PANORAMIC & CEPHALOMETRIC
Panoramic radiography, also called panoramic x-ray, is a two-dimensional (2-D) dental x-ray examination that captures the entire mouth in a single image, including the teeth, upper and lower jaws, surrounding structures and tissues.
The jaw is a curved structure similar to that of a horseshoe. However, the panoramic x-ray produces a flat image of the curved structure. It usually provides details of the bones and teeth.
The cephalometric X-ray is a unique tool, which enables the orthodontist to capture a complete radiographic image of the side of the face. X-rays in general offer the orthodontist a way to view the teeth, jawbone and soft tissues beyond what can be seen with the naked eye. Cephalometric X-rays are extraoral, meaning that no plates or film are inserted inside the mouth. Cephalometric and panoramic X-rays display the nasal and sinus passages, which are missed by intraoral bitewing X-rays.
Cephalometric X-rays are usually taken with a panoramic X-ray machine. The adapted machine will have a special cephalometric film holder mounted on a mechanical arm. An X-ray film is exposed to ionizing radiation in order to provide the dentist with pictures of the entire oral structure
