The aim of this study was to evaluate the wear resistance of recent commercially available dental composites. Tested composite samples were divided into two groups. Each group involved 20 prepared composite discs. For antagonist, enamel samples, 20 premolar buccal cusps were selected, prepared and embedded in acrylic mold. The two body wear testing was performed using a programmable logic controlled equipment. Surface roughness evaluated using digital microscope and images analysis. |
