In forensic scenarios, such as armed conflicts or mass disasters, the oral cavity can be a valuable source of identification information relevant to legal issues. In many European Union countries, it is mandatory to register dental records for identification purposes. A pilot and quasi-experimental study was performed. The study aims to analyze two methodologies, photography and wireless intraoral (IO) laser scanner, in the scope of the orofacial record in forensic pathology, highlighting their impact on human identification. The IO scanner i700 (Medit, Lusobionic, Portugal) and Canon 5D-Full Frame equipment were used to record the individual status, living patients ( = 5), and forensic cases ( = 5). IO and extraoral anatomical structures were recorded following six parameters: time, mineralized and soft detail, communication, extra devices, and distortion. The statistical analysis was performed in accordance with a scoring system and Mann-Whitney ( < 0.05) analysis. The photography method recorded extraoral data for all samples (score range between 15 and 23). The time elapsed to complete an IO scan in forensic cases was shorter than with photography, without requiring additional sources of light or mirror devices. Living patients and corpses identified statistically significant differences. It can be concluded that laser scanners are a valuable tool in the field of forensic pathology and can be used to record and analyze anatomic-morphological data for identification purposes accurately.
Human identification engages in orofacial details records.Photographic and laser scans record intraoral and extraoral anatomic structures.Forensic cases assessed by intraoral scanner technology are accurate and less time-consuming, optimizing the orofacial data for identification.
在诸如武装冲突或大规模灾难等法医场景中，口腔可能是与法律问题相关的重要身份识别信息来源。在许多欧盟国家，为了身份识别目的，强制要求登记牙科记录。开展了一项试点和准实验性研究。该研究旨在分析摄影和无线口腔内（IO）激光扫描仪这两种方法在法医病理学口腔面部记录范围内的应用，突出它们对身份识别的影响。使用IO扫描仪i700（Medit，葡萄牙卢索生物公司）和佳能5D全画幅设备记录个体状况、活体患者（n = 5）和法医案例（n = 5）。按照六个参数记录IO和口腔外解剖结构：时间、矿化和软组织细节、通信、额外设备以及失真情况。根据评分系统和曼 - 惠特尼分析（p < 0.05）进行统计分析。摄影方法记录了所有样本的口腔外数据（分数范围在15至23之间）。法医案例中完成一次IO扫描所花费的时间比摄影短，且无需额外的光源或反光设备。活体患者和尸体之间存在统计学上的显著差异。可以得出结论，激光扫描仪是法医病理学领域的一种有价值工具，可用于准确记录和分析解剖形态数据以进行身份识别。
身份识别涉及口腔面部细节记录。
摄影和激光扫描记录口腔内和口腔外解剖结构。
通过口腔内扫描仪技术评估的法医案例准确且耗时更少，优化了用于身份识别的口腔面部数据。
