Monaghan et al14 reported that 30% hydrogen peroxide bleaching produced a significant color change in freshly prepared specimens of different composites. On the other hand, Hubbezoglu et al15 found that bleaching with 35% hydrogen peroxide resulted in composite resin color change values of a lesser magnitude. However, the ability of bleaching to remove acquired stains has not, as yet, been fully investigated. With regards to surface properties, some reports indicated that bleaching agents containing 30 to 35% hydrogen peroxide did not affect the surface texture as revealed by profilometric analysis.16,17 Nevertheless, analysis of surface reflectance showed significant changes in microfilled and hybrid composites.16
