The Effect of Color Selection on the Color Stability of the Resin Cement

Abstract

Objective: The aim of this study was to determine effect of shade selection on resin cement's color stability. MaterialsandMethods:Ten resin cement samples in dimensions of 10 mm diameter and 2 mm thickness for each group [group 1: Translucent base and translucent catalyst, group 2: Bleach XL (B1) base and yellow (A3) catalyst, group 3: White (A1) base and A3 catalyst] totally 30 samples were prepared. Color coordinates of each sample were recorded after polymerization and 5000 thermal cycles. Color variation (?E) was calculated for each sample and statistical analyses were performed. Results: The lowest ?E values were obtained for group 1. Group 2 showed higher ?E values than group 3 however there were no statistical difference. Conclusion: Translucent base and translucent catalyst mixture showed clinically acceptable color stability while B1 base and A3 catalyst and A1 base and A3 catalyst mixtures did not show clinically acceptable color stability. Shade of the resin cement partially effected its color stability.
