Abstract

Purpose: To evaluate the effect of three brands of resin cement on the final color of ceramic veneers. Methods: 50 disk-shaped ceramic specimens (IPS e.Max, 0.6. mm × 8.0. mm diameter) and disk-shaped composite resin background specimens (4.0 mm. × 8.0. mm diameter) were prepared and divided into 10 groups (n= 5). These paired specimens were bonded using ten shades of resin cement (Variolink Veneer, shades LV-3, LV-2, MV, HV + 2, HV + 3; Panavia F, shades light and brown; and RelyX™ Veneer, shades WO, TR, A3). A spectrophotometer (VITA Easyshade) was used to measure the color parameters (CIE L* a* b* values) of the paired disks before and after cementation. The color differences (δ E values) after cementation were calculated and statistically analyzed by the One-way ANOVA (at the significant level p< 0.05). Results: The color parameters of the ceramic disks were measured in terms of the increase in L* value, and the decrease in Cab* value after bonding with the resin cement. The δ E values of ceramic disks after cementation ranged from 1.38 to 7.16. The δ E values were more than 3.3 when the ceramic disks were cemented with resin cements in shade HV + 3 (4.90) and shade WO (7.16). One-way ANOVA of δ E values revealed significant differences in the resin cement shades. Conclusions: Resin cements can affect the final color of ceramic veneer restorations, and the extent of this effect varies according to the resin cement shades.
