Abstract
This study aims to evaluate the Knoop microhardness on the surface and at different depths of three conventional composites and three high viscosity bulk-fill composites. 48 samples (n = 10) in cylinder form will be made. The samples will be divided into 6 experimental groups according to the composite (conventional Tetric N-Ceram, Tetric N-Ceram Bulk-fill - IVOCLAR VIVADENT, Filtek Z350 …
