Objective: This work aims to determine prevalence and consequences of Molar Incisor Hypomineralization in the city of Ouro Verde – SP. Methodology: 457 children, students from the municipal school EMEF Julia Roseira Jerônimo were examined, aging from 7 to 11 years old. Clinical examinations for the diagnosis were performed by a single trained and calibrated examiner using the criteria proposed by the European Academy of Pediatric Dentistry (EAPD, 2009) using natural light and wood spathulas. Result: The index found in the city was 15% of students (79 affected children) and only one case with sensitivity. Conclusion: prevalence was significative, although symptoms related were rare.
