Uso da resina infiltrante no tratamento minimamente invasivo de manchas brancas em esmalte dental: Uma revisão bibliográfica

Abstract

The resin infiltration technique was introduced as an alternative therapeutic approach based on the penetration of a low viscosity resin, with a high penetration coefficient, in the intercrystalline region of the porous spaces of a white spot lesion. The purpose of this literature review was to report and discuss the use of fluid resin infiltration in the treatment of white spots on the buccal surface of tooth enamel. The databases Google Scholar, Pubmed and Scielo were consulted between 2010/2019. The search was conducted in English and used the following keywords: color masking, dental fluorosis, hypomineralization, microabrasion, resin infiltration, tooth whitening, white defects of enamel and white spot lesions, which resulted in a total of 62 (sixty-two) scientific articles. After preliminary analysis, according to inclusion and exclusion criteria, this number was reduced to 18 (eighteen) scientific articles. It was found that the understanding of the etiology and depth of the white spot lesion is fundamental for the indication and color masking of the infiltration resin technique. In superficial lesions, the use of infiltration resin alone was able to solve dental staining. In situations of deeper bruises, it was found that other procedures, such as microabrasion or tooth whitening, must be associated to obtain a better clinical result. It was noted that medium and long term clinical studies are necessary to better evaluate the clinical behavior/success of the resin inflitration.
