Aerosols in Dentistry
Studies have shown that aerosols generated from a patient's mouth can contain up to 100,000 bacteria per cubic foot of air. Many diseases such as tuberculosis, influenza, severe acute respiratory syndrome can be transmitted during routine dental procedures via aerosolization of fluids. There is nothing a dental office can do to prevent the creation of aerosols.
Oral Microflora Associated with Respiratory Infections:
The risks dental care professionals face of contracting transmittable diseases from aerosolization of body fluids during routine procedures are not new, but increased concern over COVID-19 has brought attention to an area of dentistry that has been overlooked before.
This is mainly because the aerosol particles of COVID-19 pose an even greater threat than those of other transmittable diseases. The size of these ultra-fine viral particles can enter the bloodstream and target organs such as the heart and brain.
Most aerosol containing infectious agents originating from the patient remain 36” from the patient’s face. These aerosols, as well as spatter, pose a threat to the dentist and other staff members in proximity. COVID-19 aerosols have been estimated to travel up to 20 feet.
Additionally, COVID-19 remains viable in aerosols for 3 hours or more around your dental chair, posing a risk to the multiple patients and dental care staff exposed in that time frame. Aerosols will continue to settle on instruments and furniture in that time. COVID-19 stays on stainless steel and plastic surfaces for up to three days.
Further, we know that people infected with COVID-19 may not have any visible symptoms, but still have the potential to transmit the virus. Risks of "super-spreading events" increase when aerosols are produced during routine dental procedures on an asymptomatic patient, as their is no way to tell if postponement of treatment is necessary.
ADA and OSHA recommendations
So, what do the ADA and OSHA recommend for aerosol control and safety for dental professionals during this time? There advice on the matter has been quite limited. Essentially, both recommend reducing or eliminating procedures that produce aerosols. In today's dental clinic, that eliminates quite a bit.
If aerosol producing procedures are necessary, both the ADA and OSHA recommending using dental dams with HVE suction. While the standard of care in some circumstances, dental dams are not appropriate or convenient in every situation. Additionally, if you are trying to reduce the amount of dental care staff exposed to aerosols, four-handed dentistry is counterproductive. Further, dental hygienists using ultrasonic scalers produce a high amount of aerosols and do not have an extra set of hands for HVE aerosol control.
Studies have shown that using high-volume isolation systems are equally or more effective at reducing spatter and aerosols during your dental procedures when compared to dental dams and HVE suction as recommended by OSHA and the ADA.
Additionally, high-volume isolation systems are much more practical and convenient than dental dams and HVE Suction. They are easy to use for a variety of clinical applications performed both by dentists and hygienists and offer continuous, hands-free uninterrupted suction and aerosol control properly placed at the source of production.
Increase the standard of care recommended by the ADA and OSHA and take extra precautions with research-based approaches to aerosol reductions.

A research-based approach to reducing aerosols and spatter by 90%
Several researchers have found that using High Volume Evacuation (HVE) significantly reduces aerosols and spatter generated during routine dental procedures.
Greatly decrease the possibility of transmission of communicable diseases from patients through reduction of contaminated aerosolized fluids.
High-performance isolation systems surround your work area with continuous HVE suction, reducing aerosols by 90% or more right at the source.
Using continuous, well-placed HVE suction is one way you can reduce risks to yourself, your staff and your patients from infectious particles in aerosols. The VacuLUX HVE adapter and the VacuVUE HVE Mirror make adding aerosol control to your clinic simple, portable and affordable.
Two convenient options for Using HVE for aerosol and spatter reduction:
The VacuLUX HVE Adapter for
Reduce aerosols and spatter hands-free by placing continuous, high-volume suction in the mouth where they originate. Minimize the creation of and exposure to aerosols for when you have to work by yourself.
The VacuVUE HVE Mirror for
clear clinical views and retraction
Combine properly placed, continuous HVE suction to reduce aerosols and spatter with the practical use of a dental mirror that offers clear clinical views and retraction single-handedly.
