Panoramic X-rays, also known as Panorex® or orthopantomograms, offer a comprehensive view of the face, teeth, and surrounding structures. They are valuable for detecting wisdom teeth, early cavities, fractures, bone loss, and assessing sinus areas and the mandibular nerve. These X-rays are obtained externally, requiring the patient's head to be positioned in a rotating device. Unlike bitewing X-rays, they are performed as needed, providing a broader perspective of oral health.
Panoramic X-rays play a vital role in dentistry, serving various purposes such as:
- Evaluating the progression of TMJ (temporomandibular joint) issues.
- Detecting and exposing cysts and abnormalities.
- Identifying impacted teeth and their positions.
- Revealing jawbone fractures and injuries.
- Assisting in treatment planning for full and partial dentures, braces, and implants.
- Diagnosing gum disease and cavities.
- Assessing patients with an extreme gag reflex, providing a more comfortable examination option.
How are panoramic X-rays taken?
The panoramic X-ray provides a comprehensive, two-dimensional view of the upper and lower jaws, spanning from ear to ear. It is frequently utilized to evaluate wisdom teeth positioning and the potential impact of dental implants on the mandibular nerve, which extends towards the lower lip.
The Panorex equipment consists of a rotating arm housing the X-ray generator and a movable film attachment to capture images. The patient's head is positioned between these components. The X-ray generator revolves around the head, capturing images from various angles to ensure precise alignment. The sharpness and clarity of the X-rays are influenced by the patient's head and body positioning. These images are magnified by up to 30% to reveal even the smallest details for the dentist's examination.
Panoramic X-rays are invaluable for diagnosis and treatment planning. Compared to other X-ray types, they involve lower radiation exposure, making them a safer option for patients.
