<br/><br/> The change in color and surface topography of resin composite following the immersion in different staining solutions and bleaching with ozonated gel and carbamide peroxide and repolishing. A total of 90 disk-shaped resin composite specimens were used in this study. They were reandomly divided into three groups of 30 specimens each according to the immersion solutions used i.e. tea, cols or artificial saliva
