  4. 4. What is Panoramic X-ray? • Panoramic radiography, also called panoramic x-ray, is a two-dimensional (2-D) dental x-ray examination that captures the entire mouth in a single image, including the teeth, upper and lower jaws, surrounding structures and tissues. • The jaw is a curved structure similar to that of a horse shoe. However, the panoramic x-ray produces a flat image of the curved structure. It is typically set to provide details of the bones and teeth. • A non-invasive medical test . • The film for a panoramic x-ray is contained inside of the machine. Powerpoint Templates Page 4

  6. 6. What are some common uses of the procedure? • Commonly performed examination by dentists and oral surgeons in everyday practice and is an important diagnostic tool. • It covers a wider area than a conventional intraoral x-ray and, as a result, provides valuable information about the nasal area, maxillary sinuses, tooth positioning and gum and bone irregularities. A panoramic x-ray can also reveal the presence of an existing issue or potential problem such as: • • • • • • Advanced periodontal disease Oral cysts Tumors and oral cancer Impacted teeth Temporo-mandibular joint disorder (TMJ) Powerpoint Templates Sinusitis Page 6
  7. 7. How should I prepare? • A panoramic x-ray examination requires no • You will be asked to - wear a lead apron. - Remove your jewelry from the region being imaged, eye glasses and any metal objects that might interfere with the x-ray images. • Women should always inform their dentist or oral surgeon if there is any possibility that they are pregnant. If an x-ray is necessary, minimize radiation exposure to the baby. Powerpoint Templates special preparation. Page 7

  9. 9. How does the procedure work? • an x-ray machine produces a small burst of radiation that passes through the body, recording an image on photographic film or a special detector. • the x-ray tube rotates in a semicircle around the patient's head, starting at one side of the jaw and ending at the other side. • Rather than relying on film placed inside the mouth, a panoramic x-ray machine projects a beam through the patient onto film or a detector rotating oppositePowerpoint Templates the x-ray tube.

  10. 10. What will I experience during and after the procedure? • A panoramic x-ray exam is painless, fast and easy and may be recommended over intraoral x-rays for patients that have a sensitive gag reflex. Powerpoint Templates Page 10
  11. 11. What are the benefits vs. risks? Benefits • • No radiation remains in a patient's body after an x-ray examination. X-rays usually have no side effects in the typical diagnostic range for this exam. • Panoramic x-rays can be used for very young children since the film does not have to be placed inside the mouth. Risks • Women should always inform their dentist or oral surgeon if there is any possibility that they are pregnant. Powerpoint Templates Page 11
  12. 12. What are the limitations of Panoramic X-ray? • A panoramic x-ray does not provide precise and detailed information about each individual tooth or soft tissues, such as the muscles. • It is generally used as an initial evaluation of the bones and teeth. If further evaluation is needed, a computed tomography (CT) scan or magnetic resonance imaging (MRI) may be ordered. Powerpoint Templates Page 12
