Abstract

Background: Dental age estimation methods are one of the most advocated and widely accepted approaches in forensic anthropology. Aim: This is an analytical study to assess pulp/tooth area ratio of 2 maxillary and 2 mandibular monoradicular teeth and to correlate pulp/tooth area ratio with chronological age. Methodology: The study was performed on a sample of 480 Radiovisiographs (RVGs) of subjects having the age range from 15-54 years. Two radiographic measurements were done on each radiograph with the help of imaging software Adobe Photoshop, CS6. One is pulp area (PA) and another one is tooth area (TA). The ratio of pulp/tooth area (PA/TA) was calculated and tabulated in Microsoft excel sheet. Data was analyzed using statistical software. Findings: One way ANOVA was done to compare mean PA/TA ratio amongst all the selected teeth. The inter-group comparison of mean PA/TA ratio was done using the Post-hoc bonferroni test. Significant negative correlation of age with PA/TA ratio was reported for the over-all sample. The mean PA/TA was significantly more among maxillary 2nd premolar in comparison to maxillary canine. Conclusion: Present study is an attempt to correlate the chronological age with pulp/tooth area ratio using monoradicular teeth only. The study can be further carried out using monoradicular as well as multiradicular teeth on a larger sample size.
