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
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.
light-cured resin cements showed greater color stability. The lighter shades of luting were more
likely to display a greater color change.
