Resumo
Objective: To analyze the prevalence and severity of Molar Incisor Hypomineralization (MIH) and its relationship with dental caries in public school children in Manaus/AM. Material and Methods: Overall, 2,062 primary school children aged 6-10 years were examined to obtain MIH, DMFT, dmft and DDE indexes. The participation of five schools in each district of the city of Manaus was randomly determined, totaling 40 schools, and in each of them, two classes of each grade of elementary school in two shifts were selected, totaling 10 classes. Clinical examinations were conducted by two previously calibrated examiners in school environment under natural lighting. Data collected were submitted to descriptive statistical analysis by Chi-square, Fisher's Exact and Mann-Whitney tests at 5% significance level. Results: The prevalence of MIH in Manaus was 9.12% and no significant association with gender and age of schoolchildren was found. The mandibular arch was the most affected, with greater number of teeth being affected on the left side. The most frequently affected teeth were the mandibular permanent first molars, followed by maxillary counterparts and maxillary/mandibular central incisors. The most frequent diagnosis was mild MIH. The DMFT of children with MIH was 1.58 and dmft was 2.47, higher than those of the unaffected group. A correlation was found between DDE and MIH. Conclusion: Early diagnosis of MIH is imperative, since children affected show high risk for the development of dental caries.
