An Orthopantomogram (OPG) is an x-ray picture taken in a panoramic view that is shown on a single film. This allows the dentist to view the upper and lower jaw, and all the teeth on one picture.
A Lateral Cephalogram is a side-view x-ray of the face showing the bones and facial contours in profile on a single film.
No preparation is required.
The radiographer will ask you to remove all metal objects such as necklaces and earrings as they interfere with the quality of the images.
For an OPG, you will be asked to bite gently on a peg with your front teeth. Whilst the image is being taken, the machine will rotate slowly around you. It is essential to keep still otherwise the image may appear blurred.
For a Lateral Cephalogram, a pair of cone-shaped plastic supports are gently positioned in each ear. This aligns each side of the face to ensure an exact side view of the face is obtained.
This examination takes approximately 5 to 10 minutes to complete.
