Age estimation, whether for living or deceased individuals, is crucial in forensic sciences. Traditionally, the pulp-to-tooth area ratio determined from periapical radiographs has been employed as a non-invasive method for estimating age. Cone-beam computed tomography (CBCT) represents a newer technique, providing three-dimensional images of teeth in living individuals.
This study aims to estimate age using the pulp-to-tooth area ratio of four teeth (the permanent maxillary central incisor, lateral incisor, canine, and first premolar.
The study included ninety subjects ranging in age from 18 to 70 years.
This study concluded that the correlation between actual age and estimated age varied across different tooth types. There was a strong positive correlation between the maxillary right central incisor and maxillary right canine tooth, while the maxillary left canine tooth exhibited a slightly weaker but still positive correlation. This indicates that the maxillary right central incisor and maxillary right canine tooth are the most reliable for estimating age. Additionally, the study found that the linear regression results for estimating age based on the pulp-to-tooth area ratio, categorised by sex and each type of tooth, showed strong associations between age and the ratio for the maxillary left central incisor and maxillary left canine teeth in males, and for the maxillary left central incisor in females.
年龄估计，无论是针对在世者还是逝者，在法医学中都至关重要。传统上，从根尖片确定的牙髓与牙齿面积比已被用作一种非侵入性的年龄估计方法。锥形束计算机断层扫描（CBCT）是一种较新的技术，可提供活体个体牙齿的三维图像。
本研究旨在利用四颗牙齿（上颌恒中切牙、侧切牙、尖牙和第一前磨牙）的牙髓与牙齿面积比来估计年龄。
该研究纳入了90名年龄在18至70岁之间的受试者。
本研究得出结论，实际年龄与估计年龄之间的相关性因牙齿类型而异。上颌右侧中切牙与上颌右侧尖牙之间存在强正相关，而上颌左侧尖牙的相关性稍弱但仍为正相关。这表明上颌右侧中切牙和上颌右侧尖牙在估计年龄方面最可靠。此外，研究发现，根据性别和每种牙齿类型，基于牙髓与牙齿面积比估计年龄的线性回归结果显示，男性上颌左侧中切牙和上颌左侧尖牙以及女性上颌左侧中切牙的年龄与该比值之间存在强关联。
