Introduction: Molar incisor hypo mineralization (MIH) is defined as extensive progressive enamel defects with a developmental origin. This study aimed to assess the prevalence and predictors of molar incisor hypo mineralization (MIH) in 6-12-year-old Iranian children 2022.
Materials and Methods: This cross-sectional study was conducted on all 6-12-year-old Iranian children residing in Ilam City, Iran, in 2022. For clinical oral examination, the surface of maxillary and mandibular permanent first molars and incisors was cleaned with a gauze and inspected and examined under adequate lighting and by using a dental explorer in wet conditions for the presence of opaque spots, surface degradation, and caries. The Chi-square and multiple logistic model were applied. Data were analyzed in SPSS V.24 at the level of 0.05 significance.
Results: Totally 1,016 children between 6-12 years participated in the study's first phase, 112 had MIH, yielding a prevalence rate of 11% for this condition. MIH was found in 53.2% of maxillary molars, 37.1% of mandibular molars, 9.7% of both maxillary and mandibular molars, 66% of maxillary incisors, 32% of mandibular incisors, and 2% of both maxillary and mandibular incisors. History of cesarean section (P<0.001), gestational diabetes (P=0.001), Chickenpox (P=0.041), Newborn jaundice (P<0.001), Otitis (P=0.036), Urinary tract infection (P=0.020), Antibiotic therapy (P<0.001) and Respiratory problems (P=0.047) had a positive association with MIH.
Conclusion: The prevalence of MIH was 11% in the study population, and cesarean section, gestational diabetes, medication intake during pregnancy, genetics, newborn jaundice, respiratory problems, otitis, urinary tract infection, antibiotic therapy, and chickenpox were significantly correlated with its occurrence.
