The tooth has become very popular among clinicians and patients. Two methods are known; one that takes the patient at- home and another at-office. The aim of the study was to determine analyze the effect of two bleaching agents on the enamel surface microhardness. Two bleaching agents are used; 35% Hydrogen Peroxide and 35% Carbamide Peroxide.Twenty-five bovine teeth were sectioned longitudinally to obtain three fragments were used; one for control and the other two for each bleaching agent. The microhardness was measured using a Leco Hardness LMV-50V model, with a load of 20gf. The results showed a significant decrease in enamel microhardness relative to 35% Hydrogen Peroxide compared to 35% Carbamide Peroxide.
