[Evaluation of the new radiovisiography system].

The latest version of the Radiovisiography-system was evaluated in comparison to its predecessor and a high speed periapical film (Agfa Dentus M4). Both RVG-systems proved to have the same sensitivity and are capable of displaying a similar contrast range. Nevertheless additional functions of the new system allow a much better visualisation of the radiographed structure. Compared with Dentus M4 periapical films the RVG-System provides less sensitivity but a wider range of contrast.
