TREATMENT OF CARIOUS LESIONS IN TEETH WITH MOLAR-INCISOR HYPOMINERALIZATION (MIH)

Abstract

Molar-Incisor Hypomineralization (MIH) is a defect in the quality of dental enamel of systemic origin that affects the first permanent molars and also the permanent incisors, affecting these teeth either together or separately. It is characterized by demarcated opacities ranging in color from white to brown, high enamel porosity, and hypersensitivity, which favor the development of carious lesions. This article aimed to analyze the current scientific evidence regarding preventive strategies and therapeutic approaches used in the management of MIH. This is a literature review based on a bibliographic search conducted in the PubMed and SciELO databases and in guidelines from professional organizations, using scientific articles, clinical trials, and reference manuals published between 2021 and 2026. For preventive and restorative purposes, the application of pit and fissure sealants (glass ionomer-based and resin-based), remineralizing agents, and the use of glass ionomer cement (GIC) stand out due to its biocompatibility, chemical adhesion, and continuous fluoride release
