Techniques for estimation of biological age are constantly evolving and are finding daily application in the forensic radiology field in cases concerning the estimation of the chronological age of a corpse in order to reconstruct the biological profile, or of a living subject, for example in cases of immigration of people without identity papers from a civil registry. The deposition of teeth secondary dentine and consequent decrease of pulp chamber in size are well known as aging phenomena, and they have been applied to the forensic context by the development of age estimation procedures, such as Kvaal-Solheim and Cameriere methods. The present study takes into consideration canines pulp chamber volume related to the entire teeth volume, with the aim of proposing new regression formulae for age estimation using 91 cone beam computerized scans and a freeware open-source software, in order to permit affordable reproducibility of volumes calculation.
生物年龄估计技术不断发展，并且在法医放射学领域每天都有应用，例如在涉及估计尸体实际年龄以重建生物特征的案件中，或者在涉及无身份证件的移民人员身份登记的活体案件中。牙齿继发性牙本质的沉积以及随之而来的牙髓腔尺寸减小是众所周知的衰老现象，并且通过开发年龄估计程序，如Kvaal-Solheim法和Cameriere法，已将其应用于法医领域。本研究考虑了犬齿牙髓腔体积与整个牙齿体积的关系，目的是使用91例锥束计算机断层扫描和一款免费开源软件提出新的年龄估计回归公式，以便实现体积计算的可负担得起的重复性。
