The strategy to reduce the risk of novel coronavirus pneumonia transmission via aerosol in dental practice

The novel coronavirus pneumonia (COVID-19) has spread nationwide since its outbreak in Dec. 2019. The long exposure to high concentration of aerosols in enclosed environment could increase the risk of COVID-19 infection. The aerosol generated by dental procedures is a risk factor of cross-infection. Managing the aerosol in dental office according to its properties would be beneficial for the prevention and control of cross-infection. Based on the currently available literatures, we summarized the methods to decrease the risks of aerosol transmission. This study could provide information and recommendations for the management of aerosols in dental practice. Key words: novel coronavirus pneumonia; aerosol; dental treatment; infection control
