“…These results demonstrate that CBCT is a reliable and effective diagnostic tool for detecting bone defects. The present findings exhibit a high degree of agreement with the outcomes of all previous in vivo investigations [ 3 , 14 ]. Notably, the present study is one of the rare studies that has assessed and juxtaposed CBCT measurements of periodontal defects with actual surgical measurements in vivo.…”

Introduction: Assessing bone condition holds significant value in the diagnosis, treatment planning, and prognosing the periodontal disease; its importance is undeniable. The main aim of the present study was to evaluate the accuracy of alveolar bone measurements due to periodontal disease using cone-beam computed tomography (CBCT), by comparing with surgical measurements, considered as the gold standard. Materials and methods: A prospective cross-sectional study included a sample of 40 individuals diagnosed with chronic periodontitis who required periodontal surgery. A total of 202 sites were assessed for vertical and horizontal bone loss in the anterior (76 sites) and posterior (126 sites) teeth. Bone loss was measured using CBCT and a UNC 15 periodontal probe during the surgical intervention, and then compared. The statistical analysis involved employing a Student's t-test to compare measurements. Unpaired t-tests and correlation analyses were conducted using Pearson's correlation coefficient test. To establish statistical significance, a threshold of p<0.05 was considered appropriate. Results: The statistical analysis carried out on the mean values of CBCT and direct surgical measurements for vertical bone loss demonstrated a significant difference (p<0.01). However, the values obtained for horizontal bone loss did not display statistical significance. A strong correlation of 0.94-0.99 existed between surgical and CBCT measurements. A statistically significant distinction was observed between the two methods in measuring bone loss at the distal and palatal sites of the anterior teeth. Conclusion: Both CBCT and direct surgical measurement exhibit comparable accuracy potential in assessing alveolar bone loss. CBCT provides an accessibility advantage by enhancing visual access to challenging sites during surgical interventions, including palatal and distal areas of the teeth.

“…The equipment used in this research has 14 bits (2 14 = 16,384 different gray tones) in which the real number of significant densities is limited by imprecision in image acquisition, and it is generally more difficult to specify the correct threshold value to separate the bone from soft tissue and background in CBCT than in conventional CT due to inherent inconsistencies in the histogram. Studies described in the literature (Damstra et al, 2010;Pitale et al, 2020), in which surface models were processed by a volumetric renderization program related that the smallest detectable difference in the CBCT measurements were minimal, confirming the exactness of the CBCT measuring process. Barbero & Ureta (2011), and Alsharbaty et al (2019) affirmed that the dimensional error of CT mainly occurs due to the selection of minimum gray scale parameters that separate the noise right from the beginning of the contours of the part, and the easiest segmentation algorithm to use is the use of a global threshold value.…”

This study compared the acquisition protocols of the Conical Beam Computed Tomography (CBCT) system, to assess the influence on image accuracy by different voxel sizes and the presence of soft tissue. Tomographic acquisition was performed in a fresh (F) and dry (D) pork jaw with voxel sizes of 0.4, 0.3 and 0.25 mm. The gold standard was obtained by scanning dry jaws covered with barium sulfate with a voxel size of 0.25 mm. The images were treated in the MIMICS® program, and noise areas were removed manually, using a fixed threshold for the purpose of generating 3D printing windows. Each window was virtually overlaid with the gold standard using the MeshLab software, obtaining absolute error values between the meshes, generating a map of discrepancies. Significant differences were found between windows D 0.30 vs. F 0.30, D 0.30 vs. F 0.25, D 0.30 vs. D 0.25, D 0.30 vs. F 0.40, F 0.30 vs. D 0.25, F 0.25 vs. D 0.25, F 0.25 vs. D 0.40, D 0.25 vs. F 0.40, D 0.25 vs. D 0.40 and F 0.40 vs. D 0.40, (p <0.05). It was observed that the dry jaw windows showed a lower mean and standard deviation when compared to the fresh jaw windows. The 0.25 mm voxel protocol showed the most accurate result and the presence of soft tissues influenced the accuracy of the image when some protocols were compared statistically.

“…The use of orthopantomography is justified due to its lower price, even though CBCT is a far more advanced technique with higher accuracy and precision during analysis and making a diagnosis [33]. Acar et al have described all advantages and disadvantages of CBCT's use in dental implantology in their paper, and have especially pointed out CBCT's ability to perform multiplanar reconstructions (Table 1) [34].…”

As radiology rapidly and continuously develops, dental radiological devices are becoming integral to dental practice. CBCT enables a precise three-dimensional image of the orofacial region. The wider use of CBCT devices is further encouraged by the flaws of two-dimensional radiological methods, especially concerning dental implantology. This paper aims to describe the advantages and disadvantages of using CBCT devices in planning and placing dental implants. It offers an insight into artifacts and radiation doses and their influence on the quality of the resulting image. The generation of multiplanar slices of the area of interest, the possibility of 3D reconstruction, the reduction of the magnification error, and the radiation dose are some of the important advantages of the CBCT device. A Limited FOV and volume of the screening, a low range of contrasts, measuring of bone density and shades of grayscale, as well as possible artifacts of movement are some of its disadvantages. Not only did the CBCT device find a purpose in the processes of planning and placement of dental implants, but also in postoperative assessments of healing and possible complications. CBCT balances the price and radiation dose and the quality of clinical information. It is used in oral surgery, orthodontics, periodontology, and endodontics. Due to its precision and quality, the CBCT device is the foundation of dental implantology.
