Dental radiographic examinations are valuable tools that aid in the diagnosis and treatment of oral diseases.  A dental patient’s risk of radiation exposure is miniscule but nonetheless real, and dental professionals need to be current on the latest research and theories on radiation safety and protection. This basic-level course reviews the biologic effects of radiation, the terms associated with radiation measurement, and the potential sources of radiation exposure for both patients and dental professionals.  This course prepares dentists, dental hygienists, and dental assistants to accurately respond to patient questions and concerns regarding radiation safety in dentistry.
