Which type of film is used to capture a panoramic radiograph?

Panoramic radiographs are typically captured using extraoral film, which is specifically designed to accommodate the larger size and positioning requirements of imaging that includes a wide view of the jaws, teeth, and surrounding structures. Extraoral films are placed outside the mouth rather than inside it, which allows for the capture of the entire dental arch in a single image.

This type of film is essential for panoramic imaging because it must have the capability to record information over a broader area, which cannot be achieved with intraoral film that is designed for examination of individual teeth or limited sections of the mouth. Additionally, digital sensors can also be used in panoramic imaging, but they represent a different technology rather than a film type. The reference to 'lead film' does not apply, as this is not a recognized type of film used in dental radiography. Thus, the choice of extraoral film as the correct answer reflects its specific application and suitability for this purpose in capturing panoramic images.
