X-rays (radiographs) are the most common and widely available diagnostic imaging technique. Dental X-rays are pictures of the teeth, bones, and surrounding soft tissues to help find problems with teeth and bone.
Radiovisiography (RVG): RVG is the latest X-ray technology in dentistry which helps in a better diagnosis. A high quality digital image can be obtained immediately. As compared to the conventional X-ray there is reduced radiation exposure to the patient.
Digital radiography: It is a novel method of medical imaging which uses digital X-ray sensors instead of conventional films to produce images. This technology provides faster imaging, detailed radiographs and quality digital images. Digital radiography constitutes a system with components that include a digital image receptor, a digital image processing unit, an image management system, image and data storage devices, interface to a patient information system, a communication network and a display device with operated controls. Digital radiographs are stored in the form of digital data and can be displayed on a computer monitor.
An Orthopantomogram (OPG) or panoramic dental X-ray can show a wide view of jaws, teeth and roots. It displays the nasal area, maxillary sinuses, jaw joints, teeth, upper jaw, lower jaw and surrounding bone on a single film. OPGs are used by Dentists to determine the status of wisdom teeth, to reveal cysts, tumours, bone irregularities and more.
