The Moldovan Medical Journal, 2021
Background: Cone-beam computed tomographic (CBCT) imaging is a valuable tool in dental practice. It is widely used in endodontic treatment for the root canal morphology examination. Therefore, the purpose of this study was to use CBCT to calculate the volume of the pulp chamber at different tooth groups. Material and methods: This study conforms to protocols approved and in accordance with the ethics committee’s requirements, informed consent was obtained from each patient. Morphologic measurements of 120 maxillary and 120 mandibular molars (from 40 patients, aged 18–45 years) were included in this study. CBCT images were taken using a Kodak 9500 (Dental Systems, Carestream Health) operated at 90 kVp with a voxel size of 300 mm and a field of view of 90-50 mm. All scans were taken following the manufacturer’s recommendation protocol. According to the examination requirements, C-shaped roots, single-rooted molars, crowned teeth, and teeth with caries and/or restorations violating the...
Cone Beam Computed Tomography: A New Boon and a Ray of Hope to the Endodontist—A Series of Cases
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.
Cone Beam Computed Tomography Imaging in Clinical Endodontics – Literature Review
Dental and Medical Problems, 2013
Cone beam computed tomography (CBCT) is widely used in dentistry due to low radiation, high-quality digital reconstruction of three-dimensional image, the elimination of the overlapping of structures which lie along the same axis, the possibility of obtaining real shaped images and enabling accurate measurements of the examined anatomical structures. Three-dimensional imaging of the structures of the stomatognathic system is most commonly implemented in endodontics, implantology and periodontics. The CBCT technique is used in endodontics primarily to detect anatomical abnormalities, visualise the root canal system, disclose additional canals, detect perforations and vertical root fractures, diagnose periapical lesions caused by inflammation of the pulp, identify and locate root resorption, clarify the reasons for the lack of healing of endodontically treated teeth. An important advantage of CBCT over conventional radiography is the fact that CBCT enables an exact visualisation of th...

Background: Dimension and location of pulp chamber are important during access cavity preparation. It allows clinician in instruments selection, orientation and depth of cutting during the process. Analysis of these has been done in preoperative intraoral periapical radiograph that gives two-dimensional image. The radiograph has been blamed now and then for the inaccurate results and iatrogenic damage occurred due to the inaccurate results. Cone-Beam Computed Tomography (CBCT) provides three-dimensional images and is taken as standard. Hence the aim of the study is to compare intra-oral periapical (IOPA) radiograph and CBCT to determine the landmarks for accurate results Methods: 50 intact two-rooted maxillary first premolars were collected and numbered. Periapical radiograph Images and CBCT images of these 50 teeth were taken and divided as; Group I: 50 IOPAR and Group II: 50 CBCT images. Landmarks marking and measurement was done using tracing paper and x-ray viewer for IOPA im...

This study revisited three oral radiology centers (ORC) and screened the main clinical indications that justified the request for cone-beam computed tomography (CBCT) examination in Endodontics. The databases of three ORCs were searched for requests of CBCT exams taken for Endodontic purposes over the last two years. The extracted data consisted of the total number of CBCT exams, the clinical indication in the endodontic field that justified the CBCT exam, the outcome of each exam (from the report of Oral Radiologists), and demographic data of the patients. From the total CBCT exams (n = 4,583), nearly 13% (n = 611) were taken for Endodontic purposes. Most of the clinical indications were related to root fractures (65%) and periapical lesions/disease (24.1%). Radiologists’ reports hypothesized more often toward periapical lesion/disease (70.5%), root fracture (51.4%) and accidents/complications (25.2%). Some clinical indications significantly varied based on age. In particular, post...
Endodontic applications of cone beam computed tomography: case series and literature review
2015
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 CBCT are 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 wi...
CBCT ANALYSIS OF PULP CHAMBER THICKNESS AND MORPHOLOGY IN PRIMARY MOLARS: AN OBSERVATIONAL STUDY
International Journal of Advanced Research, 2024
Objective: To evaluate the thickness of pulp chamber and morphologic characteristics in order to plan the treatment ofdeciduous molars using cone beam computed tomography. Material and Methods: Cross-Sectional study is done with CBCT images of primary teeth of children. Evaluation of Pulp chamber thickness and morphology of each maxillary right primary second molar was done through CBCT. Data were analyzed and sent for statistical analysis. Results: Total 50 teeth i.e., right maxillary primary second molars of children age group 4-10 years were analyzed. Male shows the horizontal and vertical Mean (SD) values 4.5 (0.76) and 1.7(0.58) respectively greater than females. Mesial and Distal pulp horns were also greater in height for males with Mean (SD) 3.1(0.51) and 2.5(0.52) respectively. Conclusion:General variations might be involved however, when preparing a course of treatment for a childit is important to take note of gender differences in the mesiobuccal pulp horn. Even small restorations have a significant effect on pulp size. Probably it becomes exposed when the cavity is being prepared.
Evidence-Based Endodontics
Cone beam computed tomography (CBCT) has become a common diagnostic method in endodontics. However, the current literature provides insufficient information about different aspects that are related to the use of CBCT, such as: the efficacy of CBCT to support the practitioner's clinical decision making and to affect treatment outcomes; about the required training of the practitioner so he can efficiently examine the entire region that appears in the CBCT scan and diagnose abnormalities or possible pathologies; and on the long-term health risks associated with the use of CBCT in endodontics. In addition, CBCT has the strong potential to be used for accurate diagnosis of complete and uneventful healing. In this thematic series, we call for manuscripts that discuss aspects of the use of CBCT in endodontics.
