“…The LV micro‐CT scanning system has been used in research for oral surgery (Beetge et al, 2018; Stan et al, 2019; Theye et al, 2018), biomedical (Grace et al, 2022; Kusins et al, 2019; Wearne et al, 2022) and medical research (Hutchinson et al, 2016; Kramer et al, 2019; Main et al, 2021; Smit et al, 2020; Tan et al, 2022; Welsh et al, 2020), paleontology (Clement et al, 2021), and forensic investigations (Alsop et al, 2022, Braun et al, 2022, Nikolova et al, 2019, Rutty et al, 2012). The non‐invasive nature of this type of micro‐CT scanner, as well as its technical capabilities, suggests that it could be of great value for the investigation of rare, delicate, and valuable archaeological human remains.…”

Archaeological investigation of the dentoalveolar complex in situ within a human skull requires detailed measurements using non-invasive techniques. Standard macroscopic and radiographic methods have limitations but large volume micro-computed tomography (LV micro-CT) scanning has the potential to acquire data at high resolution in microns. In this study, archaeological specimens are analyzed using three-dimensional data visualization software from LV micro-CT scans with the aims of (1) determining whether LV micro-CT can act as a single technique to provide detailed analysis of the dentoalveolar complex and (2) how findings from the LV micro-CT technique compare with standard methods. These aims are explored by measuring a range of human skull specimens from a rare archaeological sample requiring non-invasive methods, for multiple dental and alveolar bone health categories. The LV micro-CT technique was the only method to provide a full range of detailed measurements across all categories studied. A combination of macroscopic and radiographic techniques covered a number of categories, but the use of multiple methods was more time consuming, did not provide the same level of accuracy, and did not include all measurements. There were high levels of reproducibility for intra-operator scoring and good inter-operator agreement from four operators with one operator whose results were outliers. As a further investigation of the potential of the LV micro-CT technique, an additional individual, a fragile, fragmented skull of an infant was studied. This investigation confirms the value of LV micro-CT scanning as a non-invasive, accurate, single technique for the extensive analysis of the dentoalveolar complex within archaeological skulls, which also allows the relationship of different tissues to be studied in situ.

“…Large Volume Micro-CT scanning has previously been used for clinical research (3)(4)(5)(6), forensic investigations (7,8), and some research of archaeological bone samples including the skeleton of King Richard III of England (9)(10)(11)(12)(13). However, none of these cases have focused on the dentoalveolar complex in-situ in the skull.…”

Background Archaeological investigations of human skeletal material require non-destructive techniques. Large Volume Micro-Computed Tomography (LV Micro-CT) scanning systems allow acquisition of data from complete skulls. This study aims to determine 1) whether LV Micro-CT scanning can as a single technique provide adequate data for the analysis of the dentoalveolar complex, 2) how its outputs of dental and alveolar bone analyses compare to those of macroscopic and radiographic methods, and 3) how it compares with Small Volume Micro-Computed Tomography (SV Micro-CT), for analysis of individual teeth? Material and Methods: Five archaeological human skulls were investigated. These represented both sexes and a broad age range. Large Volume Micro-CT, Macroscopic and Radiographic methods and SV Micro-CT scanning were used. Statistical analysis of intra and inter-operator reproducibility using five observers was undertaken. Results: Large Volume Micro-CT as a stand-alone technique provided results across the full range of dentoalveolar complex categories measured. By combining traditional techniques similar results were obtained. There were high levels of reproducibility for intra-operator scoring and good inter-operator agreement from 4 operators with 1 operator whose results were outliers. Discussion: The LV Micro-CT was the only technique to singularly provide a full range of measurements. A combination of the other techniques covered a similar range of categories, but the use of multiple methods was more time consuming. For some specific measurements, SV Micro-CT provided more detailed information. Conclusion: This first study confirms the value of LV Micro-CT scanning for the analysis of the dentoalveolar complex of archaeological samples. Findings demonstrate the advantage of LV Micro-CT, which provided a comprehensive range of data as a stand-alone technique rather than combing modalities to achieve the same result. The SV Micro-CT provided higher resolution analysis for loose individual teeth due to the small size of the specimens but could not study the alveolar bone.
