Digital radiography is the latest form of X-ray imaging, which involves the use of digital X-ray sensors instead of traditional photographic film. Digital radiography helps dental professionals make the most accurate and efficient diagnoses, and quickly develop treatment plans. A small sensor is connected directly to a computer instead of a film packet. When taking X-rays, the sensor is moved from tooth to tooth. The X-rays are available immediately on the computer monitor, with no development step in between. Since the digital X-ray exposure time is shorter than conventional X-rays, the amount of X-ray radiation is reduced by up to 90 percent.
