Abstract
Objective:To compare the effects of different polishing and glazing methods on the roughness and gloss of ceramic surface.Methods:Sixty ceramic samples(VITA VMK95) were divided into 6 groups according to different polishing and glazing methods.Roughness and gloss of each ceramic sample was measured after different polishing process.The data were analyzed by ANOVA analysis.Results:The surface roughness of ceramics glazed after green stone polishing was significantly higher than that of the other groups(P0.05).After being polished with green stone,the ceramics treated by normal glazing process were smoother than self-glazed ones(P0.05).The surface roughness of glazed ceramics which were polished by green stone combined with Softcut Polishers(Group A2,B2) were comparable with the directly glazed(Group A,B)ones(P0.05).The glosses of all the tested groups were comparable(P0.05).Conclusion:Different polishing and glazing methods have significant effects on the surface roughness of ceramics,while the surface gloss of ceramics is not affected.
