Principal Advantage of Panoramic Images

  • Broad coverage of facial bones and teeth.
  • Low patient radiation dose.
  • Convenience of examination for the patient (films need not be placed inside the mouth).
  • Ability to be used in patients who cannot open the mouth or when the opening is restricted e.g.: due to trismus.
  • Short time required for making the image.
  • Patient’s ready understandability of panoramic films, making them a useful visual aid in patient education and case presentation.
