摘　　要：口腔操作因喷溅可产生大量飞沫,进而转化为飞沫核以气溶胶的形式悬浮留存于诊室空气中。飞沫和气溶胶均可能携微生物造成院内的污染,对临床医护人员及患者健康造成潜在威胁。本文通过对生物气溶胶研究领域涉及的一些概念和口腔诊室飞沫和气溶胶的干预措施进行文献回顾和梳理,以明晰现有文献资料中是否有气溶胶携菌的试验证据,为传染病疫情期间口腔临床工作的防控策略制定提供指导,也为日常口腔诊疗工作的院感管理和防控措施的实施提供参考。Spraying during dental practices can generate a large number of droplets,which may 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 the present review article is to provide evidence for the formulation of guidelines for infection control in dental healthcare practices during the pandemic 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.
