This study aimed to assess the color stability of ceramic laminate veneers cemented with self-adhesive resin cements after accelerated aging. Materials and Methods: In this study, 21 IPS e.max ceramic discs, measuring 8mm in diameter and 0.7 mm in thickness, were fabricated and divided into three groups (n=7) for the application of Choice 2 total-etch light-cure resin cement, RelyX U200 dual-cure self-adhesive resin cement, and SpeedCEM self-cure self-adhesive resin cement. The ceramic discs in each group were cemented on the prepared facial surface of bovine teeth. The color parameters were assessed using a spectrophotometer. Subsequently, the samples were subjected to accelerated aging for 100 hours, and the color parameters were measured again. The data were analyzed using two-way repeated-measures analysis of variance (ANOVA) and Tamhane’s post-hoc test (P<0.05). Results: Aging significantly affected the ceramic laminate color parameters in all three groups (P<0.05). SpeedCEM cement showed the lowest color stability (∆E=4.2) after aging, and its color change was clinically unacceptable (∆E>3.5). The color change of the other two groups was clinically acceptable (1<∆E<3.5). Conclusion: The self-adhesive dual-cure cement showed color stability comparable to that of the total-etch light-cure cement for cementation of IPS e.max ceramic laminates. The color stability of both cements was superior to that of the self-adhesive self-cure cement. https://fid.tums.ac.ir/index.php/fid/article/view/3087 https://fid.tums.ac.ir/index.php/fid/article/download/3087/1779
