“It is a testament to how incredible the University of Minnesota and M Health communities are,” Uppgaard reflected, “that at a time of great stress, we can come together and work toward excellent patient care and the safety of our teams.”
At the same time, School of Den- tistry researchers began to suspect what we would soon confirm: that this new virus was spread through
aerosol droplets. Facing a new threat that dental safety practices were
not equipped to mitigate, Interim Associate Dean for Patient Care
and Clinical Services Paul Olin, DDS, MS, brought together a team of oral health and engineering professionals to determine how providers might be able to protect themselves and their patients.
Olin connected with Paul Jardine, PhD, a professor of diagnostic and biological sciences who studies bacteriophages, to simulate the transmission of aerosolized virus particles in a variety of dental prac- tice circumstances. They teamed up with Judy Danielson, MDH, clinical professor of developmental and surgical sciences in periodontology, to test dental procedures and
their production of aerosols on a mannequin.
To further understand how those aerosols might move throughout the room and possibly infect individuals, as well as how devices like a vacu- um or HEPA filter might stop that spread, the team worked with Gary Anderson, DDS, MS, a professor of

developmental and surgical sciences who studies clinical measurement, and School of Engineering faculty, including Qisheng Ou, PhD, Jiarong Hong, PhD, David Nedrelow, PhD, and David Pui, PhD. The team oversaw optical imaging through digital inline holography and laser sheet imaging to explore how devices like a saliva ejector, a high-volume extractor or an extra- oral local extractor might reduce the risk of infection. Meanwhile,
