05）;3种材料在相同抛光材料粒度处理后,Ra显著不同（P<0.05）:A组P<0.05）。结论 复合树脂的表面粗糙度及润湿性与材料种类和抛光材料的粒度相关。 |

| Objective To compare the effects of polishing grits on surface roughness and wettability of three composite resin materials. Methods After Filtek Z100(3M ESPE, America)(group A), Charisma(Her-aes Kulzer, Germany)(group B)and Clearfil AP-X(Kurary, Japan)(group C)cured, these samples were divided into 4 groups to be polished with different polishing grits discs(Sof-LexTM Extra Thin (3M ESPE, St Paul, MN, Amaerica)) at random. Then, surface roughness and contact angle were determined with profilometer and con-tact angle measurement. At last, data were analyzed and compared by SPSS. Results Ra values of three materials gradually decreased with the decrease of polishing grits size, The super fine group (SF) showed the lowest contact angle value than the other coarse grit groups (P<0.05). Using the same polishing grits, Ra values were different ac-cording to materials (P<0.05):group A had higher contact angle value than group B and group C (P<0.05). Conclusions Surface roughness and contace angle of composite resin materi-als were influenced by the grits size of polishing materials. |
