ODU Dental Radiation Safety Certification Practice Test

A size #2 film is classified as intraoral because it is specifically designed to be placed inside the mouth during dental radiographic procedures. This type of film is commonly used for bitewing and periapical radiographs, providing essential images of both the teeth and surrounding structures.

Intraoral films are essential tools in dentistry for diagnosing and monitoring dental conditions. The size #2 film is larger than size #1 but smaller than size #3, making it well-suited for adults and older children, allowing for clear images that capture important anatomical details.

The classification of extraoral films, on the other hand, pertains to films that are placed outside the mouth, such as those used in panoramic or cephalometric imaging, which are designed for different imaging purposes than intraoral films. Screen films are distinct in that they are used in conjunction with a radiation-sensitive screen to enhance image quality, while lead does not refer to a type of film but to protective barriers used to shield against radiation exposure.
