Digital radiography is the most common advanced dental technology that patients experience during diagnostic visits. The earliest uses of the computer in dentistry were in the business office and accounting. This chapter includes the discussion of some basic oral radiology terms, both conventional and digital. There are several principles of radiation safety: As Low As Reasonably Achievable (ALARA), justification, limitation, optimization, and the use of selection criteria. The chapter reviews these and then discusses how digital radiography plays a vital role in the improved safety of modern radiography. Dental cone beam computed tomography (CBCT) is arguably the most exciting advancement in oral radiology since panoramic radiology in the 1950s and1960s and perhaps since Roentgen's discovery of X-rays in 1895. Low dose CBCT protocols can potentially bring the radiation dose of CBCT into the realm of panoramic imaging.
