Abstract
BACKGROUND: To determine the effectiveness of three polishing systems on three different composite materials by evaluating surface roughness using a Profilometer and Scanning electron microscope. METHODOLOGY: A total of Sixty-three resin composite disks were prepared in rectangular acrylic mould of 8×2mm dimension, with 4mm thickness. Specimens were made of light activated resin composite Filtek Z-250-XT, Tetric-N-Ceram bulkfill, Ceram X Duo. The sixty-three samples were divided into three groups of twenty-one samples each i.e. Group A (Filtek Z-250-XT), Group B (TetricN-Ceram bulkfill) and Group C (Ceram-X-Duo).Out of 21 samples of each of the material, 7 specimens were polished with multi enhance polishing agents, 7 specimens were polished with super snap polishing agents and 7 specimens were polished with sof-lexdiscs.Surface roughness of each sample after polishingwasevaluatedusingProfilometer and Scanning electron microscope. RESULTS: One-way anova and kruskalwallis test was used for statistical analysis. Ceram-X-Duo gave least roughness average value with Super snap polishing system when compared to multi enhance and sof-lex polishing system. CONCLUSION: Super snap polishing system is a better polishing system than multi enhance and soflex and Ceram-X-Duo composite material offers better polishability compared to Filtek Z-250-XT and Tetric-N-Ceram bulk fill.
