Color Matching between Resin Cements and Try-in Pastes in Glass Ceramics at Different Thicknesses

Aim: This study aims to assess how well light-cured resin cements and the corresponding try-in pastes match in terms of color. Materials and Methods: A1 color blocks containing three different types of ceramic materials were used to generate 120 specimens (5 x 5 mm2). These specimens were split into two thickness-based groups, and the groups were then randomly allocated to receive various kinds of resin cement. Composite substrate blocks with A3 color and dimensions of 4 mm thickness were used to simulate dentin substrates. Color measurements were taken before and after the application of try-in pastes and resin cements using a spectrophotometer. The obtained results were analyzed using the CIELab and CIEDE2000 frameworks, and statistical analysis was performed using a three-way ANOVA test and paired sample t-test with a significance level of alpha = 0.05. Results: There were no significant interactions between material, thickness, and cement in relation to color in both evaluation systems (p > .05). However, there were significant differences in the a* values (green-red axis) between the try-in pastes and resin cements (p < .05), while no significant differences were observed in the L* (lightness) and b* (blue-yellow axis) values (p > .05). Conclusion: The try-in pastes utilized for pre-cementation evaluation exhibited favorable color compatibility with the corresponding resin cements.
