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.
