MOLAR-INCCISOR HYPO MINERALIZATION AND ITS EFFECTS ON THE MAINTENANCE OF THE FIRST PERMANENT MOLARS

Abstract

This article aimed to discuss the effects of Molar-Incisor Hypomineralization and its impact on the maintenance of first permanent molars. With that in mind, the central research question is to understand how MIH influences the early loss of first permanent molars. The main goal is to describe the clinical impact of MIH on this early loss. The specific objectives are to identify and understand its clinical characteristics, cover its causes and effects on oral health, and discuss the main available treatment options. The methodology adopted a descriptive and qualitative approach, based on a literature review conducted in the scientific databases PubMed, SciELO, and the Virtual Health Library (VHL). The results show that affected teeth have white, yellowish, or brown opacities, porous enamel, low resistance, and a high incidence of post-eruptive fractures. There is an association with higher susceptibility to dental cavities, sensitivity, and difficulty with oral hygiene due to pain. In addition, there is a higher rate of restorative failures, greater complexity in clinical procedures, and, in severe cases, the need for tooth extraction, increasing the likelihood of early loss of the first permanent molars.
