During the past two decades, digital radiography has supplanted screen-film radiography in many radiology departments. Today, manufacturers provide a variety of digital imaging solutions based on various detector and readout technologies. Digital detectors allow implementation of a fully digital picture archiving and communication system, in which images are stored digitally and are available a...
Background and Aim: Clinical and radiographic diagnoses of dental root fractures have always been difficult and require high accuracy in dental care and treatment. The aim of this study was to compare the diagnostic accuracy of intraoral digital radiography (PSP) and CBCT in the detection of horizontal and vertical root fractures (HRF and VRF). Materials and Methods: For this experimental stud...
In vitro Comparison of Conventional Film and Direct Digital Radiography in Proximal Caries Detection
Introduction: Various systems for intraoral digital radiography have been available as an alternative to film–based radiography. In consideration of several advantages of digital radiography such as less patient absorbed dose, manipulation of image quality and elimination of processing, it has been extensively used in different fields of dentistry in recent years. The purpose of this study wa...

This article on digital radiography image processing and display is the second of two articles written as part of an intersociety effort to establish image quality standards for digital and computed radiography. The topic of the other paper is digital radiography image acquisition. The articles were developed collaboratively by the ACR, the American Association of Physicists in Medicine, and th...
OBJECTIVE To determine the film-retake rates and causes in digital radiography comparison to conventional X-rays method. STUDY DESIGN Comparative study. PLACE AND DURATION OF STUDY Radiology Department, Aga Khan University Hospital, Karachi, from January 2004 to December 2006. PATIENTS AND METHODS X-rays of different body parts, conducted during the year 2004, with conventional radiograph...
Belma Muhamedagic, Lejla Muhamedagic Faculty of Medicine, University of Sarajevo, Bosnia and Herzegovina ography-RVG, Trophy Radiologie, Croissy Beaubourg, France [now Trophy, A Kodak Company, Rochester, N.Y.]). RVG is modern diagnostic method based on use of digital roentgen. Principle is use of so called CCD chip in RVG sensor (Figure 1) that put in patient’s mouth (3). The first dental digit...
conclusions the designed software was able to detect a significant number of dentin caries and acceptable measuring of the depth of carious lesions in enamel and dentin. however, the software had limited ability in detecting enamel lesions. background radiographs, adjunct to clinical examination are always valuable complementary methods for dental caries detection. recently, progressing in digi...
introdouction:the study aimed to compare the accuracy of proximal caries detection by dental practitioners using two different systems, direct digital system and conventional films, under routine environmental conditions. materials and methods: eleven extracted human posterior teeth were mounted on wax frames and were exposed using the direct digital system and conventional films. seventy-four ...
conclusions according to the results of this study, the accuracy of the file length in improved digital images showed no significant difference in comparison with the actual file length. materials and methods using an analytical-diagnostic method, an access cavity was prepared in 36 mandibular and maxillary premolar teeth. a file # 15 was inserted into the canal of each tooth until the tip of t...
