Introduction: The appropriateness of dental care is intimately related to the accuracy of diagnosis. Dental radiographic images constitute a vital diagnostic tool in dental practice. While the risks of ionizing radiation to patients and operators are not fully understood, statistical risk estimations must be weighed against specific benefits. Risk analysis is usually based on the biological effects seen in laboratory studies and at higher doses. These data are then extrapolated, and inferences are made about the hazards to human beings exposed to x-radiation. It is accepted that diagnostic levels of x-radiation can potentially cause harmful effects. This concern alone demands that professional judgment always be used when handling radiation.
Purpose: The purpose of this document is to establish guidelines that will govern the use of ionizing radiation within the College of Dentistry. The intent is for patients to receive minimal radiation necessary for diagnosis and treatment. The decision to expose any patient to radiation for diagnostic purposes should consider that any exposure to ionizing radiation is potentially harmful. The policy statements in this document apply to all patients treated or evaluated within the College of Dentistry. The only exceptions are consenting patients participating in research protocols approved by the Radiation Safety Committee and the Office of Research Administration / Institutional Review Board of the University of Oklahoma Health Sciences Center (OUHSC).
The ionizing radiation guidelines in this section are reviewed annually and revised, as necessary. They incorporate those procedures and protocols that improve the risk-benefit ratio by maximizing the diagnostic yield from radiography and minimizing exposure to unnecessary radiation. Staff, faculty, and students are expected to be thoroughly familiar with these guidelines and to apply them in every instance of radiation use.
