Résumé
Spraying during dental practices can generate quantity of droplets, which transform into droplet nuclei and suspend in the air of clinic in the form of aerosol. Either droplets or aerosols may carry microorganisms and cause air contamination in the hospital, posing potential threat to the health of clinical healthcare staff and patients. The present article summarizes some basic concepts involved in bio-aerosol research and reviews literatures on intervention measures of dental clinic droplet/aerosols to clarify whether there is experimental evidence of aerosol-carrying bacteria in the existing literatures. The aim of this article is to provide evidence for the formulation of guidelines for infection control in dental healthcare practices during the epidemic period of infectious diseases, as well as to provide reference and scientific basis for the management and implementation of infection control measures in daily dental clinical work.
