Purpose: 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 specimens were prepared and assigned to 6 groups (n =10). Groups were prepared as follows; Group 1 (Herculite XRV Ultra), Group 2 (Beautifil Bulk Restorative) and Group 3 (Filtek Bulk Fill Posterior Restorative).
