Extra oral film is primarily used to evaluate what?

Extraoral films are mainly utilized to capture images of larger anatomical structures, particularly the skull. These films are specifically designed to assess and provide comprehensive views of extensive areas, which cannot be adequately visualized using intraoral films that focus on individual teeth and their surrounding tissues.

The use of extraoral films is essential in recognizing and diagnosing various conditions related to the jaw, sinuses, and other structures, making them invaluable in orthodontics and oral surgery. By capturing images from a broader perspective, dentists can accurately analyze complex cases that involve the overall skeletal structure, rather than just localized dental issues.
