AIM: The aim of this study is to evaluate the effect of four different surface finishing methods and aging on the surface roughness and color stability of dental hybrid ceramic. MATERIAL AND METHODS: Hybrid ceramic blocks were prepared with dimension of 12x14x1 mm and 4 groups were determined as; polishing with technical kit (ET), polishing with clinical kit (EC), glazing of sandblasting surface (ES) and glazing of etching surface (EA) (n=10). Color parameters and surface roughness values were measured. Thermocycling procedure was applied. Color and surface roughness values were re-measured. ΔE values were calculated and data was analyzed with Kruskal Wallis, Bonferroni Dunn and Wilcoxon signed ranks tests. Surface analysis were performed with scanning electron microscope to 2 specimens of each group. RESULTS: Significant difference was not observed among ΔE values of the groups with different types of surface finishing procedure. Before and after aging, EA group had lowest surface roughness values. After aging, surface roughness values increased for ES group. CONCLUSION: The color stability of hybrid ceramic material was not affected by the surface finishing method, and the lowest surface roughness values were observed in the glazing of sandblasting surface group.
