These are special x-rays of the lower face, teeth and jaws. An OPG provides a panoramic view of the mouth, teeth and bones of the upper and lower jaws. The Lat Ceph results in a lateral or sideways view of the face.
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. It is different from the small close up x-rays dentists take of individual teeth. 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. An OPG may be requested for the planning of orthodontic treatment, for assessment of wisdom teeth or for a general overview of the teeth and the bone which supports the teeth.
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.
