OPG

An OPG (Orthopantomagram) is a panoramic scanning dental X-ray of the upper and lower jaw. It is also sometimes called by the proprietary name Orthopantomagraph or Panorex. It shows a flattened two-dimensional view of a half-circle from ear to ear.

How is OPG performed?

The radiographer will ask you to stand in the machine and to bite gently on a covered mouth piece to steady your head. As the x-ray tube moves around your head, the imaging plate moves in the opposite direction. This generates an image where the jaw is in focus, and the skull is blurred.
