Abstract The exposure required to obtain optimal image quality was determined using conventional intraoral x-ray film (Eastman Kodak, Rochester, NY) and the RVG-S Radio VisioGraphy-S: Trophy Radiology, Vincennes, France) CCD-based intraoral radiographic imaging system. The RVG-S permitted dose reductions of 50 to 65% for individual exposures in comparison with Ektaspeed film, and 73 to 76% when compared to Ultraspeed film. The dose dynamic for the RVG-S was 8.6 times narrower than that for conventional film. Perception of low contrast details was not significantly different between either type of x-ray film and the RVG-S.
