Panoramic X-rays

Panoramic X-rays (orthopantomograms) are wraparound photographs of the face and teeth. They offer a view that would otherwise be invisible to the naked eye. X-rays in general, expose hidden structures, such as wisdom teeth, reveal preliminary signs of cavities, and also show fractures and bone loss.

Panoramic X-rays are extraoral and simple to perform. Usually, dental X-rays involve the film being placed inside the mouth, but panoramic film is hidden inside a mechanism that rotates around the outside of the head.

Unlike bitewing X-rays that need to be taken every few years, panoramic X-rays are generally only taken on an as-needed basis. A panoramic X-ray is not conducted to give a detailed view of each tooth, but rather to provide a better view of the sinus areas, nasal areas and mandibular nerve. Panoramic X-rays are preferable to bitewing X-rays when a patient is in extreme pain, and when a sinus problem is suspected to have caused dental problems.

Panoramic X-rays are extremely versatile in dentistry, and are used to:

  • Assess patients with an extreme gag reflex.
  • Evaluate the progression of TMJ.
  • Expose cysts and abnormalities.
  • Expose impacted teeth.
  • Expose jawbone fractures.
  • Plan treatment (full and partial dentures, braces and implants).
  • Reveal gum disease and cavities.

Advantages of panoramic X-rays?

The panoramic X-ray provides the dentist with an ear-to-ear two-dimensional view of both the upper and lower jaw. The most common uses for panoramic X-rays are to reveal the positioning of wisdom teeth and to check whether dental implants will affect the mandibular nerve (the nerve extending toward the lower lip).

Panoramic X-rays are an important diagnostic tool and are also valuable for planning future treatment. They are safer than other types of X-rays because less radiation enters the body.
