Análise comparativa de técnicas minimamente invasivas no tratamento de manchas por fluorose

Abstract

Fluorosis arises in the teeth formation phase and its main characteristics are white or brownish stains on the dental enamel, which can interfere with the aesthetics of the smile. The aim of this study was to analyze the effectiveness of different forms of treatment for fluorosis and to compare the surface roughness of the enamel before and after each technique was conducted. The treatment was carried out after tooth whitening in a clinical case of split mouth design consisting of three different techniques: microabrasion with pumice and phosphoric acid 37%; microabrasion with Whiteness RM (FGM); resin infiltration with Icon (DMG). The clinical result was satisfactory, and all techniques diminished the appearance of white sptos, making them imperceptible, thus improving dental aesthetics. However, a comparative analysis of the surface roughness showed that the use of the infiltrating resin Icon resulted in increased roughness values when compared to the other microabrasion techniques. Within the limitations of this study, It was concluded that all techniques were effective in the aesthetic treatment of fluorosis stains, although the teeth treated with the Icon infiltrating agent increased the final roughness of the enamel.
