Using F-speed film versus D-speed film reduces the absorbed dose by what percentage?

Using F-speed film as opposed to D-speed film significantly enhances radiographic efficiency and reduces the amount of radiation absorbed by the patient. It is well established that F-speed film requires less exposure time, which corresponds to a substantial reduction in radiation dose. Specifically, research has shown that the use of F-speed film can lead to a reduction in the absorbed dose by approximately 60% when compared to D-speed film. This reduction is critically significant in dental radiography, as it helps to minimize the radiation exposure for patients while still providing high-quality diagnostic images. This advantage not only improves patient safety but also aligns with the principles of radiation protection, emphasizing the importance of reducing unnecessary exposure whenever possible.
