Introduction: For various forensic investigations of both living
and dead individuals, the knowledge of the actual age or date
of birth of the subject is of utmost importance. In recent years,
age estimation has gained importance for a variety of reasons,
including identifying criminal and legal responsibility, and for
many other social events such as birth certificate, marriage,
beginning a job, joining the army and retirement. Developing
teeth are used to assess maturity and estimate age in number
of disciplines; however the accuracy of different methods has
not been assessed systematically. The aim of this study was to
determine the accuracy of four dental age estimation methods.
Materials and Methods: Digital Orthopantomographs (OPGS)
of South Indian children between the ages of 6 and 16 y who
visited the department of Department of Oral medicine and
Radiology of GITAM Dental College, Visakhapatnam, Andhra
Pradesh, India with similar ethnic origin were assessed. Dental
age was calculated using Demirjian, Willems, Nolla, and adopted
Haavikko methods and the difference between estimated dental
age and chronological age were compared with paired t-test
and Wilcoxon signed rank test.
Results: An overestimation of the dental age was observed by
using Demirjian and Nolla methods (0.1±1.63, 0.47±0.83 years
in total sample respectively) and an underestimation of dental
age was observed by using Willems and Haavikko methods
(-0.4±1.53, -2.9±1.41 years respectively in total sample).
Conclusion: Nolla’s method was more accurate in estimating
dental age compared to other methods. Moreover, all the four
methods were found to be reliable in estimating age of individuals
of unknown chronological age in South Indian children.
