Dental radiographs constitute 25% of all exposures made in the UK and therefore in terms of radiation protection the population risk is not insignificant. Paragraph 11 of The Core of Knowledge in the Schedule to the Protection of persons undergoing medical examination or treatment (POPUMET) regulations specifies the importance of using existing radiological information, whether films or reports, about a patient. The Guidance Notes recommends that in order to reduce unnecessary radiographic examinations, there should be ready availability of previous radiographs. Access to previous radiographs is also commended by the National Radiological Practice Board (NRPB) and the Royal College of Radiologists (PCR) in their report on Patient Dose Reduction in Diagnostic Radiology. In addition to dose limitation, patient care is improved.
