Protective efficacy of different PPEs in reducing human coronavirus transmission during aerosol - generating dental procedures.

We evaluated the protective efficacy of different types of personal protective equipments (PPEs), with or without High-Volume Evacuator (HVE) or hydrogen peroxide-based spray, in reducing human coronavirus transmission during aerosol-generating dental procedures.
While the importance of mask disposal and shield disinfection after any patient were confirmed, the combination of PPE and face shield drastically decreased the risk of human coronavirus transmission during aerosol generating dental procedures. The addition of a 0.5 vol% H2O2 cooling spray might reduce such a risk close to zero. No differences were observed between surgical masks and FFP2/FFP3 respirators, with or without HVE.
