This study compared surface roughness and gloss produced by different finishing/polishing procedures for two resin composites, Clearfil AP-X (AP-X) and Estelite Sigma (ES). A total of 70 composite discs (n=35 for each resin composite) were prepared and divided at random into seven finishing/polishing groups (n=5): glass-pressed control; using a super-fine-grit diamond bur (SF); using CompoMaster (CM) after SF-finishing (SF+CM); using White Point (WP) after SF-finishing (SF+WP); using CM after SF+WP-finishing (SF+WP+CM); using Stainbuster (SB) after SF-finishing (SF+SB); and using CM after SF+SB-finishing (SF+SB+CM). After the finishing/polishing procedures, average surface roughness (R(a)) and surface gloss (Gs(60( degrees ))) of all specimens were assessed with a surface profilometer and specimen gloss meter, respectively. Glass-pressed controls for both AP-X and ES composites showed the best surface finish in terms of both R(a) and Gs(60( degrees )). SF-finishing produced the roughest surface and led to almost complete loss of gloss. While additional polishing with CM reduced R(a) and increased Gs(60( degrees )), the additional finishing effect of WP or SB between SF-finishing and CM-polishing was not found for either AP-X or ES.
本研究比较了两种树脂复合材料Clearfil AP-X（AP-X）和Estelite Sigma（ES）采用不同修整/抛光程序后的表面粗糙度和光泽度。共制备了70个复合树脂圆盘（每种树脂复合材料35个），并随机分为7个修整/抛光组（每组5个）：玻璃压铸对照；使用超细粒度金刚石车针（SF）；在SF修整后使用CompoMaster（CM）（SF+CM）；在SF修整后使用White Point（WP）（SF+WP）；在SF+WP修整后使用CM（SF+WP+CM）；在SF修整后使用Stainbuster（SB）（SF+SB）；以及在SF+SB修整后使用CM（SF+SB+CM）。在完成修整/抛光程序后，分别使用表面轮廓仪和样品光泽仪评估所有试样的平均表面粗糙度（R(a)）和表面光泽度（Gs(60(度))）。就R(a)和Gs(60(度))而言，AP-X和ES复合材料的玻璃压铸对照均显示出最佳的表面光洁度。SF修整产生了最粗糙的表面，并导致光泽几乎完全丧失。虽然用CM进行额外抛光降低了R(a)并提高了Gs(60(度))，但对于AP-X或ES，在SF修整和CM抛光之间未发现WP或SB的额外修整效果。
