摘要
目的:测定含球形填料的不同树脂基复合材料在采用不同体系和不同应用步骤(一步、两步或三步)进行光整抛光后表面粗糙度的变化。材料与方法:采用三种不同的RBC材料(n=40个/组)制备120个圆盘状标本(直径10 mm ×厚度2 mm):纳米填充树脂复合材料(Omnichroma);纳米陶瓷树脂复合材料(Neo Spectra ST)和纳米混合树脂复合材料(Charisma Topaz)。每组按精加工/抛光(F/P)系统分为4个子组(n=10):控制(无F/P),一步系统(增强);两步制(Super Snap Rainbow);三步制(Soflex)。用轮廓仪测量平均Ra。为了比较无F/P和F/P后RBC材料的表面粗糙度,收集的数据使用双向方差分析(ANOVA),学生t检验和单向方差分析与Tukey事后检验进行统计分析。显著性水平为p<0.05。结果:纳米填充树脂复合材料的Ra平均值最低,纳米陶瓷树脂复合材料的Ra平均值最高。三种红细胞材料的Ra、F/P和F/P后的差异有统计学意义(P <0.001)。结论:不同的抛光系统对红细胞的表面粗糙度有明显的影响。纳米填充树脂复合材料的表面粗糙度最低。两步F/P系统提供了最佳的树脂基复合材料F/P方案。
Effect of Finishing/Polishing Techniques on Surface Roughness of Three Different Resin Composite Materials: A laboratory Study
: Objective: To determine the changes in surface roughness of different resin based composite materials having spherical shaped fillers after finishing and polishing with different systems and various application steps either one, two or three-steps. Materials and Methods: A total of 120 disc-shaped specimens (10 mm diameter × 2 mm thickness) were prepared from three different RBC materials (n=40 discs/group): a Nano-fill resin composite (Omnichroma); a Nanoceramic resin composite (Neo Spectra ST) and a Nano-hybrid resin composite (Charisma Topaz). Each group was subdivided into four subgroups (n=10) according to the finishing/polishing (F/P) system: control (without F/P), one-step system (Enhance); two-step system (Super Snap Rainbow); and three-step system (Soflex). The mean Ra was measured using the profilometer. To compare the surface roughness between RBC materials without and after F/P, the collected data were subjected to statistical analysis using two-way analysis of variance (ANOVA), Student’s t-test and One-way ANOVA with Tukey’s post hoc tests. The level of significance was seated p<0.05. Results: The Nano-fill resin composite showed the lowest mean Ra while the Nano-ceramic resin composite showed the highest value. A statistically significant difference was found in Ra and without and after F/P for the three RBC materials (p<0.001). Conclusions: The various finishing and polishing systems had a noticeable effect on the surface roughness of the RBCs. The Nano-fill resin composite had the lowest surface roughness. The two-step F/P system provided the best F/P protocol of resin based composites evaluated.
