Why avoid Aerosol Generating Procedures in Dentistry?

Aerosols can harbour micro-organisms (including bacteria, fungus and viruses). Producing dental aerosols in the dental office/ surgery can greatly increase the chance of spreading the disease. For example, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus that causes coronavirus disease 2019 (COVID-19) has been found to be stable for several hours to days in aerosols and on surfaces[1]

However, aerosol generation can be reduced and avoided altogether whilst still providing dental care by using some minimal intervention procedures or by choosing dental materials whose use does not involve generating aerosols.

Minimal aerosol generating procedures include Atraumatic Restorative Treatment, Selective and Stepwise Caries Removal and the Hall Technique.
