Background: The purpose of this study was to estimate the prevalence of molar incisor Hypomineralisation (MIH) in a group of school children aged 7 to 12 years, in sari.
Materials and Methods: 700 school children (350 males and 350 females) were randomly selected for participation in this descriptive cross-sectional study. The prevalence of MIH was, initially, determined through clinical examination. The participants with MIH were also interviewed, and Related Data was recorded in questionnaires filled by the examiner. The data of study was analyzed using the Chi-square, Fisher’s exact, and Mann-Whitney U tests through SPSS version 17. P-vale less than 0.05 was considered statistically significant.
Results: The prevalence of MIH was 20.2 % (n =142). Prevalence rate calculated in the studied group was 21.1% (males=74) and 19.4% (females=68).There was no significant difference between the two genders in terms of the prevalence and intensity of the MIH (P=0.4).
Conclusion: The results revealed that MIH is of moderate prevalence in Sari primary schools, and its prevalence is not significantly associated with gender.
