Abstract

Molar-Incisor Hypomineralization (MIH) is a development disturbance that affects first permanent molars and incisors, with prevalence ranges from 3,6 to 25%. In MIH, hypomineralized dental enamel is fragile and can break easily leading exposed dentin and causing dental sensitivity and caries lesions. The etiological factors are frequently associated with childhood diseases during the first three years of life. The treatment depends of the severity of the case, including from direct restorations to tooth extractions. The aim of this study will be to describe the frequency and severity of MIH in children from public and private schools, at Araraquara/SP, Brazil. Tooth examinations will be performed in 1,036 schoolchildren, with age range from 6 to 10 years, to register MIH signs, DMF-T index (decayed, missed, filled permanent tooth), def-t index (decayed, extracted, filled deciduous tooth) and DDE index (developmental defects of the enamel). Child will be asked about hypomineralization symptoms and a questionary will be send to parents to identify the socio-economics profile and to obtain informations about child medical history in the first year of life. The data will be statistically analysed on significance level at 0,05.
