What is (OPG)

An Orthopantomogram (OPG), also known as an "orthopantogram" or "panorex", is a panoramic scanning dental X-ray of the upper and lower jaw. It shows a two-dimensional view of a half-circle from ear to ear - illustrates the maxilla and mandible, all the teeth including the "wisdom teeth," the frontal, nasal and maxillary sinus air spaces and the temporomandibular joint complex or "TMJ".

Equipment

Dental panoramic radiography equipment consists of a horizontal rotating arm which holds an X-ray source and a moving film mechanism (carrying a film) arranged at opposed extremities. The patient's skull sits between the X-ray generator and the film. The arm moves and its movement may be described as a rotation around an instant center which shifts on a dedicated trajectory.

Normally, the person bites on a plastic spatula so that all the teeth, especially the crowns can be viewed individually. The whole orthopantomogram process takes about one minute.

Digital

Dental X-rays radiology moves from film technology (involving a chemical developing process) to Digital X-ray which is based on electronic sensors and computers. One of the principal advantages compared to film based systems is the much greater exposure latitude. This means much less repeats, which also reduces patient exposure to radiation. Lost xrays can also be reprinted. Other significant advantages include instantly viewable images, ability to enhance images, ability to email images to practitioners and clients, easy and reliable document handling, reduced X-ray exposure, no darkroom is required, no chemicals are used.
