The aim of this study was to compare surface roughness and gloss of resin composites polished using different polishing systems. Five resin composites were investigated: Filtek Silorane (FS), IPS Empress Direct (IP), Clearfil Majesty Posterior (CM), Premise (PM), and Estelite Sigma (ES). Twenty-five disk specimens were prepared from each material, divided into five groups, each polished with one of the following methods: Opti1Step (OS), OptiDisc (OD), Kenda CGI (KD), Pogo (PG), or metallurgical polishing (ML). Gloss and roughness parameters (Sa, Sz, Sq, and St) were evaluated by 60°-angle glossimetry and white-light interferometric profilometry. Two-way analysis of variance was used to detect differences in different materials and polishing techniques. Regression and correlation analyses were performed to examine correlations between roughness and gloss. Significant differences in roughness parameters and gloss were found according to the material, type of polishing, and material/polishing technique (p< 0.05). The highest roughness was recorded when KD was used (Sa: 581.8 [62.1] for FS/KD, Sq: 748.7 [55.6] for FS/KD, Sz: 17.7 [2.7] for CM/KD, and St: 24.6 [6.8] for FS/KD), while the lowest was recorded after ML (Sa: 133.6 [68.9] for PM/ML, Sq: 256.5 [53.5] for ES/ML, Sz: 4.0 [1.3] for ES/ML, and St: 7.1 [0.7] for ES/ML). The highest gloss was recorded for PM/ML (88.4 [2.3]) and lowest for FS/KD (30.3 [5.7]). All roughness parameters were significantly correlated with gloss (r= 0.871, 0.846, 0.713, and 0.707 for Sa, Sq, Sz, St, and gloss, respectively). It was concluded that the polishing procedure and the type of composite can have significant impacts on surface roughness and gloss of resin composites.
本研究旨在比较使用不同抛光系统抛光的树脂复合材料的表面粗糙度和光泽度。研究了五种树脂复合材料：Filtek Silorane (FS)、IPS Empress Direct (IP)、Clearfil Majesty Posterior (CM)、Premise (PM)和 Estelite Sigma (ES)。从每种材料中制备了 25 个圆盘试件，分为五组，每组用以下方法之一抛光：Opti1Step (OS)、OptiDisc (OD)、Kenda CGI (KD)、Pogo (PG)或金相抛光 (ML)。通过 60°角光泽度计和白光干涉轮廓仪评估光泽度和粗糙度参数（Sa、Sz、Sq 和 St）。采用双向方差分析检测不同材料和抛光技术之间的差异。进行回归和相关性分析以检查粗糙度和光泽度之间的相关性。根据材料、抛光类型以及材料/抛光技术，发现粗糙度和光泽度参数存在显著差异（p<0.05）。使用 KD 时记录到最高的粗糙度（FS/KD 为 Sa：581.8 [62.1]、Sq：748.7 [55.6]、Sz：17.7 [2.7] 和 St：24.6 [6.8]），而使用 ML 时记录到最低的粗糙度（PM/ML 为 Sa：133.6 [68.9]、Sq：256.5 [53.5]、Sz：4.0 [1.3] 和 St：7.1 [0.7]）。记录到最高的光泽度为 PM/ML（88.4 [2.3]），最低的为 FS/KD（30.3 [5.7]）。所有粗糙度参数均与光泽度显著相关（Sa、Sq、Sz、St 和光泽度的 r 值分别为 0.871、0.846、0.713 和 0.707）。结论是，抛光程序和复合材料的类型会对树脂复合材料的表面粗糙度和光泽度产生重大影响。
