Aim: To evaluate the color stability of dual cure and light cure resin cements immersed in coffee solution at different time periods (baseline, 3 days and 1 week). Materials and methods: The color stability of three light curing (Variolink Esthetic (VLC); Rely X Veneer (RLC) and Mojo Veneer (MLC)) and three dual curing (Variolink Esthetic (VDC); Rely X Ultimate (RDC) and Breeze (MDC)) resin cements were tested. A total of sixty disks (10 mm diameter and 0.5 mm thickness) were prepared using a silicone mold (n=10). The specimens were subjected to baseline color measurement using Commission Internationale de l’Eclairege L*a*b* (CIELAB) color space system with the help of a spectrophotometer (LabScan XE, HunterLab, VA, USA). Following baseline color measurements, the specimens were immersed... in a staining coffee solution. The color measurement was repeated after 3 days and 1 week of immersion in coffee solution. All the data collected were statistically analyzed using repeated measures of Analysis of variance (ANOVA, P<0.05). Result: After one week of storage in coffee solution, the mean color measurement scores in light cure group were found to be higher for RLC (1.22 ± 1.51) followed by VLC (0.85 ± 0.65) and NLC (0.68 ± 0.36) whereas in dual cure group, the mean color measurement scores were found to be higher for NDC (7.45 ± 4.50) followed by RDC (1.52 ± 1.24) and VDC (0.47 ± 0.34). Repeated measures ANOVA showed a statistically significant difference for light cure group (P=.004) at different time intervals but no significant difference with respect to dual cure group (P=.26). Conclusion: There was a significant difference observed between the light- and dual-cured cements over a different period of time. The color changes of both light- and dual-cure resin cements were within clinically acceptable limits except for the dual-cured Breeze cement.
