Although sizeable three-dimensional (3D) scanning modalities exist in osteology and anthropology, developing new advanced methods and techniques involving 3D scanning for real-life forensic applications require that the accessibility, practicality, and, more importantly, accuracy of the methods be taken into consideration. To this end, this study aimed to assess the reliability of 3D surface scanning-based topographical and shape analysis comparison to gold standard micro-focus X-ray computed tomography (micro-XCT) reconstructions for estimating population affinity.</p><p>Forty-four adult crania were collected from the Pretoria Bone Collection (PBC), University of Pretoria, South Africa. Two sets of 3D reconstructions were acquired from each cranium, namely micro-XCT scans and 3D surface scans. Three-dimensional reconstructions and landmark datasets were acquired from both scanning modalities and compared using reproducibility testing, geometric discrepancies, and shape analysis.</p><p>The minimal geometric discrepancies observed between the reconstructions suggest that both modalities will provide similar shape landmarks datasets and can be used without compromising the accuracy of the analyses at term. The statistical findings showed similar population affinity-related mid-facial shape variations analyzed across both modalities using geometric morphometric methods (GMM).</p><p>Incorporating multiple 3D scanning modalities and advanced GMM into the existing biological profile estimation will allow South African forensic anthropologists to analyze shape-related skeletal variation in a more accurate and repeatable way and provide an efficient biological profile in forensic cases.</p></div>","PeriodicalId":40763,"journal":{"name":"Forensic Imaging","volume":"34 ","pages":"Article 200550"},"PeriodicalIF":1.1,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49717936","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}

Ribs were photographed before and after maceration using blue light (Crime-Lite 2, 450nm), coupled with an orange camera filter. Thermogravimetric analysis was used to quantify collagen content, and a bespoke computer program: The Osteo-Fluorescence Calculator (OFC) was used to quantify bone fluorescence.</p></div><div><h3>Results</h3><p>Ribs macerated in hot water exhibited homogenous fluorescence and produced a 5.5% average increase in fluorescence levels (n=10, s.d.=9.36, p=0.012) alongside a 11.2% loss in collagen content (n=10, s.d.=0.09, p=0.023). Biological washing powder was destructive to bone surfaces and produced an average collagen loss of 22.9% (n=10, s.d.=0.05, p= <0.001), while fluorescence was augmented (54.49%) and inconsistent (n=10, s.d.=27.46, p=0.180). Enzymatic maceration produced an average increase in fluorescence of 23.2% (n=10, s.d.=23.72, p=0.180), with a mostly consistent appearance except for some dark patches, and experienced a 19.5% loss in collagen content (n=10, s.d.=0.09, p=0.001).</p></div><div><h3>Conclusions</h3><p>Hot water maceration produced fluorescence results comparable to fresh bone with little impact on bone collagen and provides a suitable preparation technique for osseous ALS examination. Biological washing powder was destructive to bone collagen and produced exaggerated, inconsistent fluorescence and therefore should be avoided. Enzymatic maceration was the fastest method but requires an optimised formulation.</p></div>","PeriodicalId":40763,"journal":{"name":"Forensic Imaging","volume":"34 ","pages":"Article 200556"},"PeriodicalIF":1.1,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49717904","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}
