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

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