INTRODUCTION This in vitro study compared cone-beam computed tomography (CBCT) exam with different voxel sizes with digital periapical radiography in the detection of vertical root fractures in teeth with and without intracanal metallic posts. METHODS Eighteen single-rooted human teeth were endodontically treated, prepared for cast metal posts, and(More)
The aim of this study was to evaluate the influence of changes in maxillomandibular positioning during cone beam computed tomography (CBCT) imaging on the planning of dental implants. Ten skulls were marked bilaterally with metal spheres in four regions: incisors, canine, premolars, and molars. CBCT scans were obtained in seven positions: standard position(More)
INTRODUCTION This study compared the detection of fractured instruments in root canals with and without filling by periapical radiographs from 3 digital systems and cone-beam computed tomographic (CBCT) images with different resolutions. METHODS Thirty-one human molars (80 canals) were used. Root canals were divided into the following groups: the control(More)
PURPOSE To evaluate the presence of the anterior extension (AE) of the mandibular canal and to measure the bone height (BH) at different points along the extension. MATERIALS AND METHODS Cone-beam computed tomography examinations of 108 patients were bilaterally evaluated regarding the presence of the AE, and linear measurements of the AE and BH were(More)
AIM To evaluate the influence of cone-beam computed tomography (CBCT) filters on diagnosis of simulated endodontic complications. METHODOLOGY Sixteen human teeth, in three mandibles, were submitted to the following simulated endodontic complications: (G1) fractured file, (G2) perforations in the canal walls, (G3) deviated cast post, and (G4) external root(More)
The temporomandibular joint (TMJ) is a complex anatomic structure and a variety of morphological changes can occur on its osseous surfaces. This study aimed to evaluate the influence of cone-beam computed tomography filters for detection of surface osseous changes of the TMJ to verify the best conditions for evaluating this area. Images of 100 TMJs were(More)
