Abstract
Background: Predicting chronological age in adolescents and young adults can be crucial in Medico legal contexts
and the third molar is the only developing tooth during this period that used to determine chronological age.
The purpose of this study was to estimate the chronological age based on the stages of mandibular third-molar
development following the eight stages (A–H) method of Demirjian et al
Materials and methods: The sample consisted of 436 Iraqi adolescents and young adults subjects have been chosen
with known chronologic age (range, 14–24 years) and sex (162 males and 274 female), digital panoramic
radiograph had been taken for each examined subject, Demirjian’s grading has been used to assess third molar
development
Results: Statistically significant differences (P _ 0.05) in third-molar development between males and females were
revealed regarding the development stages D,E and F. Third-molar genesis was attained earlier in males than in
females. Statistical analysis showed a strong correlation between age and third-molar development for males (r 2 _
0.91) and for females (r 2 _ 0.87).
Conclusion: It was concluded that the use of mandibular third molar development stages using Demirjian method
can be considered as good valuable chronological age indicators in adolescents and young adults
