Özet
This study was performed to evaluate wear, surface hardness and roughness characteristics of light cured restorative composites, porcelain and enamel when opposed by human enamel. Five composite resins (3MSilux, ClearfilAP-X, 3MFiltek Z250, Pekalite, SureFil), one ceramic (VitadurAlpha) and enamel were selected as experimental materials. The antagonist abrasives were made by using buccal enamel of anterior teeth. Ten rectangular specimens were prepared for each material. The at the beginning of the study, the mean weight, roughness and hardness values of specimens were obtained. Then the specimens were opposed by human enamel and subjected to 20.000 sliding cycles in a prototype wear machine. Surface characteristics and final weights of each materials were recorded and compared to the values obtained at the beginning. Statistically significant differences were found among the hardness and roughness of materials (p<0.05). After wear procedure, surface hardness of all materials increased. There was not any significant difference among the wear values of materials and enamel.
