Abstract :

Introduction:– Age estimation of an individual is important in forensic science. Many dental age estimation has been reported erlier. The volume of dental pulp cavity decreases with increasing age due to deposition of secondary dentin. Hence, pulp cavity volume changes relative to volume of tooth could be useful for dental age estimation. Aim and objective:– To estimate the dental age by pulp/tooth volume ratio and to correlate the dental age with the chronological age. Materials and methods:– CBCT images with known chronological age between 20 to 50 years. Pulp/tooth volume were measured by third party software and ratio was calculated to correlate with chronological age. Result:– The estimated mean dental age is 30.08 and the chronological mean age is 30.29 with standard deviation of 1.79 and 9.45 respectively and statistically no significant difference between mean chronological age and mean estimated age. Conclusion:– Dental age estimation by pulp/tooth volume ratio through CBCT tooth images is reliable in this study.
