“…Detectability also appears to be CBCT scanner-specific (Elsaltani et al 2016, Tiepo et al 2017. The detector sensitivity, voxel parameters, exposure parameters, speed and degree of scan rotation, and variations in image reconstruction have an impact on the accuracy of CBCT (Bechara et al 2013b, Bezerra et al 2015, Talwar et al 2016.…”

The use of cone beam computed tomography (CBCT) in the diagnosis and/or management of endodontic problems is increasing and is reflected in the exponential rise in publications on this topic in the last two decades. The aim of this paper is to: (i) Review current literature on the endodontic applications of CBCT; (ii) Based on current evidence make recommendations for the use of CBCT in Endodontics; (iii) Highlight the areas in which more research is required.

“…Although the influence of the type of radiopaque material on the detection of root fractures using CBCT images has been reported, the filling material used has been restricted to guttapercha. 3,5,6 The results of these studies consistently reveal that gutta-percha cones produce distinct streaking artifacts and beam hardening on CBCT axial slices that might simulate fracture lines, leading to false-positive results. 3,7,8 Our aim is to verify the performance of three CBCT machines in detecting VRFs in teeth filled with different endodontic sealers.…”

“…1,2 Cone beam computed tomography is a superior imaging modality that is a useful adjunct to clinical findings, thereby enabling an accurate diagnosis, 3,4 although several factors, such as voxel size, the field of view (FOV), and the presence of radiopaque materials inside the root, may cause interference in the final image. 5,6 These parameters vary among different CBCT units and different imaging protocols within the same unit.…”

Aim:To evaluate the performance of three cone beam computed tomography (CBCT) machines in detecting vertical root fractures (VRFs) in teeth filled with different sealers. Materials and methods: A total of 80 single-rooted premolars were subjected to instrumentation and restoration with gutta-percha + AH Plus sealer, gutta-percha + sealer 26, gutta-percha + fill canal, and gutta-percha without sealer as the control. Half of the samples were randomly subjected to root fracture and all the teeth were scanned by i-CAT (Imaging Sciences International, Hatfield, USA), PreXion (PreXion Inc., San Mateo, USA), and OrthoPhos XG (Sirona Dental System, Bensheim, Germany). Three examiners analyzed the images for the presence of fractures. Results: The highest accuracy was obtained with the PreXion device, with Az = 0.85, while the i-CAT device provided higher sensitivity (0.93).The specificity values observed ranged between 0.75 and 0.70. Chi-squared tests (p > 0.05) demonstrated that the sealers did not exert a significant influence on the diagnosis of VRF. Conclusion: It may be concluded that endodontic sealers do not influence the detection of VRF. The PreXion device was the most accurate, having the highest specificity value. Clinical significance: Radiopaque materials might affect the diagnosis of VRFs because they can simulate fracture lines, leading to false-positive results. Moreover, CBCT machines present different specificities that could exert some influence on that.Coronal access cavities were prepared, and the root canal treatment was done with a ProTaper Rotary System (DENTSPLY, Maillefer, Tulsa, OK, USA) up to size F3.The samples were divided into 4 groups with 20 teeth per group. The filling materials used per group were gutta-percha without a sealer, gutta-percha + AH Plus (DENTSPLY, Maillefer Tulsa, OK, USA), gutta-percha + sealer 26 (DENTSPLY, Maillefer Tulsa, OK, USA), and gutta-percha + fill canal (TechNew, Rio de Janeiro, Brazil).Teeth were wrapped in a thin layer of wax no.7 (TechNew, Rio de Janeiro, Brazil) until the region of the cervical collar. The teeth were then embedded in polyvinyl chloride (PVC) tubes containing acrylic resin.

Aim To assess observer performance in detecting endodontic complications using three different cone beam computed tomography (CBCT) units with and without the application of artefact reduction modes. Methodology The study involved 40 freshly extracted human mandibular teeth (n = 10 per group) and divided randomly into four endodontic complication groups. Group 1) Instrument fracture; Group 2) Strip perforation; Group 3) Canal underfilling; and Group 4) Canal overfilling. Images of each tooth were obtained using three different CBCT units offering artefact reduction algorithms: the ProMax 3D Max, the Pax Flex 3D and the Dentri S. Four observers evaluated the images for the presence/absence of the four simulated endodontic complications. Weighted kappa coefficients and intra‐class correlation coefficients (ICCs) were calculated to reveal the intra‐ and inter‐observer agreement for each imaging mode, respectively. Receiver operating characteristic (ROC) analysis was used to evaluate the observers’ performance. DeLong tests were used to compare the results for each image mode and observer using a significance level of α = 0.05. Results In each of the four simulated endodontic complication groups, no significant differences were observed with and without application of artefact reduction for any of the three CBCT units tested. Only two significant differences were detected, and both were between the ProMax 3D Max at low mode AR and ProMax 3D Max without AR: observer 2 in group 1 (P = 0.0001) and observer 4 in group 4 (P = 0.0256). Conclusion For each of the three CBCT units tested, application of artefact reduction for detecting endodontic complications is not recommended as a routine tool.
