Which one of the following options is the most effective infection control method to prevent direct cross infection from one patient to another?

The most effective infection control method to prevent direct cross-infection from one patient to another is zoning. Zoning is a strategy used in dental practices to create designated areas for specific procedures or patient interactions. This method helps to limit the potential for cross-contamination by controlling the flow of patients and instruments within the practice. Each area can be managed with specific protocols to ensure that infection control practices are consistently followed.

By segregating zones for different activities, such as treatment areas, sterilization spaces, and waiting areas, dental professionals can minimize the risk of pathogens spreading between patients. This approach allows for effective cleaning and disinfection processes to be implemented in specific zones, significantly reducing the likelihood of cross-infection.

While handwashing, sterilization, and wearing gloves are essential components of infection control and contribute to overall safety, they may not fully prevent cross-infection on their own. Handwashing is vital for maintaining personal hygiene, sterilization is critical for reprocessing instruments, and gloves act as a barrier during procedures. However, without an overall strategy like zoning to structure patient flow and interactions, the risk of transmitting infections between patients remains higher. Zoning serves as a comprehensive approach to avoid direct cross-infection, reinforcing the importance of organizational protocols alongside personal hygiene practices
