Which of the following practices is essential for effective infection control in a dental office?

Regularly replacing surgical masks is essential for effective infection control in a dental office because masks serve as a barrier to prevent the transmission of infectious agents from the dental professional to the patient and vice versa. Masks can become moist from breathing, speaking, or aerosol procedures, which diminishes their effectiveness and can lead to contamination. By replacing surgical masks frequently, dental professionals ensure that they maintain optimal protection against airborne pathogens and reduce the risk of spreading infections. This practice aligns with infection control guidelines and helps maintain a safe environment for both patients and healthcare providers.
