“…Furthermore, there is a lack of ancestry in these studies. There are no studies on the application of CBCT on Negroid ancestry, and there is only one study 20 on the application of CBCT in the Caucasian population. In any study, it would be useful to broaden the sample for better results.…”

“…Ruiz 16 acquired CBCT digital images with iCATVision software to locate and measure soft tissue. Lastly, De Donno 20 used the Image Tool of the ILUMA® CBCT scanner, and the soft-tissue measurements were taken as follows: first, each landmark was identified on the bone surface; then, a line was drawn perpendicular to the tangent to the landmark and extended up to the facial profile. The STT measure corresponds to the distance from the bone to the skin.…”

“…In Masoume 14 and Hwang, 19 the side of the measurements was not defined. In Hwang 18 and De Donno, 20 the measurements were taken on the right and left side. In Hwang 11 , Meundi 9 and Perlaza Ruiz, 16 CBCT scans were examined on both the right and left side in order to assess any differences, but with a discrepancy in the results.…”

When human remains are found, with no evidence of identity, facial approximation can be a useful technique to employ. The reconstruction of the ante-mortem appearance can reproduce the likely features of the face, starting from the skull, based on the overlying soft-tissue thickness. Over the years, many techniques have been developed to achieve soft-tissue thickness measurements, one of which is based on the use of cone beam computed tomography. This study aimed to review the status of this technique and to evaluate heterogeneity among studies undertaken in this field, with particular regard to determination of landmarks, sex and body mass index.

“…Using MPR is common and has been used to measure the wax thickness in this study. De Donno et al, [4] used the MPR to measure 12 easily recognizable bone landmarks, corresponding to well-defined anatomic structures, with an acceptable approximation of the underlying bone surface. Bulut et al, [8] used MPR and sagittal images along each tooth plane to measure the diameter and depth of the external root resorptions cavities.…”

“…CBCT has become a leading technology as an imaging modality in the medical diagnostic radiology with several advantages such as (i) the possibility to acquire images with subjects in the upright position; (ii) providing the radiologists with high-resolution images while using less ionizing radiation for the patient compared to multislice CT, (iii) clinically acceptable, and (iv) high precision regarding all the linear, angular and volumetric measurements of hard tissue with an accuracy of 1.0 mm [1,4,5] .…”

Objective: The aim of this study is to assess the effect of different CBCT voxel sizes on the soft tissue thickness measurements in a variety of maxillary and mandibular regions. Methods: Two thicknesses (less than 2.0 mm and more than 2.0 mm) of pink baseplate wax as simulated soft tissue were overlaid on a maxilla and mandible of a dry human skull. The thicknesses were measured with a digital caliper as the physical measurements. The skull was scanned using CBCT with four different voxel sizes (0.20, 0.25, 0.30 and 0.4 mm). CBCT measurements were compared to the physical measurements. Intraclass Correlation Coefficient was used to assess both intra-and inter-observer reliability. Significance was considered to be 5% (P ≤ 0.05). Results: Results showed a significant difference between the CBCT measurements using the 0.3 and 0.4 mm voxel sizes scans compared to the physical measurements when wax thickness was less than 2.0 mm. On the other hand, no significant difference was found for the CBCT measurements using the four voxel sizes when thickness was greater than 2.0 mm. Conclusions: CBCT scans with voxel sizes of 0.3 mm and 0.4 mm provide accurate simulated soft tissue measurements when the thickness is more than 2.0 mm. However, when greater visualization of details are required, scans with lower voxel sizes is required. Therefore, in a clinical situation, it is of great importance to customize the resolution protocol according to the accuracy needed.
