What is the term used to describe the technique of protecting non-sterilisable items from cross infection by the use of impervious membranes?

The technique of protecting non-sterilisable items from cross infection using impervious membranes is accurately referred to as barrier protection. This method is designed to create a physical barrier that prevents the transfer of infectious agents to sensitive items or surfaces that cannot be sterilized.

Barrier protection is crucial in dental practice, as it maintains the integrity of equipment and provides safety for both patients and healthcare providers. Utilizing impervious membranes minimizes the risk of contamination during procedures and ensures a hygienic working environment.

The other terms listed refer to different concepts related to infection control and dental practice. For instance, debridement pertains to the removal of dead or infected tissue, while the use of personal protective equipment (PPE) focuses on safeguarding the healthcare worker from exposure. Zoning generally involves organizing a workspace to enhance safety but does not directly relate to the protection of non-sterilisable items in the same way that barrier protection does.
