What is the effect of collimation on patient exposure during dental radiography?

Collimation significantly impacts patient exposure during dental radiography by decreasing exposure. Collimation involves using a lead or other opaque material to restrict the size and shape of the X-ray beam to the area of interest. By limiting the beam's size, fewer surrounding tissues are irradiated, which consequently reduces the overall dose of radiation that the patient receives.

This technique helps to focus the radiation on the specific area being imaged, leading to more precise images and minimizing unnecessary radiation to adjacent structures. As a result, collimation is an essential practice in dental radiography as it not only optimizes image quality but also prioritizes patient safety by reducing unnecessary exposure.

This understanding is fundamental for interpreting radiographic images and recognizing the importance of safety protocols in radiographic practices.
