Association between Molar Incisor Hypomineralization and Both Prenatal and Postnatal Factors in 8-10-Year-Old Children in Ardebil

خلاصه انگلیسی

Molar incisor hypo-mineralization is a malformation with a systemic background for which aetiology is not well defined. Prevalence of these lesions varies in different countries, but few studies have been conducted on its prevalence in the Iranian society. The aim of this study was to determine the prevalence of molar incisor hypo-mineralization among 8-10-year-old children in Ardabil and its relationship with prenatal and postnatal factors. METHODS In this analytical cross-sectional study, participants included 520 children from public schools of Ardabil. In the first stage, the frequency of MIH was determined by a clinical examination based on the index introduced by Tourino et al. Then, they were evaluated in two groups (with or without incisor hypo mineralization) to determine the causative factors. To collect information, a questionnaire including information about factors before and after birth was used. Data were analysed using SPSS 18 software. Chi-square and T-test and logistic regression were used to test the relationship between different factors. RESULTS The prevalence of molar-incisor hypo mineralization in children aged 8-10-year-old in Ardabil was estimated to be 24 %. The results also showed that there is a significant relationship between latarerp and postnatal factors (p < 0.05). CONCLUSIONS Due to the high prevalence of MIH in Ardabil, preventive measures, informing the parents and periodic examination of the teeth are recommended.
