With the purpose of identifying the relationship between dental caries and possible etiologic factors, prevalence, severity of molar-incisor hypomineralization (MIH), 1,124 schoolchildren from rural and urban area in Manaus, Amazonas, were examined. We used the criteria established EAPD and to diagnose MIH and the DMFT and deft indices to diagnose dental caries. A semi-structured questionnaire was completed by the mothers to investigate gestational health and the child's health during the first years of life, as well as the socioeconomic and demographic factors. Data were tabulated and analyzed using descriptive statistics and the chi-square test, Mann-Whitney test, backward method, and odds ratio were used to correlate the variables. The prevalence of MIH in Manaus was 8.9%, not being related to housing area, gender or age of the children diagnosed (p>0,05). Dental alteration was more frequently observed in the lower arch and the first molars were the most affected. The most frequent diagnosis was mild severity. Dental caries experience was higher in rural areas, but in Urban area there was a close relationship between this and the HMI. No association was observed among MIH, socioeconomic factors, and the medical history of the mother, however, a significant association was found among prematurity (p = 0.01), jaundice or lack of oxygen after birth (p = 0.04). MIH is a severe problem for both the children affected and the health professionals due to the complex signs and symptoms, requiring prospective studies to elucidate the etiology.
