摘要

年龄估计是人类身份鉴定的重要法医学资源。在牙齿年龄估计的不同方法中,牙根透明度(RDT)被认为是一个可靠的参数,也是人类成人遗骸死亡时实足年龄的指标。本研究的目的是使用Bang和Ramm方法估计个体的年龄,并通过评估RDT的长度和百分比长度得出适合秘鲁人口年龄估计的新公式。材料和方法:样本包括248颗牙齿,来自124名年龄在30至70岁之间的死者。从切片和拍照的牙齿中数字测量RDT长度。通过线性和二次回归推导秘鲁公式,并将新公式应用于另一组样本(n=30)。结果:数据显示了显著的相关性(p结论:结果表明,使用秘鲁公式从RDT长度的百分比得出的年龄估计已被证明比使用Bang和Ramm方法的估计更准确。因此,它可用于估计秘鲁人的年龄,因为它是最准确的方法,并提供更多可接受的估计数。

Accuracy of age estimation using root dentin translucency in Peruvian adults. A pilot study.

Introduction: Age estimation is an important forensic resource in human identification. Amongst the different methods of dental age estimation, root dentin transparency (RDT) is considered a reliable parameter, as well as an indicator of chronological age at time of death in human adult remains. The aim of this study was to estimate the age of individuals using the Bang and Ramm method and to derive a new formula suitable for age estimation in the Peruvian population by assessing the length and percentage length of RDT.

Materials and methods: The sample consisted of 248 teeth collected from 124 deceased individuals, between the ages of 30 and 70 years. RDT length was digitally measured from sectioned and photographed teeth. Linear and quadratic regressions were made to derive Peruvian formulae and the new formulae were applied to another group of samples (n=30).

Results: Data showed a significant correlation (p<0.01) between chronological age and translucency length (Pearson´s correlation=0.775) and percentage length (Pearson´s correlation=0.778). Linear and quadratic regressions for obtaining Peruvian formulae showed that quadratic equations expressed greater determination coefficients. Comparisons between estimated age using Peruvian formulae showed that dental age from percentage of length of RDT a higher percentage of estimates with errors <± 05 and <± 10 years. The accuracy of the new Peruvian formula using the percentage of length of RDT (MAE=7.83) can be considered acceptable.

Conclusion: As shown in the results, age estimation using the Peruvian formula derived from the percentage of length of RDT has proven to be more accurate than estimates using the Bang and Ramm method. Thus, it could be used in age estimation for Peruvian individuals, as it is the most accurate methods and provides a larger number of acceptable estimates.
