dc.description.abstractAim: The purpose of this study was to compare the influence of different polishing systems on the surface roughness of nano-hybrid composite resins. Materials and Methods: Fourty samples of acrylic blocks were prepared with cold cure acrylic resin in plastic rings of 1 inch diameter. In each acrylic block, a well of 6mm diameter and 2mm depth was prepared by drilling hole in it using a slow speed micromotor. Tetric N-Ceram™ nano composite is placed in the wells prepared using a plastic instrument and covered with a mylar strip. The samples were then cured for 40s through the mylar strips using LED curing light. 60 samples were divided into 4 groups with 15 samples in each group based on polishing regimen used. Group A - Mylar strip, Group B- PoGo diamond polishers, Group C- prophy brushes and Group D- Super- Snap Rainbow kit. The polished resin composite discs were washed, allowed to dry and kept again in 100% humidity for 24 h before measuring the average surface roughness values (Ra). The surface roughness test was performed using a profilometer and surfaces are seen under scanning electron microscope[SEM]. Statistical analysis: The data were analysed by using one-way ANOVA using SPSS 17.0 software. Results: For all the materials, the smoothest surface was obtained with mylar strip and the roughest with prophy brushes(P< 0.05).Conclusion: Mylar strip produced smoothest surface than other polishing systems.en_US
