Evaluation of the esthetic effect of resin cements and try-in pastes on ceromer veneers

Abstract

Objective To evaluate the influence of various shades of resin cements on the final color of ceromer veneers and analyse the agreement of resin cements and corresponding try-in pastes. Methods Ceromer disks (Ceramage, 1.0 mm × 10 mm diameter) were bonded to resin background disks (3.0 mm × 10 mm diameter) using five shades of resin cements (RelyX Veneer), whilst butylphthalate was placed between ceromer and resin background as the control group ( n = 5). The corresponding try-in pastes were placed between ceromer and resin background disks using the specimens of the control group. After colorimetric evaluations, the thickness of ceromer disks was reduced to 0.8 and 0.5 mm. Color measurements were repeated at each thickness. To analyse masking ability of the cement, resin background disks with 0.1 mm thick cement layer were fabricated using five shades of resin cements ( n = 5). Result Two-way ANOVA of Δ E values of cement shades and control group revealed significant differences in cement shade and thickness, and their interaction ( p < 0.001). The 0.5 mm thick Ceramage specimens yielded the highest mean Δ E values (2.44 ± 1.12) for all cement shade groups. A3, WO, and B05 shade of resin cements created perceptible color differences (Δ E > 2.0) in 0.5 mm thick specimens and WO shade in 0.8 mm thick specimens. There were no perceptible color differences between resin cements and corresponding try-in pastes. Conclusion The effect of resin cements on the final color of ceromer veneers depended on cement shades and thickness of ceromer. The color of resin cements and corresponding try-in pastes achieved high agreement.
