The purpose of this study was to investigate the influence of one-step polishing systems on the surface roughness of different flowable composites and a microhybrid composite. A total of 120 disks were fabricated and divided into six groups according to the different composite restorative materials tested (n = 20). Each group was further divided into four subgroups according to the polishing system (n = 5). For the control group, samples were left undisturbed after removal of Mylar strip. For the other three subgroups, samples were polished with PoGo, OptraPol, or Sof-Lex disks. Surface roughness was determined using a profilometer and observed under scanning electron microscope (SEM). Data were analyzed by one-way ANOVA and Duncan's multiple range test. For Tetric Flow, Grandio Flow, Filtek Supreme XT Flow, and Admira Flow, their lowest surface roughness values were obtained in Mylar Strip and PoGo groups. For Compoglass Flow, there were no significant differences between Mylar Strip, PoGo, and OptraPol. For Filtek Z250, the lowest surface roughness value was obtained with Mylar Strip. In light of the surface roughness results obtained, one-step polishing systems seemed to be a good choice for polishing flowable composites.
本研究的目的是调查一步法抛光系统对不同可流动复合树脂和一种微混合复合树脂表面粗糙度的影响。共制作了120个圆盘，并根据测试的不同复合修复材料分为六组（n = 20）。每组再根据抛光系统进一步分为四个亚组（n = 5）。对照组在去除聚酯薄膜条后不进行处理。对于其他三个亚组，样品分别用PoGo、OptraPol或Sof-Lex圆盘进行抛光。使用轮廓仪测定表面粗糙度，并在扫描电子显微镜（SEM）下观察。数据采用单因素方差分析和邓肯多重极差检验进行分析。对于Tetric Flow、Grandio Flow、Filtek Supreme XT Flow和Admira Flow，在聚酯薄膜条和PoGo组中获得了最低的表面粗糙度值。对于Compoglass Flow，聚酯薄膜条、PoGo和OptraPol之间没有显著差异。对于Filtek Z250，在聚酯薄膜条组中获得了最低的表面粗糙度值。根据所获得的表面粗糙度结果，一步法抛光系统似乎是抛光可流动复合树脂的一个不错选择。
