| description | Introduction: Forensic dental age estimation plays a vital role
in determining the identity of a deceased individual. There are
numerous dental age estimation methods available to estimate
dental age using radiographs based on tooth maturation.
Aim: To compare Nolla’s method, Cameriere’s Indian-specific
method, and Acharya’s Indian-specific regression formula
in estimating dental age in the Puducherry and Cuddalore
populations of South India.
Materials and Methods: This retrospective study was conducted
in the Department of Oral Medicine and Radiology at the Indira
Gandhi Institute of Dental Sciences, Puducherry, India, between
January 2021 and October 2022. The study included 448
panoramic radiographs (202 males and 246 females) of individuals
aged between six and 17 years. Chronological age was recorded
based on the subject’s date of birth. Dental age was estimated
using Nolla’s method, Acharya’s Indian-specific regression formula,
and Cameriere’s Indian-specific method. Two qualified and
experienced oral radiologists evaluated all the samples to assess
their reliability. Data were analysed using descriptive statistics, the
Pearson’s correlation coefficient, and Student’s t-test.
Results: Nolla’s method (excluding the third molar) revealed a
mean age of 13.52±3.15 years, while Nolla’s method (including
the third molar) revealed a mean age of 12.81±2.84 years.
Acharya’s Indian-specific method revealed a mean age of
15.08±2.92 years, and Cameriere’s Indian-specific regression
formula revealed a mean age of 11.51±2.19 years. The results
showed that the age estimated by Nolla’s method (including
the third molar) had a p-value of 0.93 (>0.05), indicating no
significant differences between the estimated dental age and
chronological age. The r-values for Acharya’s Indian-specific
regression formula, Nolla’s method (excluding the third molar),
Nolla’s method (including the third molar), and Cameriere’s
Indian-specific method were found to be 0.682, 0.885, 0.847,
and 0.849, respectively, indicating a strong positive correlation
among the age estimation methods.
Conclusion: Nolla’s method (including the third molar) was
found to be the most accurate method for dental age estimation
when compared with the other three methods in the Puducherry
and Cuddalore populations. |
