“…34 According to a recent review, the frequency of mandibular first molars with DL roots is 14.4% and ethnicity is a predisposing factor for this anatomical variation. 35 Tu et al, 36,37 who investigated the apparent prevalence of DL roots identified with PRs and CBCT, observed prevalences of 21% and 33%, respectively. In conclusion, multiple PRs (especially the 258 mesial tube shift) or CBCT are required to assess the presence of DL roots.…”

Cone beam computed tomography (CBCT) is a relatively new method that produces three-dimensional (3D) information of the maxillofacial skeleton, including the teeth and their surrounding tissue, with a lower effective radiation dose than traditional CT scans. Specific endodontic applications for CBCTare being identified as the use of this technology becomes more common. CBCT has great potential to become a valuable tool for diagnosing and managing endodontic problems, as well as for assessing root fractures, apical periodontitis, resorptions, perforations, root canal anatomy and the nature of the alveolar bone topography around teeth. This article aims to review cone beam technology and its advantages over CT scans and conventional radiography, to illustrate current and future clinical applications in endodontic practice, and to highlight areas of further research of CBCT in endodontics. Specific case examples illustrate how treatment planning has changed with the images obtained with CBCT technology compared with only periapical radiography.

“…Conventional radiographs failed to identify at least one root canal in 4 out of 10 of the examined teeth. Tu et al (65) reported a higher prevalence of distolingual roots in the mandibular first molar teeth of a Taiwanese population when they were assessed using CBCT (33%) as compared to when conventional radiographs were used (21%). Knowledge of the presence or absence of supplemental canals and roots prior to the commencement of treatment should lead to higher detection rates in the former and more conservative access cavity preparations in the latter.…”

Cone beam computed tomography (CBCT) is a contemporary, radiological imaging system designed specifically for use on the maxillofacial skeleton. The system overcomes many of the limitations of conventional radiography by producing undistorted, three-dimensional images of the area under examination. These properties make this form of imaging particularly suitable for use in endodontics. The clinician can obtain an enhanced appreciation of the anatomy being assessed, leading to an improvement in the detection of endodontic disease and resulting in more effective treatment planning. In addition, CBCT operates with a significantly lower effective radiation dose when compared with conventional computed tomography (CT). The purpose of this paper is to review the current literature relating to the limitations and potential applications of CBCT in endodontic practice.

Aim: This article aims to provide comprehensive information related to the cone beam computed tomography (CBCT) as a diagnostic aid and its potential applications in dentistry.Background: A study was done on 10 different patients with different findings, such as Radix entomolaris, calcifications, vertical root fracture, internal resorption, cystic lesion, perforation, radicular cyst, preparation for endo surgery. These all findings could not be diagnosed by two-dimensional (2D) imaging which were diagnosed with the help of CBCT.Review results: Cone beam computed tomography is a revolutionary and innovative procedure that has changed the paradigms in the management of various endodontic conditions. Cone beam computed tomography offers speed and versatility to the practitioner and patient alike. Within few minutes of acquiring the scan, the dentist may fully explore the patient's three-dimensional (3D) image. The image can then be rotated, color-contrasted, and slices can be isolated and further analyzed. With its accurate and high-quality 3D representations, this technology offers tremendous improvements in diagnostic capabilities, eliminating surprises and minimizing the need for exploratory surgery. Conclusion:Cone beam computed tomography is an invaluable endodontic tool for use before, during, and after treatment CBCT scanning drives diagnostic accuracy, which positively impacts clinical decisions, increases speed of treatment, and improves productivity and patient outcomes. In short, it has provided the greatest advancement in digital imaging over the past decade.Clinical significance: When used for preoperative assessment, CBCT imaging provides highly detailed information on the entire tooth structure, including the location and number of canals, pulp chamber size and degree of calcification, curvature of root morphology, tooth and root fractures, inflammatory lesions and defects.
