OBJECTIVES The aim of the present study was to compare the accuracy of intraoral digital periapical radiography and cone beam computed tomography in the detection of periapical radiolucencies in endodontically treated teeth. MATERIAL AND METHODS Radiographic images (cone beam computed tomography [CBCT] scans and digital periapical radiography [PR] images) from 60 patients, achieved from Septe...
AIM To compare in an ex vivo model the ability of digital intraoral radiography and cone beam computed tomography (CBCT) to detect simulated external inflammatory root resorption lesions, and to investigate the effect of altering the degree of rotation of the CBCT scanners X-ray source and imaging detector on the ability to detect the same lesions. METHODOLOGY Small and large simulated extern...
The determination of the success of endodontic treatment has been often discussed based on outcome obtained by periapical radiography. The aim of this study was to verify the influence of intracanal post on apical periodontitis detected by cone-beam computed tomography (CBCT). A consecutive sample of 1020 images (periapical radiographs and CBCT scans) taken from 619 patients (245 men; mean age,...
There is little material in the literature that compares biological width measurements in periapical and bite-wings radiographs with clinical measurements. The purpose of this study was to compare measurements of biological width taken by three different methods which are frequently used for planning periodontal surgery - periapical radiograph, bite-wing radiograph and transperiodontal probing ...
introduction: the height of the alveolar bone, is normally maintained by equilibrium between bone formation and bone resorption, but in periodontal disease more destruction or lack of bone formation will reduce the alveolar bone height. however the radiography is important in diagnosis, treatment plan and detection of quality and quantity of the alveolar bone although the type of radiography is...
Introduction: Extraoral periapical radiography (EOPAR) is a technique where the film is placed extraorally overlying the tooth of interest and the X-ray beam is directed from the opposite side of the face. This technique was first proposed by Newman and Friedman (2003) and later modified by Chia-Hui Chen et al (2007) to assist certain patient populations who are unable to tolerate intraoral fil...
AIM To test the ability of periapical radiography (PA) and cone-beam computed tomography (CBCT) to determine the presence/absence of periapical lesions and examine the reliability of volumetric measurements of periapical lesions on CBCT scans. METHODOLOGY After tooth extractions in human mandibles, bone defects were cut at the base of extraction sockets to mimic periapical bone lesions. The t...
OBJECTIVES The diagnosis of root fractures by conventional radiographs is still difficult because of limitations of 2D images. Cone-beam volumetric tomography improves the diagnosis capacity in dentistry, such as increased radiation dose to the patient and presence of artifacts on the image. STUDY DESIGN This study compared the images obtained on conventional periapical radiographs and 3D sca...
