Variation in SPC/STC Ratio as an Indicator of Age: A Computer-aided Forensic Odontology

Abstract

Aim: The aim of the present study was to evaluate the change in pulp width at the level of cemento-enamel junction and its correlation to different age groups Materials and methods: It is a retrospective study in which we are going to see the changes in pulp width as age increases. Ground section of 100 extracted maxillary first premolars were made up to the midpulpal area in labiolingual plane. The correlation of different age group with reduction in ratio of score of pulp width (SPC ) and score of tooth width (STC ) at cemento-enamel junction was done. All teeth were examined under stereomicroscope then SPC and STC were measured by Leica Qwin software. Results: Pearson correlation between SPC/STC ratio with different age group was found to be statistically significant. So, measurement of amount of secondary dentin seems to be reliable and rapid method in forensic odontology.
