Comparação entre os diferentes tipos de clareamento dental, quanto à eficácia e sensibilidade

Abstract

Dental bleaching is one of the most popular aesthetic procedures today, since the white smile has become one of the aesthetic standards. Thus, for this procedure being performed, it is up to the dentist to make a clinical evaluation for the correct diagnosis of dental structure, verifying which one is the best technique indicated in each case. The aim of this study was to evaluate the different types of dental bleaching, comparing them in terms of efficacy and sensitivity, by a literature review. According to the studies analyzed, at home, in office and combined dental bleaching techniques have the same clinical efficacy, that is, all techniques can achieve the same results in terms of color, but with variation in time and indication. As for sensitivity, it is observed that there is a tendency for this be greater in cases of office whitening and in the associated technique, when compared to homemade, due to the use of gels in higher concentrations. However, there are currently, whitening gels that have desensitizing substances in their formulation; or protocols that can be performed to reduce it. During office whitening, it is suggested to apply the gel in a single step in the total time recommended by the manufacturer. When it comes to acid gels, it is recommended to opt for multiple applications in short times, as the penetration of the gel into the pulp chamber is reduced. In addition, when opting for home whitening, preference should be given to the lowest concentration of Carbamide Peroxide gel, since it has the same effectiveness as those of higher concentrations, but presents a lower risk of developing tooth sensitivity.
