Panoramic X-Rays (Panorex® / Orthopantomogram)
Panoramic X-rays are wraparound images of the face and teeth, providing a broad view that cannot be seen with the naked eye. Like other dental X-rays, they can reveal hidden structures such as wisdom teeth, early signs of cavities, fractures, and bone loss.
Unlike traditional intraoral X-rays where film is placed inside the mouth, panoramic X-rays are extraoral. The film is housed in a rotating machine that moves around the outside of the head, making the process quick and comfortable.
Panoramic X-rays are typically taken on an as-needed basis. While they do not show the fine details of individual teeth, they provide a wider view of the sinuses, nasal areas, jawbone, and mandibular nerve. They are especially useful when a patient is in significant pain or when sinus issues may be contributing to dental problems.
Common uses for panoramic X-rays include:
- Evaluating patients with a strong gag reflex
- Assessing TMJ disorders
- Detecting cysts or abnormalities
- Revealing impacted teeth
- Identifying jawbone fractures
- Planning treatments such as dentures, braces, or implants
- Detecting gum disease and cavities
How panoramic X-rays are taken
The equipment consists of a rotating arm with an X-ray generator and a moving film or sensor attachment. The patient’s head is carefully positioned between these devices. As the arm rotates, it captures a two-dimensional image from ear to ear, showing both the upper and lower jaw. Images are magnified up to 30% to ensure small details are visible.
Panoramic X-rays are a valuable diagnostic tool and aid in planning future dental treatments. They also expose patients to less radiation than many other types of X-rays, making them a safe and effective option.
