This systematic review evaluates the diagnostic accuracy of radiographic methods employed to indicate presence/absence and changes over time of periapical bone lesions. Also investigated were the leads radiographic images may give about the nature of the process and the condition of the pulp in nonendodontically treated teeth. Electronic literature search included the databases PubMed, Embase a...

The objective of this study was to evaluate the marginal and internal fit of zirconia copings obtained with different digital scanning methods. A human mandibular first molar was set in a typodont with its adjacent and antagonist teeth and prepared for an all-ceramic crown. Digital impressions were made using an intraoral scanner (3Shape). Polyvinyl siloxane impressions and Type IV gypsum model...

An overview of working with digital X–ray sensor equipment digital intraoral sensors (See Figure 1, opposite page) and this has given me the opportunity to develop and hone a vast array of tips and techniques to help make capturing images with digital intraoral sensors more comfortable and more consistent than ever before. Before we get into specific sensor placement tips, here are some general...

Dental radiography is an essential component in the delivery of high-quality dental care for dogs and cats. During the 1980s veterinarians began taking radiographs of teeth using standard radiographic units; however, these units made patient positioning difficult and often resulted in suboptimal films. In the 1990s dental radiographic units became a more common part of the veterinary dental dia...

This article on digital radiography image acquisition is the first 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 processing and display. The articles were developed collaboratively by the ACR, the American Association of Physicists in Medicine, and the...

Digital imaging is becoming widely used in diagnostic radiology, and digital subtraction angiography (DSA) is now generally accepted [1-3]. Several studies have evaluated digital imaging using a computed radiography system for chest examinations [4-10] and for excretory urography [11] . This prospective study uses receiver operating curve analysis [12 , 13] to compare the diagnostic accuracy of...

introduction proper cleaning and shaping of the root canal system is one of the most important aspects of endodontic therapy. to estimate the canal length before instrumentation in endodontic treatment, traditionally, conventional radiographic techniques and, recently, direct digital radiography (ddr) are applied. the application of computer technology in radiography has allowed less exposure t...
