Personal data, as well as the medical history and any previous dental history were recorded for each child in the diagnostic chart. Clinical examination was performed in the school laboratory or an empty class using day light. The first permanent molars and permanent incisors were examined to detect the presence of MIH and its severity based on European Academy of Pediatric Dentistry criteria and scores were recorded in the diagnostic chart.
Results: A group of Egyptian students were examined in Fayoum governorate schools with the mean age of (11.27±1.20) years, 263(58.4%) were boys and 187(41.6%) were girls, 22 students were diagnosed with MIH and MIH prevalence was (4.9%). Regarding MIH severity, out of all MIH affected teeth (65.7%) had mild MIH, (12.9%) had moderate MIH and (21.4%) had severe MIH.
Conclusion: Upper right central incisor was the most prevalent tooth with MIH. The most prevalent degree of MIH severity was mild, followed by severe, then moderate. White or creamy demarcated opacities was the most prevalent enamel defect form.
