Title

Color Stability of Ceramic Veneers Cemented with Self-Adhesive Cements after Accelerated Aging

Pages

  393-401

Abstract

 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 (Δ E=4. 2) after aging, and its color change was clinically unacceptable (Δ E>3. 5). The color change of the other two groups was clinically acceptable (1<Δ 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.
