OPG, or Orthopantomogram, is a panoramic dental x-ray that produces a 2 dimensional view of the maxilla and mandible. You are required to keep still for less than 10 seconds whilst the machine rotates around your head. The image produced contains information about the teeth, gums and bones.

Preparing for an OPG

Please bring your referral (letter from your doctor/dentist) and your Medicare and/or Pension Health care card with you to your appointment. It is important to bring all previous imaging relating to the region being imaged.

No appointment is necessary. There is no other preparation required for OPG.

The radiographer may ask you to remove any metal objects such as necklaces and earrings that may interfere with the scan.


A single examination will take an average of 5 minutes.

You will be asked to rest your chin on a chin rest, bite down onto a small sterile bite piece and hold onto the handles to ensure no movement whilst the machine rotates around your head.

All OPG examinations will be performed by one of our experienced radiographers and interpreted by a radiologist.


We strongly advise that you return to your referring dentist or doctor, in order for them to discuss your OPG report with you.


Will I feel anything while having my X-ray taken?
No, x-rays are painless.

How much radiation am I getting exposed to?
X-rays are monitored and regulated so you get the minimum amount of radiation exposure needed to produce the image.

Can I have an X-ray if I am pregnant?
Babies in the womb are more sensitive to the risks of x-rays. Please inform your doctor if you are or you suspect you may be pregnant before having your x-ray.

Can I have a female radiographer/technician to perform the scan?
Yes, please let reception know when making your appointment. We have female radiographers sensitive to the needs of female patients.

Can I accompany my child in the X-ray room?
If your assistance is needed to keep your child still, we will provide you with a lead gown so you can be present in the x-ray room. However, if you are (or suspect you are) pregnant, or if you have other children with you, you will be required to wait outside the room. Babies and small children are more sensitive to x-rays and this will reduce unnecessary exposure. Instead, please bring an additional adult with you to assist.

Will the radiographer performing my scan tell me what’s wrong?
It is the radiographer’s duty to perform the test and ensure the images are of high quality for the radiologist (specialist) to interpret them.
