Aim: To compare the color stability of Ceramage and Ceramage DUO indirect composite restorative materials (Shofu Inc., Kyoto, Japan) using a thermocycling stain challenge model to simulate the complex effects of staining foods and beverages in the oral environment.

Materials and Methods: 10 disc each from shade A1 subtypes (Dentin Body A1B, Incisal 58, and Translucent HVT) of Ceramage and 10 disc each from shade A1 subtypes of (Dentin Body A1B, Incisal 58, and Translucent HVT) of Ceramage DUO were subjected to thermocycling stain challenge in soy sauce and lemon iced tea at 500 cycles followed by 10 minutes of ultrasonic cleaning. L*, a* and b* color coordinates were measured spectrophotometrically and the mean color difference (ΔE) at different stages of experiment were measured and compared using repeated measure ANOVA (within-between group).

Results: Ceramage showed greater stain retention compared to Ceramage DUO. There was a significant difference in color changes at all experimental stages (F=65.747b, p<0.0001) and the mean color difference (ΔE) for Ceramage does not overlap with the corresponding confidence interval of the Ceramage DUO.

Conclusion: Ceramage DUO showed significantly greater color stability compared to Ceramage indirect composite.
