An OPG is a panoramic scanning dental X-ray of the upper and lower jaws It shows a two-dimensional view of a half-circle from ear to ear. Images are computer stitched together to form a single image.

An OPG 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. It is different from the small close up x-rays dentists take of individual teeth. An OPG may also reveal problems with the jawbone and the joint which connects the jawbone to the head.

Procedure

You may be asked to remove jewellery, eyeglasses, and any metal objects that may obscure the images. You will be asked to stand with your head against the machine so that it can be adjusted for your comfort. A pair of cone shaped plastic supports are then gently positioned in each ear, rather like a pair of headphones. This aligns both ears to ensure that an exact side view of the face is obtained. You will not feel any discomfort during the procedure.

Please bring any previous x-rays with you on the day of your examination.
