Prevalence of molar incisor hypomineralization (MIH) and its association with some risk factors in group of children attending two specialized dental centers in Erbil city
Keywords:age groups, dental enamel hypoplasia, etiology
Background and objectives: Molar incisor hypomineralization (MIH) is frequent in children and the etiology is different. The study was conducted to determine the prevalence, and risk factors of MIH and to investigate the relationship between the severity of the defect in the teeth affected by MIH and the risk factors.
Method: A total of 361 children in the age range of 7–12 years participated in the study. The sample was taken from a group of children attending two specialized dental centers in Erbil City. The participating children were examined for MIH using the European Academy of Pediatric Dentistry Criteria. The children’s parents were asked about the child’s pre, peri-, and postnatal condition utilizing a structured and validated questionnaire.
Results: A total of 99 children (40 males and 59 females) were affected with MIH, with a prevalence of 27.4%. the most common defect was demarcated opacity, among all analyzed etiological factors, only diabetes was found to be significantly associated with MIH in children (p = 0.020).
Conclusion: diabetes was the only etiological factor that showed a significant association with MIH in the studied group of children.
