Abstract

Objective The purpose of this in vitro study was to evaluate color stability of resin cements which have different compositions and shades after immersed in different solutions and various times. Materials and methods Six resin cements of 2 shades (clear and white opaque) of each product, 4 conventional: Nexus 3 light-cured (NxL); Nexus 3 dual-cured (NxD); RelyX Veneer light-cured (RvL); Variolink Veneer light-cured (VvL) and 2 self-etch-self-adhesive : Maxcem Elite dual-cured (MxD) and RelyX Unicem Aplicap dual-cured (RuD), were used. Twenty round disk specimens (12 mm in diameter, 0.8 mm in height) in each group were prepared. The initial color of each specimens was assessed as baseline color using spectrophotometer (Ultrascan XE, Hunter Lab, USA). Then specimens of each group were divided into 2 subgroups and were immersed in distilled water or red wine at 37°C. After 10 20 30 60 and 90 days, the color changes of resin cement were evaluated comparing to baseline color as ΔE*. Data were analyzed using 3-way ANOVA. Results Color change (ΔE*) of each resin cement was increased when time of immersion in distilled water or red wine was longer. When resin cements were immersed in distilled water, color changes from low to high were NxD, VvL, NxL, RvL, MxD, RuD respectively in the clear shade and RuD, NxD, NxL, VvL, RvL, MxD respectively in the white opaque shade. When resin cements were immersed in red wine, color changes from low to high were VvL, RvL, NxL, RuD, MxD, NxD respectively in the clear shade and RuD, VvL, RvL, NxL, NxD, MxD respectively in the white opaque shade. Conclusion Color stability of resin cements immersed in different solutions was varied among products in different times. From this study, light-cured resin cements had more color stability than dual-cured and self-etch, self-adhesive resin cements (except RuD white opaque shade). Clear shade resin cement tended to change in color more than white opaque shade. Resin cements immersed in red wine showed higher color change than those in distilled water.
