The use of digital X Rays has increased considerably since its introduction to the market by Trophy in 1987 its use because it produces snapshots. This technology has a loading device inside an intraoral sensor that produces an immediate digital image on the monitor, there is a large number of digital applications in the medical area, radiology being one of the most used.
Direct digital radiography, unlike digitalized radiography, uses electronic sensors sensitive to x-rays that are placed in a similar way to the common film. The electronic sensor is connected to a computer, creating a radiological image that will be displayed immediately on the monitor. The extreme sensitivity of the sensor allows a reduction that varies from 30% in skull radiographs to 60% in panoramic and up to 90% in radiation decrease in intraoral radiographs.
