Methods: A total of 3084 children aged eight to twelve years diagnosed with MIH were recruited in this study. Clinical examination was carried out on the dental chair, in day light to assess the prevalence and severity of MIH and scores were recorded in patent assessment chart. Categorical data were presented as frequencies (n) and percentages (%) and were analyzed utilizing Chi Square test. Results: Among these children, 48.5% were males and 51.5% were females, 58.1% were ten years old or younger and 41.9% were above the age of ten. The number of examined teeth was 37008; 66.7% were incisors and 33.3% were molars. There was no significant association between age and severity of MIH while there was a significant weak association between severity of MIH and sex.
