This study was conducted in order to evaluate the prevalence and severity of Molar Incisor Hypomineralization (MIH), the prevalence of dental caries and the relationship between these two changes in children from 8 to 12 years old in the city of Patrocínio Paulista, São Paulo State, and also to check with a validated questionnaire their impact in the quality of life of these children. From a clinical exam, 248 children were evaluated by a previously calibrated examiner for the presence of MIH (according to the EDPS criteria) and DC (according to WHO criteria). Two quality of life questionnaires related to oral health (CPQ8-10 e CPQ11-14) were applied across all samples. The results were presented in tables and graphics of frequency distributions and tested by Fischer, Chi-squared Distribution, Mann Whitney and Kruskal-Wallis Tests. For all analysis, the significance was considered when p<0.05. Among the 248 evaluated children, 35 had MIH, obtaining a 14% prevalence. Regarding to the severity, 19 children had light MIH, while 16 had severe MIH. The DMFT Index for children from 8 to 12 years old of the city of Patrocínio Paulista was 1.04. When evaluating the severity of each individual child affected by severe MHI, it was observed that 50% had two affected quadrants, and only one had MHI in four quadrants. The prevalence of dental caries was 67%, and the value of DMFT for children from 8 to 12 years old, in the city of Patrocínio Paulista, was 1.04. An association between MIH and DC was observed, since children with MIH showed significantly higher value of medium DMFT (1.66) than those children who did not show the change in tooth enamel (0.94) (p = 0,013). Regarding to the oral health impact on quality of life, children with DC, followed by those who had MIH and DC, presented higher values than those who showed no change and those who had only MIH. The most affected variable of the questionnaire was oral symptoms and functional limitations in all studied groups. From the 248 children, only 8 had no impact of studied oral changes in the quality of life. It is believed that more prevention actions and health promotion must be implemented in the city so that the prevalence of these changes are dwindling.
