Digital Imaging in Dentistry: Intraoral, Extraoral, and 3D Technology Advantages of Intraoral Digital Imaging

Image quality - Grayscale resolution improved diagnostic value. Digital image formation uses gray of maximum 256 gradations compared to radiographic film which displays only gray of 16 to 25 gradations. As a result, diseases can be more appropriately detected, such as initial lesions due to operable contrast enhancement and density of dental technicians (Fig. 26). Providers can also highlight anatomical features, adjust sharpness and brightness, and change the color of the image to measure the shape (Figure 26). Due to potential legal problems, if the enhanced image does not match the original image, the manufacturer will display a warning function. We recommend that you save a copy of the original image on your computer or network server.

Save time and patient experience - Reduce the time from sensor exposure to radiation exposure and display of digital images using digital images of hard sensors. When the X-ray exposure button is pressed, the digital image appears on the computer screen when the dental provider returns to the room. Such instant viewing helps the dental provider redo the remake if applicable, and when the provider talks about the images displayed on the computer screen instead of the view box, the provider educates their patients I will help you.

Patient Safety - Sensor sensitivity to radiation requires less exposure time, so when changing from radiographic film to digital PSP, patients who rely on radiographic films used in dental care, such as F values, Radiation dose will be reduced. By using a sensor, radiation exposure time can be greatly shortened. PSP sensors require more radiation than solid state sensors. However, the radiation dose of the PSP sensor is less than that of the radiographic film. Due to the convenience of re-acquiring digital images, the dental office strongly recommends planning multiple office training that can cooperate with the manufacturer's trainer or local expert to provide training courses for employees. The time spent troubleshooting various digital receivers is beneficial for everyone, including the time to retrieve digital images.

Environment - Eliminate radiographic goods such as radiographic film and processing liquid. Digital imaging also helps reduce hazardous waste such as lead foil and silver salt

Digital dental x-rays can be taken in the mouth (inside the mouth) or outside the mouth (outside). Oral X-rays, the most commonly used dental x-rays, provide detailed information suitable for detection of tooth decay, confirmation of tooth development, and monitoring of teeth and bone health status. Extraoral X-rays do not provide details of intraoral X-rays and are not used to identify individual tooth problems. However, they are used to detect affected teeth, monitor jaw growth and development, and identify potential problems between teeth, jaws and TMJ or other facial bone.

Dental radiography is one of the most common types of radiosurgery. One prediction that has been done with dental radiography is intraoral radiography, which means placing the film inside the patient's mouth. There are 4 types in the mouth. That is, it is an engagement view, a tip view, a biting view, and a full mouth series. There is a traditional intraoral X-ray photograph, with the development of another technique, a digital intraoral X-ray photograph was developed. In this new imaging mode, radiographic film is replaced with X-ray sensor. The signals temporarily stored in the sensor are transmitted to a computer displaying images that can be stored, interpreted, manipulated, and quantized. Digital intraoral X-ray photography can be divided into two. This is two fundamental different concepts of direct digital image acquisition, based on CCD (charge-coupled device) and storage fluorescence system.

Digital radiographic images can be indirect, direct or semi-direct. Radiographs produced by flatbed scanners with transparent adapters, sliding scanners and digital cameras are called indirect digital radiographs. Direct digital images are acquired using solid state sensors such as CCD or complementary metal oxide semiconductor (CMOS) based chips. Semi-direct image charge coupling is obtained using a phosphor plate system to sequentially transfer the amount of electrons deposited on each pixel from one well to the sense amplifier and display the image on the monitor. Local digital sensor arrays are used for intraoral radiography and linear arrays are used for extraoral imaging. CMOS sensors use active pixel technology. It reduces the required system power by a factor of 100 and does not require charge transfer. The phosphor plate system consists of a polyester substrate coated with a crystalline emulsion of a cerium activated cerium halide compound.
