Abstract

The aim of this study is to validate the FIDBv2 online procedure for adult age-at-death estimation using root dentine translucency (RDT) and periodontal retraction (PR) of single-rooted teeth in a worldwide sample. The sample includes 4810 teeth of 2559 individuals from 16 countries of America, Europe and Asia. Bias and inaccuracy between documented (DA) and estimated ages (EA) were calculated. Pearson and Intraclass Correlation Coefficients were computed to assess the strength of agreement between pairs of data, while Kolmogorov-Smirnov Z was used to evaluate the statistical significance of the differences. The percentages of correctly estimated cases within different age ranges were obtained to find trends in the reliability of the results. Most of the biases (-4.61–1.31 years) and inaccuracies (4.81–9.72 years) are low. The dispersion of EA increases with age and almost all the DA-EA correlations are above 0.75. DA-RDT and DA-PR correlations are positive, most of the former being high (0.74–0.91), and the latter being low (0.11–0.54). The highest percentages of correct estimations are identified for the ±7.5 and ±10 years ranges, and most comparisons of bias and inaccuracy between countries are non-significant. The high correlations between DA and EA suggest that the method is robust and reliable for a global application. Mean errors are low, with the best results found in the 30–69-year-old cohort. This research supports that the method is effective and accurate for age estimation in forensic contexts worldwide, thus reaffirming it is a generalizable procedure locally and internationally.
法医国际牙科数据库(FIDBv2),用于在多种法医情况下估计成人死亡年龄:在全球范围模型中加强拉门丁标准的可操作性
本研究的目的是在全球样本中验证 FIDBv2 在线程序,该程序利用单根牙齿的牙根牙本质半透明度(RDT)和牙周回缩率(PR)估算成人死亡年龄。样本包括来自美洲、欧洲和亚洲 16 个国家 2559 人的 4810 颗牙齿。计算了记录年龄(DA)和估计年龄(EA)之间的偏差和误差。计算皮尔逊和类内相关系数以评估数据对之间的一致性强度,而 Kolmogorov-Smirnov Z 则用于评估差异的统计意义。我们获得了不同年龄范围内正确估计病例的百分比,以发现结果可靠性的趋势。大多数偏差(-4.61-1.31 岁)和误差(4.81-9.72 岁)都较低。随着年龄的增长,EA 的离散度也在增加,几乎所有的 DA-EA 相关性都在 0.75 以上。DA-RDT和DA-PR呈正相关,前者大多较高(0.74-0.91),后者较低(0.11-0.54)。±7.5岁和±10岁范围的估计正确率最高,国家间偏差和不准确性的比较大多不显著。DA和EA之间的高度相关性表明,该方法在全球应用中是稳健可靠的。平均误差较低,30-69 岁人群的结果最佳。这项研究证明,该方法在全球法医年龄估算中是有效和准确的,从而再次证明它是一种可在本地和国际上推广的程序。
