Longevity of SARS-CoV-2 : Info for Dentists
Here are some examples of the longevity of SARS-CoV-2 in relation to the dental office:
• The virus is viable up to 72 hours after application to plastic and stainless steel surfaces, like the dental chair.
• The virus is viable up to 24 hours on cardboard surfaces, like glove and mask boxes which are commonly kept in the operatory.
• The virus is viable in suspended aerosols up to three hours, like the bioaerosols created during dental procedures.
****The best defense is to use your AeroShield Aerosol Eliminator to remove aerosols before they can get into your operatory. Catch them at the source because once this virus is in the air, it is widely dispersed. Combined with the virus’s ability to live outside the body for long periods of time, this leads to high transmissibility. Keeping the virus out of the air as much as possible is the best way to decrease transmission - use AeroShield Aerosol Eliminator with every patient to reduce levels of bioaerosols in the dental operatory.

Bacterial Aerosol Contamination during Dental Scaling Treatment
This article highlights the benefits of the AeroShield Aerosol Eliminator for Hygienists...
“The results showed that bacterial aerosols contamination could spread a horizontal distance of 100 cm and a vertical distance of 50 cm from a patient’s oral cavity, and remain airborne suspended for 20 minutes.“
Facts on COVID-19/SARS-CoV-2: Info for Dentists
“In a study investigating cough aerosols, The Edmonton group demonstrated that cough aerosols are composed of droplets ranging from 0.1 to 900 microns size, of which 97 per cent were less than 1 micron in size, and 99 per cent less than 10 microns.“
**The hospital-grade HEPA filters used in AeroShield Aerosol Extractor are certified to capture particles small enough to be effective against SARS-CoV-2. Don’t be fooled by faulty filters. See details here.**

John Hopkins Medicine Article on COVID-19: Asymptomatic Shedding of Virus
- By respiratory droplets and by fomite. Virus found in respiratory secretions and saliva.
- Viral shedding by asymptomatic people may represent 25–50% of total infections.
- Viral shedding may antedate symptoms by 1–2 days.
- Viral titers are highest in the earliest phases of infection.
****We cannot assume that asympotmatic patients are not a threat. Everyone is potentially shedding virus at any given time, with or without symptoms. Don’t risk your health, use the AeroShield Aerosol Eliminator with every patient.****
Important Facts about Airborne Particles (ie:Coronavirus) for Dentists
The total allowable particle concentration - building materials, combustion products, mineral fibers and synthetic fibers (particles less than 10 microns) - specified by EPA (U.S. Environmental Protection Agency)
- 50 microns/m3 (0.000022 grain/ft3) - allowable exposure per day over the course of 1 year
- 150 microns/m3 (0.000022 grain/ft3) - allowable exposure over 24 hours
****If the concentration of airborne particles are regulated in building materials, why aren’t the concentration of bioaerosols regulated in dental offices?! Take your health into your own hands. Use AeroShield Aerosol Extractor during every procedure.****
Transmissibility of COVID-19/SARS-CoV-2 - Of Interest to Dentists
“The complete calculation of this is hampered by our non-understanding of the portion of infections which remain asymptomatic. However, based on the incidence of transmission from identified symptomatic cases to contacts, R0 for SARS-CoV-2 ranges from 1.4 to 322. This is higher than the estimated R0 for 1918 pandemic influenza23.“
****Dental professionals need to take every precaution to ensure they are not contributing to the spread of SARS-CoV-2/Covid-19. The AeroShield Aerosol Eliminator is the newest line of defense against potentially spreading the virus.****
