Abstract :Objective: The objective of this study was to investigate the effects of liquid coloring in different dipping times and finishing procedures on color difference of precolored and liquid-colored monolithic zirconia ceramics. Materials and Methods: 240 zirconia specimens were divided according to shades of coloring liquid insert ignore into journalissuearticles values(A1, A2, and A3);, dipping time insert ignore into journalissuearticles values(3, 5, and 7 minutes);, and surface finishing procedures insert ignore into journalissuearticles values(glaze and mechanical polishing); insert ignore into journalissuearticles values(n=10);. CIE L*, a*, and b* values of the specimens were measured and color differences insert ignore into journalissuearticles values(ΔE); were calculated. The data were analyzed with three-way analysis of variance insert ignore into journalissuearticles values(ANOVA); and Tukey HSD test insert ignore into journalissuearticles values(α=.05);. Results: Coloring with liquids, dipping time, and finishing procedures significantly affected the CIE L*, a*, and b* values insert ignore into journalissuearticles values(P<.001);. Dipping in coloring liquids decreased the a* and b* values. Higher L* values were obtained in glazing groups than mechanical polishing groups. The ΔE values among the experimental groups were varied from 7.10 to 27.52. The highest color difference was observed in 7 min dipping in A3 liquid and mechanically polished group. Conclusion: The color difference between the precolored and liquid-colored zirconia ceramics are not in acceptable limits. Dipping in coloring liquids and surface finishing affect the color of liquid-colored monolithic zirconia.
