Dental Age Assessment Using Demirjian’s Method in Patients Visiting A Dental School in Uttrakhand
Background: Age estimation forms one of the most important sub-disciplines of forensic sciences and is of paramount importance in medico-legal issues.
Material and Methods: The study comprised 200 subjects aged 14 to 24 years. By purposive sampling method the study subjects were divided into 10 groups starting from 14 years to 24 years with a class interval of 1 year ( e.g. Group I:- 14.01- 14.99 years, Group II:- 15.01- 15.99 years…… Group X: - 23.01- 23.99 years). Each age group consisted of 20 subjects with equal distribution of 10 subjects in both genders. Chaillet and Demirjian’s method with Acharya’s formula was used to compare the chronological and the estimated dental age.
Results: The study showed a significant p-value (p< 0.005) in all the age groups in both the genders except for group v (18.01-18.99) in males and group III (16.01-16.99) and group V (18.01-18.99) in females. Also, the difference in the estimated dental age varied between + 4.18 years and – 2.02 years for males and +4.08 years and – 0.20 years in females. The results depicted an overall underestimation of the dental age by 0.60 years in males and 1.26 years in females.
Conclusion: we concluded that Chaillet and Demirjian’s radiographic method with Acharya’s formula can be a reliable method in the assessment of dental age in the mentioned study group consisting of the Uttarakhand population.
