The correct answer is: Panoramic film

The correct answer, panoramic film, is considered a type of extraoral film because it is designed to capture a broad view of the jaw, teeth, and surrounding structures on a single image. This type of film is particularly useful in orthodontics, oral surgery, and evaluation of the temporomandibular joint (TMJ), as it provides a comprehensive overview of the oral and facial anatomy that can't be captured with standard intraoral films. Extraoral films are taken outside the mouth, using a special dental X-ray machine that positions the film at a set distance from the patient's head. Panoramic films are a common choice because they simplify the imaging process, allowing clinicians to assess multiple structures simultaneously. In contrast, the other options either refer to specific applications or types of films not categorized as extraoral, where intraoral films are taken from within the mouth.
