The choice of treatment depends on the type and severity of the defect. The objective of this work was to present a micro-invasive treatment option for a type of DDE. This report addresses a 14-year-old patient with a complaint about the color of her teeth. Mainly in element 11, which had a white, smooth, and opaque spot in its middle third. Upon clinical and radiographic examination, Molar Incisor Hypomineralisation (MIH) was diagnosed. Because of her age, micro-invasive treatments such as tooth whitening and the application of resin infiltrant (ICON – DMG) were proposed. Initially, an in-office bleaching session (35% hydrogen peroxide) was performed followed by home bleaching (10% carbamide peroxide) for 3 weeks. The initial color was found using the Vita scale, was close to A2 and the result obtained after bleaching was close to B1. Two weeks after the bleaching process, the resin infiltrant was applied to mask the stain. The results obtained were highly satisfactory. Resin infiltration to mask DDE is a minimally invasive and immediate approach that can mask diffuse opacities improving esthetics.
