Digital radiography: update for oral health care workers.
Digital Radiography is an imaging system that does away with the use of films. It constitutes an advance in computer technology and has made a significant impact on the field of Maxillofacial- and Dental Radiology. This paper presents an overview of the basic concepts and applications of dental digital radiography and compares it with conventional film-based imaging. In addition, it provides a thorough understanding of the direct, semi-direct and indirect dental digital imaging systems with their advantages and disadvantages. Universal acceptance of digital radiographic imaging as a diagnostic tool makes it important for oral health care workers to understand the principles thereof and to master the techniques involved in acquiring a diagnosable digital radiographic image.
