Abstract: Purpose: Dental composite resins are commonly used restorative materials for the replacement of hard dental tissues.The aim of this study was to evaluate the effect of a surface sealant on the surface roughness of different composites and compare their microhardness values. Materials and Methods:Sixty disc-shaped test specimens were prepared and assigned to 3 experimental and 3 groups (n =10 per group).Discs in the group 1 were prepared using Herculite XRV Ultra (Kerr Corporation, Orange, CA, USA); group 2, using Beautifil Bulk Restorative (SHOFU INC., Kyoto, Japan); and group 3, using Filtek Bulk Fill Posterior Restorative (3M-ESPE Dental, Germany).Discs in experimental groups 4, 5, and 6 were prepared using surface sealant (BisCover LV) in addition to the restorative materials used in groups 1, 2, and 3, respectively.The group 1, 2, and 3 discs surface hardness and group 1, 2, 3, 4, 5, 6 surface roughness were measured using the Vickers hardness test and a profilometer, respectively.One-way ANOVA was used to test for differences among the groups.Results: No significant differences were observed in the microhardness and roughness between the experimental and control groups for each restorative materials.Based on the numerical values Group 3 showed the highest surface hardness and group 4 showed the lowest surface roughness values, respectively.Conclusion: Using the BisCover LV resin after the polishing step has no significant effect on the surface.The highest hardness values were obtained for the Filtek Bulk Fill Posterior Restorative after the polishing step.Smoothest surfaces were obtained for all experimental groups using the BisCover LV resin after the polishing step, Herculite XRV Ultra showed lower average roughness values than the other materials.
