A digital radiograph is basically an all digital version of an x-ray. As your topic implies, they are more commonly becoming used in dental settings to get x-ray views of teeth and gums. Traditionally, the x-rays are emitted from a moveable device and are captured on special photographic film which then has to be photochemically processed before it can be viewed. With digital radiography, the x-rays are captured by a digital sensor which then immediately translates the information into a digital image seen on a computer screen. The benefits are that smaller doses of radiation can be used and the digital images can be stored and viewed in numerous locations without mailing paper. The drawback is the extra cost.
