hypomineralization amongst a Risk factors in the occurrence of molar – incisor group of Iraqi children

Background. Despite the worldwide increasing interest in the prevalence studies of molar–incisor hypomineralization (MIH), there is still insufficient evidence to verify the aetiological factors of this condition. Aims. To investigate risk factors involved in the development of MIH in a group of school-aged Iraqi children. Design. Sevento nine-year-old school children (823 of 1000 eligible, response rate of 82.3%) had their first permanent molars and incisors evaluated using the European Academy of Paediatric Dentistry evaluation criteria for MIH. Mothers completed a medical history questionnaire-based interview performed in the schools by a trained examiner.
