Radiographic imaging is essential in diagnosis, treatment planning and follow-up in endodontics. The applications of cone beam computed tomography (CBCT) in endodontics has been widely reported in the literature.It provides high-quality, accurate threedimensional (3D) representations of the osseous elements of the maxillofacial skeleton. The purpose of this article is to discuss the features, a...
Background: In prostate radiotherapy, changes in the volume of the bladder and rectum can influence dose delivery. In this study, cone-beam computerised tomography (CBCT) imaging was used to assess volumetric, and corresponding radiation dosimetric changes, for the bladder and rectum in patients with prostate cancer treated using VMAT. Materials and Methods: Treatment planning computed tomograp...
this report describes the non-surgical treatment of an invaginated maxillary lateral incisor with two fused roots. the mesial root had a c-shaped canal, while the distal one had a type iii dens invagination. cone-beam computed tomography (cbct) was used to help with the diagnosis and treatment decision making. clinical and radiographic follow-up revealed satisfactory periapical repair and absen...
With the advances in the field of imaging sciences, new methods have been developed in dental radiology. These include digital radiography, density analyzing methods, cone beam computed tomography (CBCT), magnetic resonance imaging, ultrasound, and nuclear imaging techniques, which provide high-resolution detailed images of oral structures. The current review aims to critically elaborate the us...
The purpose of this study was to verify the angular measurement values conventional Lateral Cephalometric Radiographs (LCRs) and Cone-Beam Computed Tomography (CBCT) Mid- Sagittal Plane (MSP) projections when using same cephalometric analysis method.
The objective of this study was to assess and compare the organ and effective doses in the knee area resulting from different commercially available multislice computed tomography devices (MSCT), one cone beam computed tomography device (CBCT) and one conventional X-ray radiography device using MOSFET dosemeters and an anthropomorphic RANDO knee phantom. Measurements of the MSCT devices resulte...
introduction: an overlooked but important part of successful root canal treatment is a straight-line access (sla). the purpose of this in vitro study was to compare the efficacy of introfile and prerace rotary instruments with gates glidden (gg) drills in gaining sla by cone-beam computed tomography (cbct). methods and materials: a total of forty five extracted mandibular first molars were sele...
Purpose: Kilovoltage cone-beam computed tomography (CBCT) has been developed to provide accurate soft-tissue and bony setup information. We evaluated clinical CBCT setup data and compared CBCT measurements with electronic portal imaging device (EPID) images. Material and Methods: The setup error for CBCT scans at the treatment unit relative to the planning CT was measured for 62 patients (524 s...
Today, we are in a world of innovations, and there are various diagnostics aids that help to take a decision regarding treatment in a well-planned way. Cone beam computed tomography (CBCT) has been a vital tool for imaging diagnostic tool in orthodontics. This article reviews case reports during orthodontic treatment and importance of CBCT during the treatment evaluation.
