Panorex® or orthopantomograms are 360 degrees photographs of the face and teeth. They propose a representation that is obscure to the naked eye. In general, X-rays reveal hidden structures (for example, wisdom teeth), demonstrate preceding signs of cavities, and show fractures and bone loss.
Panoramic X-rays are extraoral and easy to operate. Traditionally, dental X-rays require a film being placed inside the mouth. For panoramic X-rays, a panoramic film is hidden inside a device that revolves around the outside of the head.
Panoramic X-rays are only taken as needed on a needed basis.
A panoramic X-ray is not administered to give a comprehensive look at each tooth. Instead, it presents a better glimpse of the sinus areas, nasal areas, and mandibular nerve. Panoramic X-rays are favored to bitewing X-rays when a patient is in severe distress, and when a sinus problem is speculated to have caused dental problems.
Panoramic X-rays are remarkably accomplished in dentistry, and are used to:
- Evaluate patients with an acute gag reflex.
- Assess the improvement of TMJ.
- Detect cysts and abnormalities.
- Exhibit impacted teeth.
- Reveal jawbone fractures.
- Plan treatment (full and partial dentures, splints, and implants).
- Disclose gum disease and cavities.
How Are Panoramic X-rays Taken?
The panoramic X-ray gives the dentist with a full two-dimensional view of both the upper and lower jaw. The panoramic X-rays reveal the positioning of wisdom teeth and check whether dental implants will affect the mandibular nerve.
The modern equipment consists of a rotating arm that contains the X-ray generator and a revolving film attachment. The head is placed between these two devices. The X-ray generator travels around the head, taking pictures. The head and body positioning will determine how sharp, clear, and useful the X-rays will be.
Panoramic X-rays are a valuable diagnostic tool and are also useful for planning future treatment. They are safer than other types of X-rays because less radiation enters the body.
