A comparison of the 'Raido Visio Graphy' dental imaging system (RVG), which is direct digital intraoral radiography based on a charge-coupled device, and a conventional intraoral radiography by high-speed silver halide film is reported. The results were as follows : 1. The RVG system did not require film processing in a dark room, and could produce an intraoral radiographic image immediately after exposure. 2. The RVG system could create images at a lower radiation dose, approximately 1/5 that of conventional intraoral radiography. 3. The resolving power of the RVG system was 4.6 line pairs/mm compared 17 line pairs/mm for intraoral film. Consequently, it would not suitable for some clinical applications where the fine details of small structure, such as bone trabeculae, are required. 4. However, the RVG system would be suitable for applications where radiographic images were required instantly in endodontics, exodontia and implant procedures.
