“…CBCT supplies the clinician with an accurate detailed diagnostic data which directly influence the clinical decisions and facilitate selection of accurate treatment plan which grants a good prognosis. 3 Thus, CBCT is widely used in various dental disciplines including implantology, endodontics, periodontology, maxillofacial surgery and orthodontics. 4 CBCT is a very useful tool in endodontic field as it determines root morphology, number of roots, canals and accessory canals, as well as establishing working length and angulations of roots and canals.…”

Cone beam computed tomography (CBCT) affords high-quality image with a relatively low radiation doses and low costs. It is considered as a valuable tool in endodontic field as it determines root morphology, number of roots, canals and accessory canals. The aim of the present study was to evaluate the permanent mandibular anterior teeth canal morphology in Egyptian subpopulation. Materials and Methods:A total of 100 patients were enrolled in this study and were assigned in two groups (50 females and 50 males). In each group centrals, laterals and canines of both sides were examined (100 centrals, 100 laterals and 100 canines). CBCT Images were obtained using J Morita CBCT unit and canals were categorized into the five types of Vertucci's classification. The observer evaluated the images twice with one-week interval between assessments.Results: Type I Vertucci configuration was the most prevalent configuration in our sample and the incidence of this type was slightly higher in female than male samples. Furthermore, type III and V Vertucci configuration were slightly more in males than females. Conclusion:In the present study it was concluded that the root and root canal morphology of Egyptian subpopulation was, in general, comparable to that of other populations and that the incidence of canal variations might occur as a result of ethnicity more than gender.

“…However, use of conventional radiography for this purpose results in false negative results in 51.9% and false positive results in 15.3% of cases (6). The CBCT technology aids the diagnosis of endodontic pathosis and analysis of resorption defects (7). Defects smaller than 0.6mm in diameter and less than 0.3mm in depth are not detectable on conventional periapical radiographs; this results in under-diagnosis and progression of root resorption (8, 9).…”

BackgroundSelecting a voxel size that yields minimal radiation dose with no significant compromise of the diagnostic accuracy of cone beam computed tomography (CBCT) is particularly important.ObjectivesThis study aimed to assess the effect of voxel size on detection accuracy of simulated external root resorption defects using NewTom CBCT system.Materials and MethodsIn this diagnostic study, the roots of 90 extracted human central incisors were hypothetically divided into cervical, middle, and apical thirds. Variable-size defects were prepared in the buccal and lingual surfaces of the roots and CBCT scans were obtained with four different voxel sizes (150, 200, 250, and 300). Presence or absence of defects on CBCT scans was determined by three radiologists and the results were compared with the gold standard (actual size and depth of defects). Sensitivity and specificity values were calculated and reported for different groups.ResultsIn the lingual surfaces, the highest specificity and sensitivity belonged to 300µm voxel size (92.9%), and 200 and 250µm voxel sizes (both 97.4%) in the cervical third, respectively. In the middle third, the highest specificity and sensitivity belonged to 250 and 200µm voxel sizes (84.6% and 100%, respectively). In the apical third, the highest specificity and sensitivity belonged to 300 µm voxel size (100% and 97.9%, respectively). In the buccal surfaces, the highest specificity and sensitivity belonged to 150 (75.0%), 300 and 250 µm voxel sizes (100%) and the minimum values belonged to 200 µm voxel size (60% and 97.3%) in the cervical third. In the apical third, the highest specificity and sensitivity were noted in 300 µm voxel size (100% and 97.6%, respectively) and the minimum values were seen in 200 and 150 µm voxel sizes (93.8%, 90.5%, respectively). In the middle third, 300, 250 and 200 µm voxel sizes yielded the highest specificity (88.9%), while 150 µm voxel size yielded the highest sensitivity (98.8%).ConclusionConsidering the similar diagnostic efficacy of all voxel sizes, 300 µm voxel size can be used with adequate efficacy for detection of external root resorption defects with minimal patient radiation dose and the shortest scanning time.

“…Most of the studies evaluating the application of CBCT in clinical practice have been carried out in smaller samples or by applying one of the two clinical guidelines. [2][3][4]7 Mota et al, 7 used a sample of 53 patients; their study presents the greatest methodological similarity to the present research. In their study, the dental groups examined by CBCT most frequently corresponded to upper posterior (49%), followed by upper anterior (22%).…”

“…Moreover, until now, most of the research evaluating CBCT in clinical practice has focused on case reports or case series with small study samples. [2][3][4] In 2012 the European Commission on Radiation Protection published clinical guidelines for the use of CBCT in dental practice. This document was created by the SEDENTEXCT project, a multidisciplinary group consisting of specialists from various areas such as dentistry, radiology, and radiological industry technicians.…”

The aim of this study was to evaluate the clinical utility of Cone Beam Computed Tomography (CBCT) in cases of medium and high endodontic complexity. The relevance of CBCT to define treatment was evaluated through the Wittenberg questionnaire and the variation in treatment plans after CBCT exam analysis. The sample (n=40) was chosen for convenience over a period of 4 months. It considered the current recommendations to request CBCT exams before performing root canal treatments. Data collection was carried out through a survey applied to the treating clinicians, after examining the information obtained by the CBCT system. Data were analyzed with the Stata version 13 software, and the Chi-square test was used for inferential analysis. A 95% confidence interval was considered. The most frequent dental groups corresponded to upper posterior and upper anterior teeth (47.5% and 30.0%); the cases were equally distributed according to complexity (50% and 50%). The main reason for requesting CBCT exams corresponded to complex anatomy and/or atypical canal system (37.5%). The use of CBCT increased confidence in the initial treatment chosen by clinicians in 50% of cases according to the Wittenberg questionnaire, and a 45% variation in treatment plans was observed. There was no statistical relationship between complexity and the variables studied. CBCT contributed greatly to the therapeutic management of cases regardless of their complexity.
