Abstract

Accurate dental matching is essential for forensic identification, particularly in challenging cases involving dentitions with no dental work, incomplete dentitions or damaged remains. This study evaluates similarity scoring schemes for 3D dental data using three datasets: full jaws versus single teeth (DATA-A), and two collections of heat-traumatized teeth (DATA-B and DATA-C). The similarity scores are assessed for their ability to quantify tooth curvature (dis)similarity and distinguish matching from mismatching dental comparisons. The results demonstrate the effectiveness of the methods in handling dental fragmentation (ROC-AUC_DATA-A = 0.899 (95 % CI 0.840–0.948) and heat trauma (ROC-AUC _DATA-B = 0.996 (95 % CI 0.98–1.00); ROC-AUC _DATA-C = 0.993 (95 % CI 0.980–1.00), and that they offer a robust tool for forensic applications.

烧焦或破碎，但可比性：量化牙齿，颌骨和热暴露之间的牙齿表面差异

准确的牙齿匹配对于法医鉴定至关重要，特别是在涉及没有牙齿工作的牙齿，不完整的牙齿或损坏的遗骸的具有挑战性的案件中。本研究使用三个数据集评估三维牙齿数据的相似性评分方案：全颌与单牙（data - a），以及两个热损伤牙齿（data - b和data - c）。相似性评分是评估他们量化牙齿曲率（非）相似性和区分匹配与不匹配牙齿比较的能力。结果表明，该方法治疗牙裂(ROC-AUC - data - a = 0.899（95 % CI 0.840-0.948）和热伤(ROC-AUC - DATA-B = 0.996（95 % CI 0.98-1.00）的疗效显著；ROC-AUC DATA-C = 0.993(95 % CI 0.980-1.00)，它们为法医应用程序提供了一个强大的工具。
