What is an Orthopantomogram?
An Orthopantomogram, or OPG, is a special type of x-ray looking at the lower face that displays both the upper and lower teeth in a long flat line. It demonstrates the number, position and growth of all your teeth including those that have not yet surfaced.
What is Lateral Cephalometry?
Lateral Cephalometry is an X-ray taken of the side of your face with very precise positioning so that various measurements can be made to determine the current and future relationship of your mandible (jaw) to your maxilla (cheek bone) and therefore the nature of your bite. This helps to plan any orthodontic treatment if it is necessary.
Is there any preparation?
There is no special preparation needed for dental x-rays. Once you arrive, you may be asked by the radiographer to change into a gown before your examination. You may also be asked to remove jewelery, eyeglasses, and any metal objects that may obscure the images.
Procedure
During the OPG or Lateral Cephalometry the arm of the machine will rotate around your head but it will not come into contact with you. The Radiographer (technologist trained in medical imaging) will tell you to bite on a small plastic mouthpiece attached to the machine, which keeps the top and bottom rows of teeth separated. Occasionally a film may need to be repeated if there is any movement, or if the position is not exact.
Examination and Reporting Time
The procedure is brief (about 15 minutes), painless and simple, but it is vital that you keep completely still once the radiographer (technologist trained in medical imaging) has positioned you.
The images are interpreted by a Radiologist (a doctor trained to read medical images). You can either wait for your results or alternative arrangements can be made to collect them at a later stage.
