Tratamento minimamente invasivo para hipomineralização molar-incisivo: relato de caso

Abstract

Molar-Incisor Hypomineralization (MIH) is a dental enamel development disorder of unknown etiology that affects the first permanent molars as well as the incisors of the same dentition, and may also be related to the canines and second molars. The objective of this study was to describe and analyze the efficacy of the combination of the in-office bleaching technique, with high concentration hydrogen peroxide, and assisted bleaching, with low concentration carbamide peroxide, and Icon resin infiltration (DMG) for the treatment of teeth with hypomineralized stains. For the combined bleaching technique, the Whiteness Max 35% hydrogen peroxide gel (FGM, Joinville, SC, Brazil) was applied by the professional in 4 sessions with a seven-day interval between them. In the interval between these sessions, the patient applied the carbamide peroxide gel 10% (FGM, Joinville, SC, Brazil) through a customized silicone tray. The color was checked weekly and, after the whitening technique was completed, a whitening effect was obtained, evidenced on the color scale, from B2 to B1. Following the whitening technique, the resin infiltrant Icon (Icon-DMG®) was applied to the hypomineralized spots. Based on this case report, it was possible to conclude that, within the limitations of this study, the combination of the presented techniques, home and in-office whitening associated with resin infiltration, was effective in the aesthetic treatment of hypomineralized white spots, making them clinically imperceptible, providing, in addition to favorable aesthetic results, an improvement in the patient's self-esteem and confidence. In this context, the importance of developing an individualized treatment, based on the clinical characteristics of each patient, in order to provide a more efficient protocol, is highlighted.
