Abstract

Background and Aims: To evaluate the effect of POLISHING on surface roughness of silorane-based COMPOSITE using profilometery and SEM and compare it with that of a methylmethacrylate-based COMPOSITE and a GLASS IONOMER.Materials and Methods: In this study, 3 groups (n=28) were tested: specimens of two COMPOSITEs (Filtek P90 and Filtek P60) and a GLASS IONOMER (Fuji IX) which were prepared in polyethylene molds (4 mm diameter × 10 mm height). Half of the specimens in each group were finished with 180-grit silicon carbide paper and the remaining samples were finished with 180-grit, and subsequently polished with 250, 400, 800, 1000, 2000, and 2500-grit silicon carbide papers. The surface roughness was evaluated using a contact profilometer and then mean (Ra) and maximum (Rmax) of surface roughness and were recorded. Then, the surface of 4 specimens of each subgroup was observed under the field emission scanning electron microscopy. Statistical analysis was performed with T-test, ANOVA and Dunnett T3 tests.Results: In all materials, Ra was different between POLISHING with 180 and 2500-grit silicon carbide papers. In 180-grit group, only Ra of Filtek P60 and Fuji IX showed significant difference (P=0.01). In 2500-grit group, there was no significant difference between the Ra of Filtek P60 and Filtek P90 (P=0.56).Conclusion: POLISHING is recommended for Fuji IX and posterior COMPOSITE restorations.
