We present a study "in vitro" of the effect of bleaching agents on dental surfaces using the "Walking bleaching technique". We found that hydrogen peroxide bleached more quickly than carbamide although, after a period of six weeks, the results were the same as far as whitening was concerned. In the scanning electron microscope we observed significantly different changes in each case. Carbamide caused a regular and uniform opening of the enamel prisms of the surface while hydrogen peroxide produced more severe superficial destruction with the appearance of patterning similar to the acid etching, and the presence of some crystalline areas emerging from the body of the prisms.
