Abstract:

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. Data analysis was performed using Student t-test and Aasistat 7.6 statistics software in experimental composite groups, It was found that group B composite recorded statistically significant higher (p=0.009 < 0.05; Weight loss mean value than group A composite mean value). Also group B composite recorded higher, statistically non-significant (p=0.09 >), roughness change mean value than group A composite mean value. In antagonistic cusp groups, it was found that group B antagonistic cusp recorded, statistically non-significant, higher weight loss mean value than group A antagonistic cusp mean value. Also group A antagonistic cusp recorded, statistically non-significant, higher roughness change mean value than group B antagonistic cusp mean. Nanoparticles zirconia resin composite showed high wear resistance and bioactive composite showed a clinically accepted wear resistance.
