Such documentation at a scene is usually carried out by specially trained personnel using various 3D imaging devices and methods, such as terrestrial laser scanners. Unfortunately, this causes the implementation of 3D documentation at the scenes to be expensive and not readily accessible. In 2020, Apple introduced a light detection and ranging (LiDAR) sensor into their high-end mobile devices. In 2022, Recon-3D, an iOS application (app), was launched.

The remains of a late medieval (14<sup>th</sup>-15<sup>th</sup> century AD) adult male were excavated in 2017 from St Albans Monks’ Graveyard, Hertfordshire, United Kingdom. Upon visual inspection the skeleton exhibited widespread changes suggestive of Paget's disease which prompted the radiographic investigation.

Characteristic medical conditions such as Paget's disease aid identification by excluding unaffected persons, as the pathology exhibits a higher prevalence among British white males of advanced age. This example, although archaeological in origin, illustrates how data available from human skeletal remains can be leveraged through radiographic imaging to glean biographical information which might otherwise be unavailable. In the presence of fragmentary skeletal remains, and the absence of DNA profiling, pathologies with characteristic radiographic appearances could be of forensic significance.</p></div><div><h3>Conclusion</h3><p>This example demonstrates the radiographic appearances of Paget's disease on fragmentary skeletal remains which may aid victim identification efforts.

As common components of dental practice, intraoral radiographs represent an important source of antemortem (AM) data. Interpretation of these radiographs, however, may vary between forensic odontologists. The aim of this study was to investigate experts’ opinions on the interpretation of dental identifiers from intraoral radiographs. A web-based survey was distributed to international forensic odontologists. The survey included simulated cases of human identification and questions related to the use of intraoral radiographs in dental identification. Each case required the visual radiographic comparison of one AM and one postmortem (PM) intraoral radiograph. Further questions were related to the importance of different parameters that can be examined through intraoral radiographs, such as morphological, therapeutic, and pathological features; while final questions were asked about the methods used for comparative dental analysis. The survey was answered by 57 forensic odontologists across the world. The simulated case that involved therapeutic features (dental restorations) was positively identified by 56 participants (98%), while the case without therapeutic identifiers was identified only by 14 participants (24%). Almost half (54%) of the participants mentioned therapeutic features as the best (when available) for comparative human identification, followed by morphological features. The use of comparative methods for radiographic analysis was mentioned by 18 participants (32%). Intraoral radiographs enabled the analysis of dental and non-dental features – that can be therapeutic, morphological, and pathological. Specifically, therapeutic features allow a more straightforward comparison, while morphological comparisons require detailed visualization, and knowledge of anatomic structures and their variations.</p></div>","PeriodicalId":40763,"journal":{"name":"Forensic Imaging","volume":"32 ","pages":"Article 200531"},"PeriodicalIF":1.1,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49717741","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
