Dental radiography is one of the most valuable tools used in modern dental health care. It helps to diagnose certain dental conditions that would otherwise be difficult to identify, and its judicious use is of considerable benefit to the patient. However, the use of dental radiological procedures must be carefully managed because X-radiation has the potential to damage healthy cells and tissues. The aim of radiation protection in dentistry is to obtain the desired clinical information with minimum radiation exposure to patients, dental personnel, and the public. There are four main concerns when dealing with radiation hazards. First, patients should not be subjected to unnecessary dental radiography. Second, patients need to be protected from unnecessary exposures. Third, it is essential that personnel in the dental office be protected from unnecessary exposure to radiation. Finally, the public requires adequate protection. This review focuses on these parameters of radiation protection in dentistry.
