To assess the diagnostic accuracy of cone beam computed tomography (CBCT) in comparison with conventional radiography for vertical root fractures, 50 of 100 teeth were subjected to vertical root fracture (VRF) and then placed in dry mandibles. 3D scans were obtained for all teeth, and conventional radiographs were used as control images. All the images were assessed by 6 observers, who determin...

objectives : bone assessment is essential for diagnosis, treatment planning and prediction of prognosis of periodontal diseases. however, two-dimensional radiographic techniques have multiple limitations, mainly addressed by the introduction of three-dimensional imaging techniques such as cone beam computed tomography (cbct). this study aimed to assess the accuracy of cbct for detection of marg...

Atlantoaxial osteoarthritis (AAOA) is a unique clinical syndrome that differs from other degenerative disorders. It heterogeneous disease associated with the loss of integrity articular cartilage changes in underlying bone and cortical edges. One biggest challenges AAOA making diagnosis. In dentistry, given increasing use cone beam computed tomography (CBCT) to evaluate maxillofacial structures...

Respiratory motion causes artifacts in slow-rotating cone-beam (CB) computed tomography (CT) images acquired for example for image guidance of radiotherapy. Respiration-correlated CBCT has been proposed to correct for the respiratory motion, but the use of a subset of the CB projections to reconstruct each frame of the 4D CBCT image limits their quality, thus requiring a longer acquisition time...

INTRODUCTION The outcome predictors identified with data from periapical radiographs (PA) and cone-beam computed tomography (CBCT) scans might not be the same. This retrospective study evaluated various factors that might affect the outcome of root canal therapy. METHODS In total, 115 teeth (143 roots) with vital pulps were endodontically treated and followed up 2 years after treatment. Multi...

The digital revolution is changing the world, and dentistry is no exception. The introduction of a whole range of digital devices (intraoral, extraoral, face scanners and cone beam computed tomography (CBCT) with low dose radiation) and processing software

Cone Beam Computerized Tomography (CBCT) is an application that has taken dentistry by storm. With CBCT, imaging is accomplished by using a rotating gantry to which an x-ray source and detector are fixed. A divergent pyramidal-or cone-shaped source of x-radiation is directed through the area of interest onto an area x-ray detector. The x-ray source and detector rotate around a fixed fulcrum wit...

surgical procedure for removal of impacted teeth is a challenge for clinicians as it involves accuracy in the diagnosis and localization of the dental elements. the cone-beam computed tomography (cbct), compared to the conventional radiography, has a greater potential to provide complementary information because of its three-dimensional (3d) images, reducing the possibility of failures in surgi...

BACKGROUND This study aimed to compare the diagnostic accuracy of cone-beam computed tomography (CBCT) unit with digital intraoral radiography technique for detecting periodontal defects. METHODS The study material comprised 12 dry skulls with maxilla and mandible. Artificial defects (dehiscence, tunnel, and fenestration) were created on anterior, premolar and molar teeth separately using bur...

Cross gender-age trabecular texture analysis in cone beam computed tomography Purposes: To investigate whether multiple texture features in different regions-of-interest (ROIs) on cone beam computed tomography (CBCT) are correlated with gender-age variation of trabecular patterns. Methods: CBCT volumes from 96 subjects were used. The data set was divided into four gender-age subgroups including...
