What type of film speed is more efficient in reducing radiation exposure?

High-speed film is recognized for its efficiency in reducing radiation exposure during dental imaging. This type of film is more sensitive to radiation, which means it requires less exposure time to produce a diagnostic image compared to slower film types. As a result, using high-speed film allows dental professionals to capture quality images while minimizing the patient's exposure to harmful radiation.

The advancements in film technology have led to ultra high-speed films being available, but high-speed film remains a standard choice because it balances image quality and safety in clinical practice effectively. Using medium or low-speed films would require longer exposure times, thus increasing radiation exposure for both the patient and the operator. Therefore, opting for high-speed film significantly optimizes safety protocols in dental radiography.
