Aerosol Transmission of COVID-19 and the Impact on Dentistry

COVID-19 Research Area(s): Mathematical Modelling and Operations

Increasing evidence suggests that the SARS-CoV-2 virus can be transmitted by aerosols. Several medical procedures produce Aerosols. Dentistry in particular also produce aerosols in many of its procedures. Further, since much of dentistry is performed in non negative pressurized settings, the risk of transmission is potentially substantial. In this research project, we use a novel data set from Asia to isolate the effect of possible transmission from aerosols in dentist procedures. We then develop a model to understand how this transmission happens. Using this understanding, we look at the potential impact to dentistry as it is practiced. We use our understanding to recommend evidence based policy guidelines (and solutions) that aim to decrease the risk of transmission substantially.
