BACKGROUND/AIMS: The aim of this study was to evaluate the staining abilities of different beverages, the efficacy of two office bleaching agents and the effect of bleaching on the surface topography of maxillary incisors. MATERIALS AND METHODS: Sixty crowns of maxillary incisors were obtained and immersed in distilled water for 24 hours. After baseline color measurements were made, the specimens were divided into three groups according to three immersion solutions [Turkish coffee (TC), red wine (RW), and distilled water (DW)].
