MOLAR-INCISOR HYPOMINERALIZATION: A LITERATURE REVIEW

Abstract

This article sought to investigate molar-incisor hypomineralization (MIH), a condition that affects the formation of tooth enamel, making teeth more susceptible to cavities and fractures. Through an integrative literature review, recent studies from different databases, such as PubMed and Scopus, published between 2020 and 2024 were analyzed. The selection criteria included works that addressed the etiology, diagnosis, prevalence and clinical impact of MIH. The research highlights that genetic, environmental factors and exposure to medications during childhood are determining factors in the development of MIH. The main results show that hypomineralization causes damage to oral health and negatively impacts the quality of life of affected children, in addition to representing a challenge for dental practice. Studies indicate that early diagnoses and interventions are essential to avoid serious problems in children's teeth. Furthermore, there is a need for greater training of professionals, especially in regions with a high prevalence of the condition. It is concluded that advances in understanding about MIH enable the development of prevention strategies aimed at reducing the risk of cavities and improving the prognosis of child patients.
