Is a panoramic or wide view x-ray of the lower face, which displays all the teeth of the upper and lower jaw on a single film. It demonstrates the number, position and growth of all the teeth including those that have not yet surfaced or erupted.
You should arrive 15 minutes before your appointment time to complete all necessary paperwork.
No other preparation is required for an OPG.
Bring any previous x-ray films with you to the appointment in case they are needed for comparison.
The patient’s chin is placed on a chin rest. The jaws are held in place by biting down on a small disposable plastic guide. Most OPGs are performed with the patient standing. During the exposure, the X-ray tube and film cassette rotate around the jaws. An exposure lasts a few seconds during which time the patient must remain still. The film cassette is then removed to allow development of the exposed X-ray film. If a lateral cephalogram is required, the head is placed in a special support on the end of the lateral cephalogram attachment for accurate positioning and an X-ray obtained.
