What type of PPE is recommended when performing procedures that generate aerosols?

When performing procedures that generate aerosols, the use of a high-filtration mask or N95 respirator is crucial due to the potential for airborne transmission of infectious agents. These masks are designed to filter out at least 95% of very small (0.3 micron) particles, including bacteria and viruses that may be aerosolized during dental procedures. This level of filtration helps protect both healthcare providers and patients from exposure to infectious aerosols.

In contrast, standard surgical masks do not provide the same level of protection against airborne pathogens, as they primarily protect the surgical site from contamination and are not designed to filter out small particles effectively. A surgical gown offers protection against splashes and direct contact but does not guard against inhaling aerosols. Gloves are essential for hand protection but do not provide any respiratory protection. Therefore, the high-filtration mask or N95 respirator is the appropriate choice to ensure safety during aerosol-generating procedures.
