An orthopantomogram (OPG) is an advanced type of dental X-ray
that provides a panoramic view of the upper and lower jaw, all of
your teeth and the joints between your jaw and skull. Dentists use
OPGs for information on impacted wisdom teeth, finding the source
of dental pain, and assessment for the placement of dental
implants.
1. Is it safe?
If you are pregnant an X-ray may not be an option. This depends
on the type of X-ray that you need to have, as the levels of
radiation exposure vary. Even though the risk to your baby is
considered low, it is likely that your GP or dentist will advise
you to postpone any unnec-essary X-rays until after giving
birth.
2. Do I need to prepare for the scan?
Dental X-rays require no special preparation. You may be asked
to remove bulky outer clothing and to remove jewellery which might
interfere with the X-ray images.
3. What happens during the scan?
You will be asked to stand in the centre of the OPG machine. You
must remain still during the X-ray so you will be asked to bite on
a disposable guide to help you keep in position. When the X-ray is
being taken, part of the machine will move in front of your face as
the im-age is formed, but the machine will not touch you.
4. How long will the scan take?
The examination takes approximately 5 minutes.
5. When do I get the results?
You will be provided with the results for your dentist at the
end of the appointment.
