Reopening Dentistry With Complete Aerosol Suppression

Ever since the onset of the COVID-19 pandemic, the potential for transmission of virus particles through aerosol generation has had a significant impact on the delivery of dental procedures and created a heightened risk for the dental team.

For months, it seemed the problem of aerosol production in dental offices was insurmountable. That is until a team of researchers, led by Dr. Alexander Yarin, Professor at the Department of Mechanical and Industrial Engineering at the University of Illinois at Chicago, came up with a novel approach that alters the physical response of water to the rotary and ultrasonic forces that are used in dentistry.

In this breakthrough discussion with Chiraz Guessaier, Manager of CDA Oasis, Dr. Yarin presents his ground-breaking findings that may eliminate the risks posed by aerosol generation entirely. He explains the concept of risk elasticity and walks through clear video evidence of aerosol suppression. He also suggests it may not be long before this breakthrough technology finds its way into dental offices all over the world.

    Amazing concept
    I have questions regarding aerosol experiments :
    1. Equipment – does it have equipment consequences over time to drill , water line , suction ???? Clogging ,
    Increased maintenance ?? Bacterial growth in lines ????

    2. Mentioned cooling effect not altered – is this proven – much heat generation with drill . Same as regular water???
    3. Patient sensitivity potential it swallowed – safe ????

    Thank you Dr. Yarin. Here are a few questions.

    Has this solution been tested in various dental units?
    How long did this test run?
    Is there a potential for clogging the small water tubing and valves found in dental units?
    Is there a residue left on the tooth that might interfere with the set of polyvinyl siloxane impression material?
    Is a residual left on the tooth after tooth preparation that might cause inaccuracies with impression taking? i.e. yielding an altered shape to what was carved?
    Is a residue left on bone that might interfere with healing of a muco-periosteal flap?
    Has it been tested with implant integration?
    Is it easily washed away with regular water?

    These are real concerns for clinical dentistry.
    Thank you,

    Is there any interaction between the solution and different bonding agents? This is a critical question that would need to be answered as moist dentin is critical and penetration into dentinal tubules is also critical and if the liquid does not flow the same way there could be negative effects on bond strength.

    This is an interesting concept but we also need to consider what the environmental implications of releasing all these polymers into our fresh water supply and how this will affect freshwater and saltwater life that is already at critical stages of extinction. One thing Covid-19 has taught us is that we are ALL connected and our existence depends not just on the economy but also maintaining balance with Mother Nature.

    Innovative development. Of course, it is in the initial stages of development. Given that more testing for safety, efficacy and use in a human still needs to be completed. How long before a product like this makes it to market? 2 years or longer?
