X‐rays were discovered in 1895 by Wilhelm Roentgen. Digital radiology has overtaken conventional screen‐film radiography since it was introduced in the mid‐1980s.[1] Digital imaging uses sensor of solid‐state, and information is presented and stored as an image using a computer. The dawn of the digital era in dental radiography came in 1987 with the first digital radiography system called radio...

INTRODUCTION The recent literature data points out a rising application of digital radiography--radiovisiography (RVG)--in dental clinical practice. OBJECTIVE The aim of this study was to apply and compare RVG with the conventional radiographic technique (CRDG) in terms of accuracy in linear measurement in dentistry. METHODS Measurements were done on the mandibular dogs teeth considering in...

Nowadays, bone mass estimation, through imaging methods, is widely used in metabolic diseases diagnosis and treatment. One of these methods is called "optical densitometry" which estimates bone density by measuring the intensity of the transmitted light on different parts of a radiographic image. Digital radiography systems act similarly by determining grey levels of the image. The aim of this ...

INTRODUCTION The aim of this study was to determine in anterior teeth, bicuspids, and molars (1) the accuracy of 3 different electronic apex locators (EALs) in detecting the apical foramen and (2) the accuracy of digital radiography in determining the working length (WL), compared with visible control under a microscope. METHODS By using radiovideography (RVG), we measured the lengths of 120 ...
