Radiographic examinations should be made only when the dentist has determined they are necessary for diagnostic and treatment purposes. Radiographic selection criteria have been published by the American Dental Association (ADA) to assist dentists in decision-making and justification of the prescription Once such a determination has been made, it is the responsibility of the dentist to ensure that optimal radiographic images are obtained at the lowest possible dose of radiation. Because radiographic procedures are delegated to dental hygienists and dental assistants, it is important that these radiographers have the knowledge, skill, and technical acumen to obtain optimal results. Increasingly, digital radiographic imaging is being used with two types of receptors: photostimulable phosphor plates and solid-state detectors.
