Age Estimation Using Pulp/ Tooth Volume Ratio By Cone Beam Computed Tomography
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2018, Vol 17, Issue 3
Abstract
The formation of secondary dentin leads to an age related decrease in the pulp cavity. Hence the pulp volume can be useful for age estimation using the three-dimensional processing of the radiographic images of the teeth- such as the modern Cone Beam Computed Tomography (CBCT) which allows the adoption of a non destructive, reliable and rather accurate method for dental age estimation. Aim: The aim of the present study was to develop a non-invasive, conservative, reliable, accurate and simple method of dental age estimation by mean of the analysis of the volume decrease phenomenon which affects the pulp cavity of the teeth using three-dimensional radiographic images of the CBCT. Materials and Methods: The sample of single rooted teeth wasselected from20 CBCT radiographs in North Indian subjects of any gender and age between 15 and 60 years. The images consisting of the maxillary central incisor and canine of either side were selected in DICOM file format (OnDemand 3D software version:1-0-10). The ratio of "pulp/ tooth volume" has been obtained and then correlated with the age of the subject. The results have been statistically analyzed. Results: There was a moderate correlation between chronological age and pulp/ tooth volume ratio. Conclusion: The presented method is a promising tool in the procedure for age estimation, permitted by the high technological level achieved by the currently available machines for the CBCT.
