What is the purpose of the barrier method in cross infection prevention?

The barrier method in cross-infection prevention is primarily focused on preventing contamination of non-sterilisable equipment. In a dental setting, various instruments, surfaces, and devices cannot undergo sterilization without being damaged, and these items can easily become contaminated during procedures. By using barriers such as plastic wraps, sheets, and covers, dental practitioners can safeguard these surfaces from pathogens, thus minimizing the risk of cross-infection between patients and staff.

This method is vital for maintaining a safe clinical environment. It helps ensure that any infectious materials do not come into contact with equipment that cannot be effectively sterilized, subsequently protecting both patients and dental professionals. As a result, this strategy contributes significantly to the overall infection control efforts in the dental practice.
