OPG

OPG stands for Ortho Panthograph. This also is an x-ray test and is useful for patients who are unable to open their jaw, for giving a complete view of both jaws on a single film, in checking third molar / wisdom tooth, development of teeth in mixed dentition (upto 12 years), and for orthodontic cases.

The entire procedure of OPG takes about 20-30 minutes. Earrings, nose rings and hair pins should be removed prior to the test. The patient is made to rest his chin on a chin rest with the head held stationery and the OPG is taken.
