摘要
新型冠状病毒肺炎(COVID-19)传染性极强,具有人群易感性、初期症状不明显、潜伏期长等特性。《新型冠状病毒肺炎诊疗方案(试行第七版)》中,明确指出"经呼吸道飞沫和密切接触传播是主要的传播途径,在相对封闭的环境中长时间暴露于高浓度气溶胶情况下存在经气溶胶传播的可能"。口腔诊疗过程中产生的携带大量病原微生物的气溶胶迅速成为业界关注的焦点。本文通过对口腔生物气溶胶的来源、危害及感控等方面进行文献回顾,为口腔日常诊疗期间及应对突发公共卫生事件时,口腔诊疗区动态环境中感染控制提出一些思考和建议。
The corona virus disease 2019(COVID-19)is extremely contagious,and has the characteristics of susceptibility to the population,insignificant initial symptoms,and long incubation period.The new COVID-2019 diagnosis and treatment plan(trial version 7)issued by the National Health Commission on March 3,2020.It was clearly pointed out that"Transmission through respiratory droplets and close contact are the main routes of transmission.Possibility of transmission by aerosol under the condition of long-time exposure to high concentration aerosol in relatively closed environment".A large number of droplets and aerosols which carries dozens of pathogenic microorganisms from patients are generated during dental diagnosis and treatment.And dental aerosol contamination has quickly become the focus of attention.This paper reviews the source,hazards,and infection control of dental bio-aerosols.Put forward some considerations and suggestions on the infection control in the dynamic environment of the dental clinic,during routine dental treatment and in response to public health enmergencies.
