Report No. 177 – Radiation Protection in Dentistry and Oral & Maxillofacial Imaging (2019) (Supersedes Report No. 145)

Report No. 177 – Radiation Protection in Dentistry and Oral & Maxillofacial Imaging (2019) (Supersedes Report No. 145)

No exposure to x rays can be considered completely free of risk, so the use of radiation by dentists and their assistants implies a responsibility to ensure appropriate protection. This Report provides radiation protection guidance for the use of x rays in dental practice, including the use of cone-beam computed tomography, digital-imaging devices, and handheld x-ray systems. The aim of this Report is to provide a practical radiation protection guide for dentists and their assistants. Information is presented in a clear and comprehensive format focusing on dental radiological practices.

SC 4-5: Radiation Protection in Dentistry Supplement: Cone Beam Computed Tomography, Digital Imaging, and Handheld Dental Imaging
Description This report is urgently needed as there are no formal guidelines on the safe and effective use of these modalities in the United States. In addition, every dental practitioner acts as an independent radiologist. CBCT units are generally installed as plug-and-play devices and they are not perceived by most in dentistry as computed tomography […]
SC 4-7: Evaluating and Communicating Radiation Risks for Studies Involving Human Subjects: Guidance for Researchers and Reviewing Bodies
Members only Description Tens of thousands of individuals participate annually in clinical trials and research studies involving human subjects. Many of these studies expose the subjects to ionizing radiation, often through imaging examinations. Currently, there is limited and varied guidance available to assist researchers and institutional review boards in preparing protocols that involve radiation exposure […]
SC 4-13: Patient Shielding in Medical Imaging
Description Patient shielding has been accepted as best practice in radiology for over half a century. On January 12, 2021, NCRP issued Statement No. 13 advising against the routine use of in-field gonadal shielding during radiographic imaging of the abdomen and pelvis. Reasons included extensive scientific evidence that gonadal shielding does not contribute significantly to […]
