Types and Uses of Digital Radiography
Tools like Digital dental radiographs can be taken inside (intraoral) or outside (extraoral) the mouth. Intraoral X-rays include: Bitewing X-rays, which are taken with the patient biting down on film, show details of the upper and lower teeth in one area of the mouth. Periapical X-rays are used to detect root structure and surrounding bone structure abnormality Extra oral X-rays include : Panoramic (Panorex) X-rays, which require a machine that rotates around the head, show the entire mouth, including all the teeth in the upper and lower arch, in one image. Multi-slice computed tomography (MCT) shows a particular layer or "slice" of the mouth while blurring all other layers. This type of X-ray is useful for examining structures that are difficult to see clearly. Cephalometric projections, which show the entire head, help examine teeth in relation to a patient's jaw and profile. Orthodontists, specialists in aligning and straightening teeth, use cephalometric projections to develop their treatment plans. Sialography uses a dye (radiopaque contrast agent) injected into the salivary glands to visualize them on the X-ray film.
