Introduction: Radiopacity is a necessary property for luting cements . The aim of this study was to investigate the radiopacity of some luting dental cements used in prosthetic dentistry. Methods: Five disclike samples of each material (6 x 1 mm) were prepared from panavia F2.0(Pa), Chioce2 (Ch.2), Glass ionomer GC (GI GC), zinc phosphate Hoffmann’s (ZP hof), zinc polycarboxylate Hoffm...

background : retakes of intra oral radiographs happen frequently in dental practice although radiographic courses train dental students in consecutive semesters. to reduce the patient exposure as much as possible it is mandatory to reduce the number of retakes both in radiology clinics and educational centers. materials and methods : 3188 periapical radiographs taken by bisect-angle technique w...

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...

Dental radiography is considered to be a diagnostic tool for a proper treatment planning of the disorders of oral cavity like periodontal diseases, diff erent oral pathologies, and dental caries. In pediatric dentistry, radiography is a part of daily practice because of its unusual and unique role. As the child is brought in the clinic for the 1st time, radiology has been proven to be an accept...

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...

BACKGROUND AND OBJECTIVE Clinicians have difficulty assessing and monitoring early occlusal caries. Traditional clinical exam and radiographs are unable to detect the subtle alterations in enamel indicative of de- or re-mineralization, particularly under dental sealants. Although clinicians have used laser fluorescence (LF) to address this gap, this modality has demonstrated weak correlation wi...

Dental Radiographs have a valuable aid in the diagnosis of periodontal diseases and the evaluation of treatment effects. Computer-based image acquisition and processing techniques will now further increase the importance of radiography in periodontal diagnosis. Digital Subtraction Radiography (DSR) requires a pair of images with identical gray-level distribution and projection geometry is neede...
