“…The volumetric alteration is material dependent and can be expressed as over-or underestimation. 10,13,18 As in several studies, the materials used in this study demonstrated particular behavior concerning tomographic volumetric alteration, which can be explained, among other factors, by intrinsic characteristics such as physical density, atomic number of its sub compounds and composition homogeneity. 13 In accordance with previous studies, 9,10,18 amalgam showed the highest volumetric alteration rate, regardless of the protocol used, mainly due to the high atomic number of its compounds and greater density among the cylinders.…”

“…The study of the volumetric alteration artefacts is essential; understanding its expression under different conditions makes it possible to predict its behavior and better interpret CBCT images, as it is influenced by acquisition parameters, 9 CBCT unit 11 and material. 9,10,13 Zoom reconstruction stands out for the ability to reconstruct a given area of interest from previously acquired CBCT scans into new volumes with reduced FOV and voxels sizes without having to reexpose the patient to ionizing radiation and increase image. 14 A lower voxel size has been proven to be very useful for various diagnostic tasks.…”
