With digital radiographs, film is replaced with an electronic sensor or a phosphor plate that can be scanned. The x-rays hit the pad the same way they hit the film. This technology reduces x-ray exposures by 3 to 10 times compared to conventional X-ray film. The images are rapidly processed and stored using a computer without the environmental problems associated with photographic darkroom chemistry. One of the main advantages to the Patient with digital radiography is the ability to for the images to be quickly displayed at the dental chair for viewing and large enough to allow discussion of any conditions they may show. In short, radiographs are an important role in doctor/patient co-diagnosis.
