“…In several studies on bilateral symmetry of the scapula, it was exhibited that there was no significant difference between the right and left scapula [10][11][12]14]. However, Dabbs and Moore-Jansen (2010) and Hudson et al (2016) indicated the presence of bilateral asymmetry in the right and left scapula [25,26].…”

“…Several studies have been using long bones [6,7], metatarsal [8], and vertebral bodies [9] as alternatives for sex estimation. Nevertheless, the scapula is also one of the bones that manifest sexually dimorphic features [10,11]. The reason being, that after growth response has stopped, the changes in scapula are almost insignificant in its sexuality [11].…”

“…Several studies have been conducted on the estimation of sex from scapula [10][11][12][13][14][15], where various human groups displayed different skeletal features depending on their geographical areas and genetic pattern [5,16]. These studies had used either dry skeletal collection [12][13][14] or multi-slice computed tomography (CT) for sex estimation [10,11,15,17]. Over the recent decades, multi-slice CT has been extensively used in forensic anthropology.…”

Objective: Sex estimation is one of the crucial steps for human identification, which is evident in cases of commingled, eroded, and/or missing remains. When pelvis or skull are unavailable, scapula has been used as an alternative bone for determining sex. Besides, the scapula was shown to be population-specific in several studies. Limited dry bone collections in Malaysia have led to various recommendations of virtual anthropology studies of bone in human identification. The aims of this study were to investigate the sexual dimorphism of the scapula using three-dimensional (3D) computed tomography (CT) imaging and to generate population-specific equations for sex determination in the Malaysian population. Methods:A total of 66 CT thorax images of 33 males and 33 females were taken. Morphological breadth (MB) and morphological length (ML) on bilateral scapulae were measured on 3D CT reconstructed images. Independent t-test and discriminant function analysis (DFA) were performed for analysis.Results: Results revealed that both parameters showed sexual dimorphism of scapula but displayed no difference between the right and left scapulae. DFA showed that MB and ML had high accuracy for sex estimation. The equations were highly accurate when both parameters were used in combination, followed by MB only and ML only, in that sequence. Conclusion:In brief, scapula measurements may be useful for forensic assessment of sex in the Malaysian population.

Three-dimensional convolutional neural networks (3D CNN) as a type of artificial intelligence (AI) are powerful in image processing and recognition using deep learning to perform generative and descriptive tasks. The advantage of CNN compared to its predecessors is that it automatically detects the important features without any human supervision. 3D CNN are used to extract features in three dimensions where input is a 3D volume or a sequence of 2D pictures e.g., slices in a cone-beam computer tomography scan (CBCT). The main aim of this article was to bridge interdisciplinary cooperation between forensic medical experts and deep learning engineers. With emphasis activating clinical forensic experts in the field with possibly basic knowledge of advanced artificial intelligence techniques with interest in its implementation in their efforts to advance the forensic research further. This paper introduces a novel workflow of 3D CNN analysis of full-head CBCT scans. Authors explore and present 3D CNN method for forensic research design concept in five perspectives: (1) sex determination, (2) biological age estimation, (3) 3D cephalometric landmark annotation, (4) growth vectors prediction, (5) facial soft-tissue estimation from the skull and vice versa. In conclusion, 3D CNN application can be a watershed moment in forensic medicine, leading to unprecedented improvement of forensic analysis workflows based on 3D neural networks.
