Molar Incisor Hypomineralization (MIH) is a qualitative alteration in the formation of tooth structure that can cause the loss of large areas of tooth structure. The prevalence of Molar Incisor Hypomineralization varies widely in the world and there have been few epidemiological studies conducted in Latin America and specifically in Ecuador. Objective: To determine the prevalence and severity of (MIH) and its association with dental caries in children from 8 to 10 years old of public primary schools in Las Casas neighborhood. Material and methods: Corresponds to a cross-sectional study in which 366 schoolchildren between 8 and 10 years old were evaluated who attended to the public schools in Las Casas neighborhood, which had all the first molars and permanent incisors completely erupted. The variables were age, gender, education of the representative, occupation of the representative, frequency of brushing; the clinical variables that were evaluated were HIM using the criteria described by Mathu-Muju & Wright; and dental caries, using the International Caries Detection and Assessment System index (ICDAS II). Results: The prevalence of molar incisor hypomineralization in the total sample was 21.3% when it was associating with dental caries it was detected that 2.2% (n = 8) of schoolchildren without caries presented MIH, a difference of 9.3% (n = 34) of schoolchildren who presented caries with detectable cavities and 9.8% (n = 36) of children with incipient lesions had MIH. Conclusion: The presence of MIH was high and was associated with dental caries. Schoolchildren with MIH presented a higher risk of developing caries.
