Aim: To determine the surface roughness of esthetic restorative materials after finishing and polishing. Materials and Methods: All 60 specimens were divided into four groups. Group I: Nanocomposite, Z 350 XT (3M ESPE, USA); Group II: Microhybrid composite, Z 250 (3M ESPE, USA); Group III: Compomer, Dyract XP (LD Caulk/Dentsply, USA); and Group IV: Resin modified glass ionomer cement (GIC), Fuji II LC (GC, Japan). Each group was again divided into three subgroups. Subgroup A: Sof-Lex (3M ESPE); Subgroup B: Super-Snap Rainbow finishing and polishing kit (Shofu INC, Japan); and Subgroup C: Control Mylar strip. Surface roughness was determined by Perthen Perthometer S6P profilometer. Result: Filtek Z350 XT showed minimum surface roughness followed by Filtek Z250, Dyract XT and Fuji II LC. Super-Snap exhibited less surface roughness than Sof-Lex polishing systems. Statistical Analysis: One-way analysis of variance (ANOVA) followed by multiple post hoc comparisons using least square difference method and unpaired t-test was used. Conclusion: Filtek Z350 XT with Mylar strip exhibited least surface roughness.
