Digital radiography was used to measure the radiopacity of 18 resin cements to determine the influence of inorganic filler content on radiopacity. Four disk specimens (n=4) of each light-curing cement were digitally radiographed alongside an aluminum step wedge using an intraoral sensor (XIOS Plus, Sirona, Germany), and their mean gray value measured. Percentage of filler by weight was determin...

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...

Proximal dental caries remains a prevalent disease with only modest detection rates by current diagnostic systems. X-ray radiography represents the most common and successful means of diagnosing early dental caries lesions, however; many new systems are available without controlled validation of diagnostic efficacy. This study evaluated the caries detection of three new dental radiographic imag...

introduction: external root resorption is a clinical problem that often cannot be detected clinically. thus, radiography plays a crucial role in its diagnosis. however, optimal radiographic quality with minimal radiation exposure {2.1 [en] verify english word/phrase choice} is an important factor in selecting the appropriate radiographic technique. the aim of this study was the comparison of ac...

PURPOSE The purpose of this study was to assess radiographer familiarity and preferences with digital radiography in four teaching hospitals and thereafter make recommendations in line with the migration from screen film to digital radiography. MATERIALS AND METHODS A questionnaire was designed to collect data from either qualified or student radiographers from four teaching hospitals. From t...

PURPOSE This study evaluated the diagnostic accuracy of the reverse contrast mode in intraoral digital radiography for the detection of proximal dentinal caries, in comparison with the original digital radiographs. MATERIALS AND METHODS Eighty extracted premolars with no clinically apparent caries were selected, and digital radiographs of them were taken separately in standard conditions. Fou...

Optical coherence tomography (OCT) is a noninvasive technique providing cross-sectional images of a tooth structure. This review describes the use of OCT for detecting dental caries, tooth fractures, and interfacial gaps in intraoral restorations. OCT can be a reliable and an accurate method and a safer alternative to X-ray radiography.

BACKGROUNDS Despite the rapid development of digital dentistry, the use of digital intraoral scanners remains limited. The aim of this study was to evaluate the changes in views on intraoral scanners among dental hygienists after training. METHODS Thirty-four dental hygienists with >3 years of clinical experience participated and were divided into 2 groups : iTero and Trios groups. Participan...
