METHODOLOGY : The study population comprised of 250 ; 6 – 12 year olds , from three schools in Mangalore , Karnataka . Subjects were evaluated clinically by one examiner in oad daylight and inspected and scored for hypomineralized molars and incisors using EAPD criteria cited by Ghanim et al . Statistical analyses were performed using ANOVA , TUKEY HSD test. RESULT: Fourty four (17.2%) children showed MIH. White creamy opacities opacities were the most frequent enamel defect . There was no statistical significant difference in MIH seen among boys and girls CONCLUSION : The prevalence of MIH in a group of Mangalorean children was 17.2%.
