Orthopantomography is a dental radiographic technique that uses X-rays. The result is orthopantomogram (OPG) - the film captures both jaws, teeth, jaw joints, maxillary sinus and nasal cavity. It is an extraoral imaging method. In dentistry we use OPG especially in the diagnosis of caries, cysts, impacted/semi-retained teeth, fractures, bone resorption (periodontics), temporomandibular disorders.
Intraoral X-ray image = "little X-ray" - picture of 1-3 neighbor teeth. This method is used to diagnose inter teeth decays and follicles, before and after root canals treatment. And always when a tooth and root detail picture is required.
This procedures are covered by health insurance.
