The full form of OPG in Dentistry is Orthopantomogram. This is most commonly referred to as OPG X- ray, and it is a panoramic X-ray of the full mouth. The X-ray displays the complete jaw along with all the teeth. The advantage of OPG is that it also shows the teeth that have not erupted (for example ? wisdom teeth). In addition, you can also get a view of the jawbone and the temporomandibular joint with the help of an Orthopantomogram.
During OPG, a short blast of a low-level X-ray is given to create the image of bones and teeth. There is a revolving mechanism which revolves around the emitter and the film to get the X-ray. It is important to keep the head and the mouth steady during the X-ray. The process is useful during the diagnosis and orthodontal procedures. Even if you are getting invisible braces (for example ? invisible aligners), your doctor will request you get an OPG Scan. The procedure is quick and painless.
The other full forms of OPG are Osteoprotegerin, Ocular Pneumoplethysmography, Oculoplethysmography, Objective Performance Goal, Office of Problem Gambling, Office of the Public Guardian, Oocysts per gram, Optic Pathway Gliomas, Oral Pyogenic Granulomas and Oral Pulse Granuloma.
