Filtration Devices Could Make Dentist Appointments Safer During the COVID-19 Pandemic

In a new study using 3D holographic imaging, University of Minnesota Twin Cities researchers tested the effectiveness of three filtration devices that can mitigate the spread of aerosols during ultrasonic scaling, a common dental cleaning procedure. The findings could increase health safety in dental offices during the COVID-19 pandemic.

The researchers found that two of the devices—a high-volume evacuator and an extraoral local extractor—were very successful at reducing aerosol spread. This is one of the first studies to use advanced engineering imaging techniques to map the size, distribution, and mitigation of aerosols in dental offices.

The paper was published recently in the Journal of the American Dental Association, a peer-reviewed scientific publication from the world’s largest dental organization.
