Digital radiography in dentistry

ABSTRACT

Since its inception in 1895 by Roentgen, the field of diagnostic sciences has undergone constant development. In 1984 Dr. Frances Mouyens introduced digital radiography in dentistry. 10-20% dental practitioners in North America use digital radiography, and the numbers are on an increase. Digital radiography uses intraoral sensor replacing silver halide film. X-rays fall on the sensor and an image is formed on a computer screen instantaneously, avoiding time-consuming chemical processing of conventional radiography. Moreover, there is a 90% reduction in radiation dosage. A digital image can be manipulated in various ways. This article reviews the basic concept of digital radiography. This is a review article
