Introduction: Molar-Incisal Hypomineralization (MIH) has become a public oral health concern in recent decades. This condition manifests as an enamel anomaly with multifactorial causes, associated with maternal and child diseases. From moderate degrees, porosities are distinguished that cause hypersensitivity and this leads to poor oral hygiene, which favors the accumulation of biofilm triggering dental caries that could mask MIH. The objective of this study was to estimate the prevalence, severity, and risk factors associated with MIH in an Ecuadorian population. Methods: A cross-sectional study in a sample of 290 children who underwent oral examinations and their 290 mothers who were administered a validated questionnaire; this was calculated using point estimates, confidence intervals, Student t-tests, Chi-square tests and Odds Ratio; with a significance level of 5 %. Results: 23.45 % of children presented MIH with a mild severity level and white coloration, occurring mostly in children aged 8 to 10 years. An association was detected between the mother's illness (p < 0.01), between the mother's antibiotic use and the presence of MIH in the child(p = 0.003). It was also found associated with respiratory diseases (p < 0.01), episodes of high fever (p < 0.01), antibiotic use by the child (p = 0.001), and the presence of measles, chickenpox, or rubella (p = 0.005). Conclusion: There is a high prevalence and low severity of MIH in the parish of Amaguaña, and it is related to various pre and postnatal causes.
