An OPG is a panoramic or wide view x-ray of the lower face, which displays all the teeth of the upper and lower jaw on a single film.  It demonstrates the number, position and growth of all the teeth including those that have not yet surfaced or erupted. An OPG may also reveal problems with the jawbone and the joint which connects the jawbone to the head, called the Temporomandibular joint or TMJ.

 

A Lat Ceph is a lateral or side view x-ray of the face, which demonstrates the bones and facial contours in profile on a single film. Lat Ceph x-rays are usually used in the diagnosis and treatment of orthodontic problems.

 

Cone Beam CT (CBCT) is an X-ray based on imaging technique that, like a conventional medical CT scan, provides fast and accurate visualisation of bony anatomical structures in three dimensions. However, CBCT scanning resolution is higher, with less artefact and scatter. The scan field of view can also be reduced to image smaller volumes and lower the radiation dose associated with each scan
