Comparison of Polishing Systems on the Surface Roughness of Resin Based Composites Containing Different Monomers

Changes in the organic matrix of composite resins have been proposed to improve their surface properties. However, polishing systems may perform differently different materials. This study compared effect on roughness four containing resin monomers: Admira Fusion (nanohybrid pure ormocer), Aura Bulkfill Bis-GMA, UDMA), Charisma Diamond TCD-DI-HEA) and Vittra APS (nanofilled UDMA). Cylinders (N = 120, n 10) were prepared from each material top specimen was grounded using a diamond finishing bur. Baseline measurements (Ra) recorded contact profilometer specimens divided into three subgroups according system: one-step, two-step, three-step. Ra also after polishing. Data analyzed three-way ANOVA Tukey’s test (p < 0.05). The baseline all composites significantly reduced 0.001). two-step system provided smoothest for (0.0770 ± 0.0171) (0.1091 0.0090), whereas no differences found tested. smoothness seems be more dependent than step dependent, but tested clinically acceptable results.
