Infection Control for Dental Assisting Practice Exam

The choice that emphasizes using high-volume suction and providing adequate ventilation is effective because it directly addresses the mechanisms through which aerosols are generated and transmitted during dental procedures. High-volume suction helps to capture and remove droplets and aerosols produced during treatments, thereby reducing the overall concentration of potentially infectious particles in the air. This is particularly important in dental practices, where procedures often involve the use of instruments that can create a significant amount of aerosol.

In addition to suction, ensuring adequate ventilation can further diminish the risk of aerosol transmission. Good ventilation systems can help disperse and dilute airborne pathogens, reducing the likelihood of inhalation by both patients and dental professionals. The combination of these two practices makes for an effective strategy to minimize the risks associated with aerosol-generating procedures.

Other methods, such as minimizing patient interactions or using low-speed handpieces, do not address the aerosol issue as directly or effectively. Minimizing interactions may have some impact but does not mitigate aerosol generation during high-risk procedures. Low-speed handpieces create less aerosol than high-speed instruments but do not eliminate it entirely, whereas effective suction and ventilation strategies directly target the issue. Avoiding the use of masks would compromise safety and increase the risk of transmission, making this approach counterproductive.
