What term describes the technique to avoid cross infection by separating clean and contaminated areas?

The term that describes the technique used to avoid cross-infection by separating clean and contaminated areas is "zoning." This method involves organizing the workflow and physical space within a dental practice to clearly differentiate between contaminated (e.g., areas and items that have come into contact with patients) and clean areas (e.g., areas set aside for sterilization or where clean instruments are stored).

Zoning is crucial in reducing the risk of cross-contamination, which can occur if contaminated items come into contact with clean surfaces or instruments. By clearly designating specific zones for different functions, dental practices can establish protocols that help ensure the safety and health of both patients and staff.

This approach not only enhances infection control measures but also promotes efficiency in clinical procedures by allowing dental professionals to work within a structured environment. Thus, zoning is an essential strategy in maintaining aseptic conditions in dental settings.
