Age Estimation Using Root Canal Diameter and Root Diameter of Maxillary Central Incisors In A Subset Of Indian Population- A CBCT STUDY

Abstract

Introduction-Age estimation and identification in forensic is quite difficult sometimes still it is of great importance. Many methods have been introduced for the estimation of age through teeth analysis. The aim of the present study is to derive a regression formula for determination of age from root diameter and root canal diameter of maxillary central incisors in a subset of Indian population using Cone Beam Computed Tomography.

Material And Methods- This is a retrospective study involving the evaluation of 200 CBCT scans of permanent maxillary central incisors of both males and females between the age group of 15 and 75 years.

Result- The findings of this study revealed that the ratio of root canal diameter to root diameter is an age-independent variable that can be used to accurately estimate age in the Indian population. Root canal diameter/root diameter ratios showed a statistically significant correlation with age in correlation and regression analysis. (For the right side, r =0.31 and P0.0001, and for the left side, r = 0.33 and P0.0001). As a result, both the right and left sides were equally good at estimating age.

Conclusion- CBCT-based dental age estimation is a reliable method for determining age. The equation developed in this study is more accurate for estimating age in older age groups, and less accurate in the younger population. . However, more research with a larger sample size and different types of teeth is needed to improve age estimation accuracy.
