ABSTRACT
The color stability of resin cements is essential for aesthetic restorations. Aim:
To evaluate the influence of shade and aging time on the color stability of two light-cured and two dual-cured resin cements.Methods:
The CIE-Lab color parameters (n=6) were measured immediately after sample preparation and at 7, 30 and 90 days of aging in distilled water. The color difference (ΔE) was calculated and then analyzed by three-way ANOVA for repeated measures and Tukey's HSD test (α=0.05).Results:
ΔE was higher for transparent resin colors, followed by dark and light colors. The mean values of ΔE were lower for both light-cured resin cements compared to the dual-cured cements. As the aging time increased, ΔE values increased.Conclusions:
The light-cured resin cements showed greater color stability. The lighter shades of luting were more likely to display a greater color change...
