Color Stability of Ceramic Veneers Cemented With Self-Adhesive Cements After Accelerated Aging

Objectives: color change of cements over time can be detected through translucent ceramic veneers, compromising the aesthetic appearance of restorations in the long-term. 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 (δe=4.2) after aging, and its color change was clinically unacceptable (δe>3.5). the color change of the other two groups was clinically acceptable (1<δe<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.
