Eficacia del aclaramiento dental mixto. Revisión de la literatura.

Abstract

Tooth whitening is relatively consertive alternative to restore esthetics to healthy teeth with minimal impact on dental structures. Objective: To determine the efficacy of mixed teeth whitening through a literature review. Materials and Methods: This investigation had a descriptive design. The research resulted in 46 articles in PubMed, 45 in SciELO, 68 in Elsevier, 1 in Cochrane, 3 in Researchgate, and 123 in Google Scholar; 36 papers were selected as the most relevant based on the inclusion and exclusion criteria. Results: The comparative studies by Faus V, Amengual J, Rezende M, Favaro J, Rodrigues J, Donasollo S, Nie J, Bersezio C, Knezovíc D, Vochikovski L found that the efficacy in achieving the desired final shade could be obtained without problem employing any tooth whitening protocol, the difference being in the application time required and the impact on the microhardness of the enamel structure. Conclusion: Professional whitening should use 35% hydrogen peroxide and 10% carbamide peroxide for home applications for 15 days, each lasting 2 hours. No differences were evidenced in the final color result regarding using these treatments separately or the mixed technique; however, the mixed technique reduced the time required to achieve these results.
