Teeth are used as a source of human identification. Age estimation through teeth plays an important role in this field.

In this study, delayed tooth development was observed in children with oligodontia compared to children without tooth agenesis.


The Haavikko method, which estimates teeth by using radiographic images of teeth, can be used in age determination, especially in children with tooth agenesis.


Aim: The aim of this study was to investigate tooth development according to chronological age in children with tooth agenesis and to determine whether the severity of tooth agenesis (hypodontia and oligodontia) has an effect on tooth development. Methods: In this retrospective study, the records of children diagnosed with hypodontia and oligodontia referred to the Department of Pediatric Dentistry between January 1, 1999 and January 1, 2018 were examined. The control group was matched with children diagnosed with oligodontia and hypodontia in terms of age and gender. A total of 288 children aged between 6-15 years were included in the study and the control, hypodontic and oligodontic groups were formed as Group I, Group II and Group III, respectively. Chronologic age was calculated and Haavikko’s method was used for dental age. The difference between chronological and dental ages was analyzed by ANOVA test and Tukey test was used for multiple comparisons. Results: There was a difference was determined between groups I and III in dental age determined by Haavikko’s method (p<0.05). When the difference between chronological age and dental age determined, it was found that in Group I, II, III, dental age was 0.71, 1.17, 1.88 years behind respectively chronological-age and this difference was statistically significant (p<0.05). Conclusions: In this study, delayed tooth development was observed in children with oligodontia compared to children without tooth agenesis.
