Proper selection of cement plays an effective role in the success of ceramic laminate veneers. The cement can affect the final color by changing the optical properties of the ceramic.
Due to the ease of clinical use of the seventh generation of cement (Self-Adhesive Cement), this study aimed to evaluate the effect of this type of cement on the final color of Ceramic Veneers (CV).
In this study, 21 IPS e.max ceramic disks (8mm× 0.7 mm) were used. They were divided into 3 groups of 7, depending on the type of cement. (Choice 2, RelyX U200, Speed Cem). In the first stage, ceramic disks were set on the facial surface of bovine’s teeth by bonding agents and the color properties were analyzed by spectrophotometer. In the next stage, specimens were cemented on the prepared surfaces according to the manufacturer’s instructions and their color was evaluated subsequently.
Results were analyzed by repeated measures two-way ANOVA and TAMHANE post hoc methods (P < 0.05). Results showed that cement influences the color of the ceramic laminate. ∆E values were reported to be higher than the critical point after cementation (∆E > 2.69).
There was no significant difference between the effects of three cement types on the final color of the ceramic veneers.
