背景:这项研究的目的是评估远程工作的法医是否可以使用由操作口腔内摄像机(IOVC)的非牙科法医人员制作的视频准确地进行法医牙齿鉴定。该研究的目的是评估以这种方式进行远程法医牙齿鉴定的准确性和时间。
方法:解剖和人类识别中心(CAHID)的八具尸体,邓迪大学,英国,由法医牙科医生通过传统的牙科检查进行检查。记录他们的牙齿状况,作为本研究的死前记录。使用医学生操作的IOVC制作每个牙列的视频。由一位不参加传统牙科检查的远程第二法医牙科医生从视频中为每个牙列制作了尸检记录。然后比较了死前和死后的记录,鉴定被归类为积极建立,可能或排除。
结果:尽管在死前和死后记录之间存在一些非关键的不一致,但在所有8例病例中都取得了积极的确认。在第二种意见之前,每个研究对象85.6%的牙齿被一致地绘制。在第二种意见之后,一致性百分比增加到97.2%。每个视频的平均持续时间约为4.13分钟,第一次尝试解释和绘制死后牙科检查的平均时间为11.63分钟。从视频中绘制图表所需的时间比传统牙科检查所需的时间更长。
结论:这项初步研究支持进行远程牙科识别的可行性。这种新颖的“远程牙科病毒病”方法可能是传统验尸牙科检查的可行替代方法,在由于地理原因难以获得法医牙科服务或受到限制的情况下,后勤,安全,和/或政治原因。
BACKGROUND: The aim of this study was to evaluate whether a forensic odontologist working remotely could accurately undertake forensic dental identifications using videos produced by non-dental forensic staff operating an intra-oral video camera (IOVC). The study\'s aims were to assess the accuracy and time taken to perform remote forensic dental identifications in this manner.
METHODS: Eight cadavers from the Centre for Anatomy and Human Identification (CAHID), University of Dundee, UK, were examined by a forensic odontologist via a traditional dental examination. Their dental condition was recorded to serve as ante-mortem records for this study. Videos of each dentition were produced using an IOVC operated by a medical student. Post-mortem records were produced for each dentition from the videos by a remote second forensic odontologist who was not present at the traditional dental examination. The ante-mortem and post-mortem records were then compared, and identification was classified as positively established, possible or excluded.
RESULTS: Established identifications were positively made in all eight cases although there were some non-critical inconsistencies between ante-mortem and post-mortem records. Before the second opinion, 85.6% of the teeth per study subject were charted consistently. After the second opinion, the percentage of consistency increased to 97.2%. Each video on average was about 4.13 minutes in duration and the average time taken to interpret and chart the post-mortem dental examination at the first attempt was 11.63 minutes. The time taken to chart from the videos was greater than is typical of a traditional dental examination.
CONCLUSIONS: This pilot study supports the feasibility of undertaking remote dental identification. This novel \"tele-dental virtopsy\" approach could be a viable alternative to a traditional post-mortem dental examination, in situations where access to forensic dental services is difficult or limited due to geographical, logistical, safety, and/or political reasons.
