Estimation of age in an individual whether living or dead has received a considerable attention in forensic science. Recently, the dental maturation system has gained impetus as a valuable index for age estimation, as teeth are more resistant to most peri- and post mortem changes. Radiological age estimation using teeth rely on developmental stages of teeth especially in children while in adults; the continuous deposition of secondary dentin throughout life is depicted by reduction in pulp area. Through this paper we bring across a radiological study to estimate the age of an individual via 3 computer aided software’s on maxillary central incisor. 30 periapical radiographs of individual aged ≥ 12 to ≤ 30 years were taken using radiovisiography (RVG). Radiographic images were processed using the software; data was statistically analyzed to compare the age. There was no statistical significant difference in age calculated by Adobe Photoshop and Auto CAD, Adobe Photoshop p=0.432 and Auto CAD p=0.004; though there was significant statistical difference in age calculated by Image J, p<0.001. It was concluded that pulp/tooth area ratios of maxillary central incisor are reliable for estimation of age and AutoCAD gave the most accurate results.
