Molar-Incisor Hypomineralization (MIH) is a hypomineralization of systemic origin of first permanent molars and incisors. In this condition, hipomineralized dental enamel is fragile and soft and can break easily, leading the dentin exposed and causing problems like dental sensitivity and progression of caries lesions. MIH is frequently misinterpreted as fluorosis or amelogenesis imperfecta and the prevalence ranges from 3,6 to 25%. Several aetiological factors are mentioned as the cause of the condition and they are frequently associated with childhood diseases during the first three years of life. The treatment includes the use of adhesive materials for restorative procedures, or even the extraction of the teeth, according to the severity of the case. UNITERMS: dental enamel; dental enamel hypoplasia; incisor; molar.
