The use of E-speed film instead of D-speed film reduces the absorbed dose by what percentage?

E-speed film, also known as extended speed film, is designed to be more efficient at capturing images compared to D-speed film. The primary distinction between these two types of film lies in their sensitivity to radiation; E-speed film requires less radiation exposure to produce a diagnostic-quality image.

The significant reduction in absorbed dose when using E-speed film, specifically around 50%, highlights its advancements in technology, allowing practitioners to minimize radiation exposure to patients while still achieving the necessary image quality for effective diagnosis. With this reduction, not only are patients better protected from the potential risks associated with radiation, but dental professionals can also streamline their radiographic procedures due to less exposure time required to obtain high-quality images.

This efficiency underscores the importance of selecting appropriate radiographic materials that not only deliver effective diagnostic results but also prioritize patient safety.
