Also known as OPG (orthopantomogram) or Rotational radiography is a wonderful method of recording an image of all the teeth and their positions in your mouth at one single time. Also, the radiation exposure is lower than having individual X-rays taken of different segments of your mouth.

ADVANTAGES:

Broad anatomic region is imaged
Low radiation dose
Convenient, easy and fast
The entire procedure takes 14 seconds expsure time
Procedure can be performed on patients who cannot open their mouth
Easy for edentulous patients, patients who do not tolerate intraoral procedure well, patients with multiple tooth / Oral pathology
No overlapping of facial bones
