title: Beam-guiding instruments for simplified dental radiography, with a training device.
abstract: Needs for exposure procedures in dental radiography with improved reliability and radiation hygiene, which can be applied with a minimum expenditure of time, have been documented. This article presents dental instruments designed for use in recently published general purpose x-ray procedures which may meet such requirements. They can provide accurate radiographs in endodontic, periodontic, and general practice and are adaptable to more time-consuming special-purpose procedures, including "serial identical" exposures and exposures of handicapped or anesthetized patients.
