Efectividad del blanqueamiento dental con peróxido de hidrogeno al 35% sobre el sellado marginal de restauraciones con resinas compuestas.

Abstract

Tooth whitening with 35% hydrogen peroxide in the marginal sealing of restorations with composite resins is a common procedure in which several aspects must be understood and essentially addressed, such as their interaction and effectiveness at the interface of resinous materials. teeth with pre-existing composite resin restorations, in order to guarantee their durability and stability Objective: To evaluate the effectiveness of dental whitening with 35% hydrogen peroxide on the marginal sealing of composite resin restorations. Methodology: This research has a systematic review design, which includes pertinent information from academic or scientific articles that allow for answers and/or solutions to the research problem Results: the action of hydrogen peroxide results in a series of risks such as roughness on the enamel surfaces, as well as discrete and irregular increases in porosity. Conclusions: it was shown that despite being conservative and giving satisfactory results to patients, lightening agents may or may not alter the dental tissue, as well as the resin restorations and the union between them, weakening them and exposing them to post-operative sensitivity.
