Understanding the forms of radiation and the risks and effects associated with dental radiography is essential to providing the highest quality of care to the dental patient. Appropriate for all dental professionals, this basic-level course outlines radiation risk, the effects of exposure to ionizing radiation, and the measurement and regulation of radiation dose. The course discusses the ALARA concept, its application in dentistry, and best practices to reduce radiation exposure to the dental patient.

The necessity for diagnostic radiographs is essential, and the risk associated with these radiographs is minimal. However, all radiation exposure has the potential to cause biological damage, and radiation damage is cumulative over an individual's lifetime. Therefore, an informed dental professional who has a broad knowledge of the nature of ionizing radiation and its potential health effects is best able to convey accurate information and a professional attitude that engenders patient confidence. It is important to educate patients with regard to potential risks and how those risks should be expressed and managed as well as how they compare with other normal activities. Dental professionals should encourage patients to be risk informed and to take an active role in managing their own safety and health concerns.
