Panorex (Orthopantomograph) 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. Panoramic X-rays show a broad view of the jaws, teeth, sinuses, nasal area, and temperomandibular (jaw) joints. These X-rays do not find cavities. These X-rays do show problems such as impacted teeth, bone abnormalities, cysts, solid growths (tumors), infections, and fractures. Unlike bitewing X-rays that need to be taken every few years, panoramic X-rays are generally only taken on an as-needed basis.
