“…Also, the use of a small FOV may improve the spatial resolution of CBCT in certain brand devices. 41 Notably, all clinical studies were found to use the periodontal probe as a tool for clinical intrasurgical measurement except for the study by Banodkar et al, 39 who employed an endodontic reamer and digital Vernier calliper for taking this measurement. Compared to the periodontal probe, this novel approach was found to be more accurate in obtaining clinical measurements with an accuracy of up to 0.2mm.…”

Objective: This study aims to assess the accuracy of the linear measurements of intrabony and/or furcation defect quantified by cone beam computed tomography (CBCT). Material and Methods: A systematic search of the literature was conducted by two authors independently from the PubMed, Scopus, and EBSCO for full articles published in journals between January 2003 and March 2017. Eligible studies were assessed for quality and heterogeneity using the QUADAS-2 tool. A meta-analysis was performed to identify the accuracy of CBCT in the measurement of intrabony defects. The effect size was estimated and reported as the standardised mean difference (SMD). Results: A total of 105 titles and abstracts were screened. Of those, 11 articles met the inclusion criteria for the systematic review while only four were selected for metaanalysis. The overall effects of standardized mean difference and 95% CI was-0.03 [95% CI-0.67 to 0.60] with a x 2 statistic of 0.49 with 3 degrees of freedom (p>0.05), I 2 = 0.01%. Conclusion: CBCT is highly accurate and reproducible regarding linear measurements for assessing intrabony defects with a weighted standardized mean difference of 0.03mm. More randomised controlled trials are required to assess the accuracy of CBCT in assessing patients with periodontal defects.

“…With different hardware components, like X-ray sources and detectors, used by the different manufacturers for their systems further variations in image quality are introduced 4 . The local tomography at the selected scan settings makes the data interpretation therefore often difficult 5 . For this reason, it was decided to perform a tomography study of the same human donor head with multiple CBCT scanners, each time scanned with a variety of machine settings.…”

An entire human head obtained at autopsy was micro-CT scanned in a nano/micro-CT scanner in a 6-hour long session. Despite the size of the head, it could still be scanned with a pixel size of 70 µm. The aim of this study was to obtain an optimal quality 3D data-set to be used as baseline control in a larger study comparing the image quality of various cone beam CT systems currently used in dentistry. The image quality of the micro-CT scans was indeed better than the ones of the clinical imaging modalities, both with regard to noise and streak artifacts due to metal dental implants. Bony features in the jaws, like the trabecular architecture and the thin wall of the alveolar bone were clearly visible. Therefore, the 3D micro-CT data-set can be used as the gold standard for linear, angular, and volumetric measurements of anatomical features in and around the oral cavity when comparing clinical imaging modalities.

Image quality evaluation of small FOV and large FOV CBCT devices for oral and maxillofacial radiology

Abstract: For limited oral and maxillofacial volume imaging (diameter < 50 mm), the polyvalent small FOV CBCT (2D and three-dimensional imaging) system used in this study could reach performances similar to those of the large FOV CBCT.
