AGE ESTIMATION FROM ROOT DIAMETER AND ROOT CANAL DIAMETER OF MAXILLARY CENTRAL INCISORS IN CHENNAI POPULATION USING CONE-BEAM COMPUTED TOMOGRAPHY

Abstract

The aim of this study is to evaluate the possibility of age estimation from root diameter and root canal diameter of maxillary central incisors using 100 CBCT images collected from the Department of Radiology, Saveetha Dental College.A total of 100 cone-beam computed tomography images were taken from the Department of Radiology, Saveetha Dental College and Hospitals, consisting of 50 males and 50 females aged between 15 and 64 years with individuals’ chronological age.Group I (15-24 years), group II (25-34 years), group III (35-44 years), group IV (45-54 years), group V (55-64 years).The points used to locate root canal diameter and root diameter in maxillary central incisors were marked. Root diameter and root canal diameter were measured and the ratios of root canal diameter and root diameter were calculated. Correlation coefficient and linear regression analysis was performed for both the sexes in the Chennai population. Root canal diameter/root diameter ratios showed higher correlation with age than root diameter, which was used to estimate age for both sex in
different age groups from 15 to 64 years.The SEE ranged from 1.67 to 3.70 years for age estimation from total sample. Dental age estimation is possible using cone-beam computed tomography from root diameter and root canal diameter of maxillary central incisors in the South Indian population.
