CLINICALLY, COMPOSITE RESINS can be polished to a smooth surface at the time of placement using a variety of polishing methods. Subsequently maintaining the finish on recalls needs to be evaluated. The purpose of this investigation was to compare surface textures of a small particle composite resin (average particle size 5 microns) after polishing with prophylaxis and polishing pastes. Each specimen of the small particle composite resin, PrismaFil, was finished and polished to a smooth surface with Soflex discs. This was the control polish. The specimens were then polished with a rotating rubber prophylaxis cup with seven different prophylaxis and polishing pastes. All the samples were then prepared for scanning electron microscopy (SEM) evaluation and photographed at 750x to compare the effects of polishing on the surfaces of composite resins. SEM photographs were also made of a sample polished with Soflex discs (SF) and with a dry rubber cup (RC). The seven prophylaxis and polishing pastes were Command Ultrafine Lustre Paste (CULP), Coral Phosphate Prophylaxis Paste (CPPP), NuPro fine (NPF), NuPro medium (NPM), Prophydent (PD), Rembrandt Polishing Paste (RPLP) and Rembrandt Prophylaxis Paste (RPXP). The SEM photographs were rated by independent evaluators according to surface roughness from the smoothest to roughest surfaces. The results of the evaluator ratings determined that the composite resin surface gets rougher with the use of any polishing paste. The smoothest to roughest surface by groupings were: (SF)-(RPLP)-(CULP, RC)-(RPXP)-(NPF, CPPP, PD)-(NPM).
临床上，复合树脂在填充时可使用多种抛光方法将其表面抛光至光滑。后续复诊时维持这种光洁度需要进行评估。本研究的目的是比较用预防性抛光膏和抛光膏对一种小颗粒复合树脂（平均粒径5微米）进行抛光后的表面纹理。小颗粒复合树脂PrismaFil的每个样本先用Soflex盘片进行修整和抛光，使其表面光滑，这是对照抛光。然后用装有七种不同预防性抛光膏和抛光膏的旋转橡胶预防性抛光杯对样本进行抛光。然后所有样本都准备用于扫描电子显微镜（SEM）评估，并在750倍放大倍数下拍照，以比较抛光对复合树脂表面的影响。还对用Soflex盘片（SF）和干橡胶杯（RC）抛光的样本制作了SEM照片。七种预防性抛光膏和抛光膏分别是Command超精细光泽膏（CULP）、珊瑚磷酸盐预防性抛光膏（CPPP）、NuPro细粒度（NPF）、NuPro中粒度（NPM）、Prophydent（PD）、伦勃朗抛光膏（RPLP）和伦勃朗预防性抛光膏（RPXP）。独立评估人员根据表面粗糙度从最光滑到最粗糙对SEM照片进行评级。评估人员评级结果表明，使用任何抛光膏都会使复合树脂表面变得更粗糙。按组别从最光滑到最粗糙的表面依次为：（SF）-（RPLP）-（CULP、RC）-（RPXP）-（NPF、CPPP、PD）-（NPM）。
