A film that is used outside the mouth is referred to as what type of film?

The correct classification for a film that is used outside the mouth is extraoral film. Extraoral films are designed to capture images of areas of the jaw and skull from outside the patient's mouth, making them suitable for diagnostic purposes that require a broader view than what intraoral films can provide. This type of film is often utilized for radiographic imaging techniques such as panoramic imaging, cephalometric analysis, and other assessments that need to examine the overall structure of the facial skeleton.

In contrast, intraoral films are specifically used inside the mouth and are designed to capture images of individual teeth and supporting bone structures. Screen films are typically used in conjunction with intensifying screens to enhance image quality but may also pertain to extraoral contexts. The term dental film is a general descriptor that can apply to both intraoral and extraoral films, but it doesn’t specify the location of use. Thus, extraoral is the precise term for films used outside the mouth, making it the correct answer.
