Objective: To assess the prevalence, clinical characteristics and risk factors associated with MIH defects, in children aged 8 - 12 years of a sub district in Thiruvananthapuram, Kerala.
Study Design: 1200 school children in the age group of 8 to 12 were examined from Nedumangad educational sub-district of Thiruvananthapuram, Kerala. The first permanent molar and permanent incisors were examined for demarcated opacities, post-eruptive breakdown, atypical restorations, and extracted first permanent molar. Children were considered to have MIH if one or more first permanent molar with or without involvement of incisors met the diagnostic criteria. Parents of those children who were diagnosed with MIH and an equal number of socio-demographically matched control population, completed a questionnaire which elicited presence of various etiological factors associated with MIH.
Results and Conclusion: MIH is observed in about 5.5% of the children examined. The occurrence of MIH is significantly associated with medical problems during pregnancy, medical problems or difficulties during delivery for mother, birth time complications in child, hypoxia at time of birth, maternal diabetes after delivery, use of incubator soon after delivery of the child and history of hospitalization due to high fever during the first 3 years of childs life.
