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 (ΔE 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 
value after bonding with the resin cement. The ΔE values of ceramic disks after cementation ranged from 1.38 to 7.16. The ΔE
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 ΔE values revealed significant differences in the resin cement shades.

Resin
cements can affect the final color of ceramic veneer restorations, and
the extent of this effect varies according to the resin cement shades.
