Which film is used in cassettes to provide a wide view of both the upper and lower jaws?

• A. Panoramic Film
• B. Intraoral Film
• C. Label Side
• D. Latent Image

Answer: (A)

Panoramic imaging uses a wide, curved receptor housed in a cassette and a rotating X-ray source to capture both the upper and lower jaws in one image. This setup creates a single view that shows the maxilla and mandible together, which is ideal for evaluating overall jaw structure, eruption patterns, and pathology.

Intraoral film, by contrast, is placed inside the mouth to image only a small group of teeth at a time, not the entire jaws. The terms label side and latent image aren’t film types: the label side is part of the film packaging, and a latent image is the invisible pattern formed on film right after exposure but before processing.
