[A general roentgenographic procedure with high reliability and minimum radiation exposure].

Needs for exposure procedures in dental radiography with improved reliability and radiation hygiene, that can be applied with a minimum of time, have been documented. This publication presents a systematic approach to reliable dental radiography using beam guiding instruments which may meet such requirements. It can provide accurate radiographs in endodontic, periodontic and general practice and is adaptable to more time consuming special purpose radiography, including "serial identical" exposures and exposures of handicapped or anaesthetized patients.
