Abstract
The aim of this study was to compare the color stability of 3 proprietary carbamide peroxide bleaching agents on composite resins. Specimens were prepared with a polytetrafluoroethylene plate. After initial color measurements, bleaching agents were applied to each composite resin for 2 weeks. Second color measurements were made. Tested specimens including control group were immersed into distilled water for a - 4 month follow-up period. Third and fourth color measurements were made again after 2 weeks and 4 months of follow-up period. Friedman (p .01), Kruskal Wallis (p .05) and Wilcoxon Tests were used for statistically evaluation. The most significant color change was seen at the Ormocer group (p .011). The most significant color change ΔE values were obtained for the Ormocer-Voco group and color changes remained stable after 4 months of immersion in distilled water. Slight color changes values were obtained for nanohybrid and fine particle hybrid composite resins.
