The finishing and polishing of composite materials affect the restoration lifespan. The market shows a variety of finishing and polishing procedures and the choice among them is conditioned by different factors such as the resulting surface roughness. In the present study, 156 samples were realized with three composite materials, -microfilled, nanofilled and silorane-, and treated with different finishing and polishing procedures. Profilometric analyses were carried out on the samples' surface, the measured roughness values were submitted to statistical analysis. A complete factorial plan was drawn up and two-way analysis of variance (ANOVA) was carried out to investigate whether the following factors affect the values of roughness: (i) material; (ii) polishing/finishing procedure. Tukey post-hoc test was also conducted to evaluate any statistically significant differences between the material/procedure combinations. The results show that the tested materials do not affect the resulting surface quality but roughness values depend on the finishing/polishing procedure adopted. The procedures that involve: (a) the finishing with medium Sof-Lex discs and (b) the finishing with two tungsten carbide multi-blade milling cutters Q series and UF series are those that allow the lowest values of roughness to be obtained.
复合材料的修整和抛光会影响修复体的使用寿命。市场上有各种各样的修整和抛光程序，而在这些程序中的选择受不同因素制约，比如最终的表面粗糙度。在本研究中，用三种复合材料（微填料、纳米填料和硅氧烷）制作了156个样本，并用不同的修整和抛光程序进行处理。对样本表面进行轮廓测量分析，将测得的粗糙度值进行统计分析。制定了一个完全析因计划，并进行了双向方差分析（ANOVA），以研究以下因素是否会影响粗糙度值：（i）材料；（ii）抛光/修整程序。还进行了Tukey事后检验，以评估材料/程序组合之间的任何统计学显著差异。结果表明，所测试的材料不会影响最终的表面质量，但粗糙度值取决于所采用的修整/抛光程序。涉及以下操作的程序能够获得最低的粗糙度值：（a）用中等粒度的Sof-Lex盘进行修整；（b）用两把碳化钨多刃铣刀Q系列和UF系列进行修整。
