The purpose of this in vitro study was to evaluate the surface finish and gloss of five direct resin composites polished with six polishing systems.
One hundred and fifty disk-shaped composite specimens (D=10.0 mm, 2-mm-thick, N=30 per material) were made. One side of each specimen was finished with a 16-fluted carbide finishing bur and then polished. Five specimens of each resin composite were randomly assigned to one of the six polishing systems. The surface roughness and gloss were measured with a surface profilometer and a glossmeter. The results were analyzed by two-way analysis of variance and Tukey's t-test (p<or= 0.05).
There was no significant interaction between the composite and the polishing systems for surface roughness (p=0.059). The order of surface roughness ranked according to composite was: Durafill < Esthet-X < Supreme < Z250 < Z100; and the ranking for the polishing system was: Pogo < Sof-Lex < Diacomp/Enamelize < Diacomp < ComposiPro brush < Jiffy. There was interaction of gloss values between the composites and the polishing systems (p < 0.001). The highest gloss value was recorded for Supreme + Pogo; the lowest was recorded for Z100 + Jiffy. Pogo showed the highest gloss values for all composites.
The nanofill (Supreme) and minifill (Esthet-X) composites presented a surface roughness comparable to a microfill (Durafill), independent of the polishing system used, and a gloss comparable to a microfill, when polished with a one-step system (Pogo). As compared with the multiple-step systems, the smoothest surfaces and the highest gloss values were achieved using the one-step system (Pogo) for all the evaluated composites.
本体外研究的目的是评估用六种抛光系统对五种直接树脂复合材料进行抛光后的表面光洁度和光泽度。
制作了150个圆盘状复合树脂标本（直径 = 10.0毫米，厚度2毫米，每种材料30个）。每个标本的一侧先用16刃硬质合金修整车针进行修整，然后进行抛光。每种树脂复合材料的五个标本被随机分配到六种抛光系统中的一种。使用表面轮廓仪和光泽仪测量表面粗糙度和光泽度。结果通过双向方差分析和Tukey t检验进行分析（p≤0.05）。
复合材料和抛光系统之间在表面粗糙度方面没有显著的交互作用（p = 0.059）。按照复合材料排列的表面粗糙度顺序为：Durafill < Esthet-X < Supreme < Z250 < Z100；按照抛光系统排列的顺序为：Pogo < Sof-Lex < Diacomp/Enamelize < Diacomp < ComposiPro brush < Jiffy。复合材料和抛光系统之间在光泽度值上存在交互作用（p < 0.001）。Supreme + Pogo记录到最高光泽度值；Z100 + Jiffy记录到最低光泽度值。Pogo对所有复合材料都显示出最高的光泽度值。
纳米填料（Supreme）和微填料（Esthet-X）复合材料呈现出与微填料（Durafill）相当的表面粗糙度，与所使用的抛光系统无关，并且在用一步法系统（Pogo）抛光时，其光泽度与微填料相当。与多步法系统相比，对所有评估的复合材料使用一步法系统（Pogo）可获得最光滑的表面和最高的光泽度值。
