OPG and Lat Ceph

An Orthopantomogram, or OPG, is a panoramic x-ray that looks at the lower face, teeth, mandible and maxillary sinuses. This x-ray can demonstrate the number of teeth as well as their position and growth, and is particularly useful to assess teeth that have not yet surfaced.

A Lateral Cephalogram, or Lat Ceph, is an x-ray taken of the side of the face using specialised imaging equipment so that accurate measurements can be made to determine the current and future relationship of the top and bottom jaw (maxilla and mandible) and therefore assess the nature of a patient’s bite.

What to expect

You will be asked to remove any jewellery, hair ties or metal objects in the region of the head and face, before the OPG or Lat Ceph examination.

The radiographer will position you in a specially designed imaging machine. Once positioned, the dental machine will rotate slowly around your head take your dental images. For an OPG you will be asked to gently bite down on a disposable plastic bite piece; with a Lat Ceph you will be asked to bite down on your back teeth. You will be required to stay still while the x-ray images are taken. You may be repositioned to obtain other view requested.

Time required

This procedure usually take from 5-10 minutes, depending on how many different views/images your doctor has requested.


A small amount of radiation is emitted during an OPG or Lat Ceph, but it is minimal.


The report from our Radiologist will be forwarded to your doctor within 24 hours.  If there are any urgent findings, a Radiologist will notify your referring doctor immediately.
