What is the main purpose of using antiseptic techniques in radiology?

The main purpose of using antiseptic techniques in radiology is to reduce microbial load. Antiseptics are substances that help decrease the number of microorganisms on living tissues and surfaces, thereby minimizing the risk of infection during radiographic procedures. This is particularly important in dental radiography, where the potential for cross-contamination is heightened due to close contact with patients and the use of various instruments.

While sterilizing instruments is crucial, it is not the primary aim of antiseptic techniques, which focus more on controlling rather than completely eliminating all germs. Likewise, while cleaning surfaces is a vital part of infection control, it may not involve the same chemical action as antiseptics, which specifically target microbial reduction. The goal of antiseptic techniques is not to eradicate every single pathogen—this is what sterilization aims to do—but to effectively lower the microbial load to a safer level to protect both patients and healthcare providers.
