A review of the literature on the evolution and consequent importance of the improvement whitening techniques. Methods: Two patients treated at the dentistry clinic of Unorp, where the office bleaching carried out with the agents based on hydrogen peroxide 35% and carbamide peroxide 37% applied with the same technique. For this, the patients' dental arches divided in half with the placement of a polyester strip between the proximals of the central incisors for dividing the hemiarcs to start the bleaching technique. The right and left quadrants then received the corresponding whitening gel. Conclusion: There was no visual difference between the bleaching gels employed, thus, both materials have good clinical results.
