What is a characteristic of fast film in dental radiography?

The characteristic of fast film in dental radiography is that it requires less exposure to produce a diagnostic image. This is a significant advantage as it reduces the amount of radiation that the patient is exposed to during the imaging process. Fast film is made of a sensitive emulsion that captures images more effectively, allowing for shorter exposure times while still yielding a quality diagnostic image. This efficiency not only enhances patient safety by minimizing radiation dose but also improves workflow in a dental practice since the speed of image capture can lead to quicker procedures. While other types of film may offer greater detail, fast film’s primary benefit lies in its efficiency in requiring less radiation exposure, making it a preferred choice in many clinical scenarios.
