Determination of Criteria for the Age Estimation (Chronological) According to Structural Changes of Teeth and Alveolar Bone Height in Images of Cone Beam Computed Tomography in Adults

The chronological age is a key to legal medicine research. The aim of this study was to Determination of Criteria for the Age Estimation According to Structural Changes of Teeth and Alveolar Bone Height in Images of CBCT in Adults. The present cross-sectional study was derived from Cone Beam Computed Tomography(CBCT) images of spring 2016 to March 2018 in the Radiology Department of Hamadan School of Dental Medicine. The research investigated radiographic images of 265 patients referred to the School of Dental Medicine in the age range of over 20 years of both sexes with at least two molar teeth at both sides based on Gustafson’s method. The correlation between the predicted and real age in the age group of over 40 years was significant in both men and women. In the age group under 40, the male and female buccal bone height variable was the most predictor that had a significant effect in the regression model. In men, there was a significant difference between age and various erosion levels. In both groups of men and women, there was a significant difference between age and different levels of periodontal recession. There was a significant difference between age and heights of buccal bone in both men and women (P<0.05). Measurement of buccal bone level by the CBCT had the best and highest relationship with chronological age. The examination of buccal bone level is appropriate for the legal age estimation. © 2019, Indian Journal of Forensic Medicine and Toxicology. All rights reserved.
