摘要/Abstract

摘要： 目的:研究不同抛光方法对树脂表面粗糙度的影响。方法:6种树脂Filtek Z350、Filtek P60、Ceram-X mono、Quixfil、Synergy Duo Shade、Synergy compact分别制成共120个树脂块(5 mm×4 mm),分别使用Sof-Lex抛光碟(S)、PoGo抛光杯(PG)、Brilliant Golss抛光杯(BG)抛光。原子力显微镜测表面粗糙度参数RMS,并行统计学分析。结果:干法抛光时,S+Synergy Duo Shade的RMS值最小;PG+Quixfil值最大。对同一树脂使用不同抛光方法, RMS差异无显著性(P>0.05),组间两两比较示Ceram-X的抛光效果S优于PG(P<0.05)。相同方法抛光不同树脂,纳米型与混合型树脂抛光效果优于可压型复合树脂。PG抛光Quxifil和Ceram-X,BG抛光Synergy Duo Shade时干法优于湿法(P<0.05)。结论:对同一树脂使用不同的抛光方法,其表面粗糙度无显著差异。相同抛光方法,可压型复合树脂的RMS高于其他。部分树脂干法抛光效果优于湿法。

Abstract: Objective: To examine the surface roughness of composite resins treated by different polishing systems. Methods: A total of 120 composites resin samples (5 mm×4 mm) were prepared including Filtek Z350, Filtek P60, Ceram-X mono, Quixfil, Synergy Duo Shade, and Synergy compact. They were polished with Sof-Lex discs (S), PoGo cups (PG), and Brilliant Golss cups (BG). The surface roughness parameters (RMS) of composite samples were measured by atomic force microscopy (AFM) and analyzed statistically. Results: For dry polishing, S + Synergy Duo Shade showed the lowest RMS value; PG + Quixfil showed the highest value. There was no significant difference in RMS for the same resin using different polishing methods, and a two-way comparison between groups showed that the polishing effect of CeramX was better for S than for PG (P<0.05). Nanofill and hybrid resin showed smoother surfaces compared to the packable resin after the same polishing methods. The dry polishing method showed a better effect when PG polishing Quxifil/CeramX and BG polishing Synergy Duo Shade (P<0.05).Conclusion: There is no significant difference in surface roughness when different polishing methods are used for the same resin. The RMS of packable composite resin is higher than others for the same polishing method. Some resins show better effects in dry polishing method.
