There are two primary types of digital X-ray systems used in dental practices: intraoral and extraoral. Intraoral digital X-ray systems use sensors placed inside the mouth to capture images of individual teeth. Extraoral systems, on the other hand, capture images of the entire dental arch or skull, providing a broader view of the oral and facial structures.
Intraoral digital X-ray sensors are small, flat devices that are placed directly in the mouth to capture images. These sensors are more comfortable for patients compared to traditional X-ray film, as they eliminate the need for biting on sharp film holders.
