“…The initial material of study consisted of the demographic data (sex and age) and CBCT images of 400 patients who presented to the Department of Dentomaxillofacial Radiology, Faculty of Dentistry, Gazi University, between November 2014 and January 2015. The inclusion and exclusion criteria of the study were determined and modified in accordance with previous studies (6,20,(22)(23)(24). The inclusion criteria were: 1) no trauma and surgery history of the head, 2) CBCT images are good quality and free of artifacts, 3) facescanned CBCT images (field of view: 200 × 170 cm).…”

The aim of this study was to perform morphometric analysis of the foramen magnum (FM) using cone-beam computed tomography (CBCT). Materials and methods:This study included CBCT images of 190 individuals (88 males and 102 females). The sagittal and transverse diameters and circumference of the FM were measured. The shape of FM was classified as round, hexagonal, oval, egg-shaped, tetragonal, pentagonal, irregular A, and irregular B. The data were statistically analyzed with chi-square and t-tests to assess the level of significance for sex and age. Results:The means of its sagittal and transverse diameters and also circumference were higher in males than in females. Statistically significant differences were found between males and females for all variables (P < 0.05). No statistically significant difference (P > 0.05) was found between age groups for all variables. The round type was the most common, in 21.6% of the patients. Conclusion:CBCT images can provide valuable information regarding FM and the measurements of its sagittal and transvers diameters and also its circumference may be reliably used for sexual dimorphism in anthropometric analysis and forensic medicine.

This pilot study examines the applicability of osteometric models for addressing commingled remains, which were originally developed for dry specimens, on 3-Dimensional bony elements in relation to a modern cadaveric population. A total of 70 bony elements (humeri, radii, ulnae, femora, tibiae and fibulae) were segmented and virtually reconstructed from cadaveric whole-body CT scans. Linear measurements were taken (using MeshLab v.2016.12) of the 3-Dimensional elements and osteometric models for sorting applied to them (Byrd and Adams, 2003). This study showed that on the selected specimens the quality of the surface of the reconstructed specimens compromised the efficacy of the models, and consequently the reliability of the results.

“…After the metric and statistic analysis he concluded that the posterior floor of the skull's base is the most dimorphic. Foramen magnum's maximum width, occipital base's maximum width and the maximum distance between oval foraminae show a high degree of correlation with sex determination [30].…”

Sex estimation remains one of the most important steps in a forensic anthropology context, especially when dealing with deteriorated or fragmented skeletal remains. In this respect, the need for the permanent actualisation of study database, as well of the skeletal remains is obvious. Therefore, besides classical skeletal collections an important amount of data can be obtained from computed imaging of the skeletal system, namely CT scans. The CT scans have the advantage of being virtually unlimited in number, not having any interference with secular trends, individuals being of known age and sex as well as increase in accessibility and applicability of data, for subsequent statistical and complex analysis (for instance, geometric morphometric). In the following review, we have gathered and compared some of the most significant studies in the field of physical and forensic anthropology focusing on sexual dimorphism on the skull, both on skeletal collections and CT scans. The results of the studies were similar in terms of sexing accuracy, thus allowing us to conclude that using CT scans in forensic anthropology is a viable and sometimes better option than skeletal collections, in term of data acquisition.
