This study evaluated the results of polishing composite resin by using the following finishing and polishing techniques: Arkansas stone burs; eight-blade tungsten-carbide burs; diamond burs; aluminum-oxide disks; no polishing; and 12- and 30-blade tungsten-carbide burs. The results were compared to ascertain which technique delivers the smoothest surface. The study was done with 120 class V restorations on extracted human teeth distributed in two groups (I and II) of 60 restorations each. Group I teeth samples were filled with microfilled composite resin and Group II with a hybrid composite resin. Readings were made with a profilometer to evaluate the final polishing. The conclusions from the results of the study were that microfilled composite resins provided a better finish when treated with aluminum-oxide disks. These results were statistically significant (p < 0.001). When hybrid composites were used the control group recorded the lowest values.
阿肯色石车针;八刃碳化钨车针;金刚石车针;氧化铝盘;不抛光;以及十二刃和三十刃碳化钨车针。对结果进行比较以确定哪种技术能产生最光滑的表面。该研究对120颗拔除的人牙上的V类洞修复体进行,分为两组(I组和II组),每组60个修复体。I组牙齿样本用微填料复合树脂填充,II组用混合复合树脂填充。使用轮廓仪进行读数以评估最终抛光效果。研究结果得出的结论是,微填料复合树脂用氧化铝盘处理时能获得更好的修整效果。这些结果具有统计学意义(p < 0.001)。当使用混合复合树脂时,对照组记录的值最低。
