Considering our recent life changing event of the COVID-19 pandemic, I think dentists could take the opportunity to make their dental offices safer when it comes to aerosol infection control. Research has shown high-speed suction to be significantly more effective at reducing aerosol contamination than the low-speed saliva ejector. Negative pressure operatories and aerosol source-capture arms could exhaust the aerosol cloud generated in the operator working zone away from the patient’s oral cavity to outside air. High speed vacuum evacuation should also be recommended for every aerosol generating dental procedure, including dental hygiene appointments.
