Abstract
Introduction: Molar Incisor Hypomineralization (MIH) describes a developmental enamel defect that affects one or more permanent molars, with or without incisor involvement. Early diagnosis facilitates treatment procedures for dentists and patients. This study aimed to investigate the prevalence of MIH in 6- to 8-year-old children in Isfahan.
Materials and Methods: In this cross-sectional study, 651 children aged 6 to 8 years (326 girls and 325 boys) from Isfahan city were randomly selected from 6 education districts during the 2019-2020 academic year. The established criteria of the European Academy of Pediatric Dentistry were used to assess the prevalence of molar incisor hypomineralization. The prevalence and relationship between this defect and criteria such as gender, age, parental education level, and type of school were investigated. Data were analyzed using Independent T-tests, Mann-Whitney, and Chi-square (α = 0.05).
Results: The prevalence of MIH in Isfahan was 21.2%. None of the demographic factors, such as age, sex, type of school, and parental education level, were associated with the prevalence of MIH. DMFT and dmft were higher in these children than in children without enamel defects. The highest frequency of lesions was related to white-cream opacities without enamel fractures. The most severe type of MIH was seen more in molar teeth.
Conclusion: MIH is highly prevalent in Isfahan, but most lesions are mild, and preventive measures, increased awareness, and regular dental examinations in the early years of permanent tooth eruption are very helpful.
