Summary:Introduction The aim of this study was to compare dental development in a group of children with mild-to-moderate hypodontia with a matched group. Methods A study group of 70 children (43 girls, 27 boys) with hypodontia, aged 5.3 to 12.5 years, was matched for race, age, and sex with 140 healthy, normal control subjects. The children’s dental ages were calculated by using a modified dental-age estimation method. Differences between dental and chronologic ages were analyzed by t tests, and the correlations between differences in dental and chronologic ages and the numbers of missing teeth were analyzed with the Spearman correlation test. Results Dental development in children with mild-to-moderate hypodontia was significantly delayed compared with the control group ( P
