Abstract

Age estimation is an important issue in both anthropological and forensic fields. One of the most difficult problems facing forensic medicine is that of estimating the age of living subjects, as in cases where individuals are undergoing criminal proceedings, or are requesting asylum. Biological age estimation based on dental records was previously conducted using conventional orthopantography (OPG) radiographs. However, the reliability of this technique is within ±6 months. The aim of this study is to investigate the reliability of using pulp/tooth volume ratio (PTR) to estimate chronological age. The study sample consists of 30 patients scanned with the I-CAT Cone Beam Computed Tomography system. Selected teeth in each dataset will be manually segmented using AMIRA software to assess the volume of the pulp and dentine to analyze PTR. Linear regression analysis will be performed to assess the correlation between PTR and chronological age. The test hypothesis is that there is a positive correlation between PTR and chronological age.
