Background: Radiology plays an important role in human age estimation and dental radiography being the most simple, non-destructive technique. Dental age estimation has been widely used to determine the chronological age of adolescents and young adults.
Materials and Methods: A total of 510 digital orthopantomograms of 227 females and 283 males aged between 9 and 25 years were taken, and third molar development was evaluated by Demirjian's tooth mineralization stages (statistical analysis using Mann- Whitney U test was performed to compare the differences in the mineralization stages of males and females and between maxilla and mandible). Comparison of male and females with mean stages in maxilla and mandible were done using Mann-Whitney U test. Probabilities of individuals being older than 10, 12, 14, 16, 18, 20, 22, 24 years were also estimated.
Results: Males attained formation Stage H (the apical end of the root canal is completely closed) earlier than females, whereas females attained Stage G earlier than males. Maxillary left molar developed earlier than mandibular left molar in males. 100% probability was seen in Stage H for both maxilla and mandible.
Conclusion: The Demirjian method is most reliable for age assessment using third molar mineralization stages. |
