Resumo
Forensic anthropology (FA) aims to study the human body to aid justice. The
human skull is recognized as a structure that houses a series of characteristics
subject to individual variability which can occur due to the biological sex of the
individuals, genetic action of ancestry, or age. Volumetric examinations allow the
observer to assess morphology in a differentiated manner, and volume is one of the
ways to represent this topography. However, there is a gap in studies in this field, as
various structures can aid in forensic analysis, especially in the context of searching
for missing persons. To evaluate the individualizing capacity of the zygomatic bone in
studying sexual dimorphism and human identification. The pilot study included 36
anonymous cone-beam computed tomography (CBCT), divided between 18 male
and 18 female. The DICOM files were imported into Blender with OrthogOnBlender
addon to reconstruct the bone tissues and export it into .stl files. In the Freeform
software, using a haptic device to precisely select the zygomatic bone at its borders
with the temporal, sphenoid, frontal, and maxillary bones. Tests showed normality in
distribution. T-tests demonstrated a statistically significant difference (p=<0.05) in the
variables Volume (p=0.033) and Height (z) (p=0.004). The volumetric analysis of the
zygomatic bone proves to be a promising tool for sex estimation in human
identification services.
