Dental Imaging | Cone Beam CT and OPG

Dental Imaging is done to identify specific areas of the mouth, jaw or face area. A Dentist, GP or Specialist may refer depending on the purpose of the scan

What is the test for?

An OPG (Orthopantomagram) (all locations) is a panoramic scanning dental X-ray of the upper and lower jaw. When the film is developed the image is able to be seen in contrasting colours. The bone appears as a white shade, while any soft tissue or fracture will appear as a light grey or white shade.

A Cone Beam CT (only in Rockhampton and Coffs Harbour) is a special type of x-ray machine used in situations where regular dental or facial x-rays are not sufficient. It is not used routinely because the radiation exposure from this scanner is significantly more than regular dental x-rays

 

What is the preparation for the test?

None

How is the test performed?

You will be asked to position yourself in order to take the image of the affected area and the technician will assist you with this. You will be asked to keep perfectly still for a short moment in order that the x-rays can be taken as required.

Will I feel anything?

You will not be able to feel the x-ray being taken. You may feel some discomfort during the position depending on your condition.

How long will it take?

About 10 minutes
