An analysis by scanning electron microscopy was undertaken to investigate the effects of bleaching on enamel‐cementum surface morphology. Teeth were investigated in five groups: control; vital bleached for 5, 15, and 30 days; and 37 percent phosphoric acid gel etched for 20 seconds. Only the gel‐etched group exhibited etching patterns. Shade change in vital bleached teeth was noted in the group vital bleached for 30 days.
