X-Ray - Dental Imaging

There are several different types of x-ray your dentist or doctor may refer you for.

These include:

  • OPG
  • Lateral cephalostat (CEPH)
  • Intraoral views
  • Cone beam VT
  • Bone Age

There is no preparation required prior to arriving for a dental x-ray.You may be required to remove your jewellery and dentures/plates.

  • OPG

    An OPG is performed standing in an OPG X-ray machine. You will be asked to bite gently on a small tab or place your chin on a small rest. The Radiographer will position you head and teeth in the ideal position before gently bracing your head in place. The X-ray equipment slowly rotates around your head during the scan. The scan is completed in 15 to 20 seconds.

  • Lateral Cephalostat (Lateral CEPH)

    Lateral cephalostat X-rays are also performed standing using equipment that is an extension of the OPG X-ray machine. You will be asked to stand with your molars (back teeth) gently closed together and natural resting posture of your head, neck and shoulders. Markers are placed gently in the ears and on the bridge of your nose. These markers allow for precise positioning and measuerments for your Orthodontist.

  • Intra Oral (including bite wings and full mouth surveys)

    Intra oral X-rays are performed sitting in a chair. A small X-ray film (just a few cms in size) is placed gently into your mouth and your jaw closes to hold this in position. The X-ray equipment is positioned close to your jaw and after exposure the film is removed. Intra oral X-rays may be performed in a range of different series requested by your Dr. These usually require many views at different positions and angles.

  • Cone Beam VT

    A Cone beam VT provides a much more detailed 3D view of your mouth. For this test you will be asked to bite gently on a positioning tab or place your chin on a small rest as with an OPG. The Radiographer will position your head and teeth in the ideal position before gently bracing your head in place. The X-ray equipment slowly rotates around your head and the scan is completed in 15 to 20 seconds. Some processing is required after the 3 dimensional image is obtained before the images are complete.

  • Bone Age

    Bone age x-rays help your Doctor estimate the maturity of a child’s skeletal system. A single X-ray of one hand is required as well measurement of the patient’s height. A Radiologist then reviews the X-ray with the age and height measurements they can estimate the skeletal maturity of the patient.
