ABSTRACT
Anomalies in amelogenesis may be due to developmental defects or abnormalities in different components of developing teeth and can affect dental development. We compared dental development in a group of children with molar-incisor hypomineralization (MIH) with that in age- and sex-matched controls. Dental age was determined using panoramic radiographs of 105 children (59 girls, 46 boys) aged 7-11 years with severe MIH, and the findings were compared with those from 105 healthy age- and sex-matched controls. Although accelerated dental development was noted in the MIH group, the difference between the MIH and control groups was not statistically significant (P < 0.05). Furthermore, no relationship was found between number of affected teeth and the difference between dental and chronological age. In conclusion, children with severe MIH had slightly accelerated dental development as compared with controls.
