Congratulations to the dental profession. We won the lottery. According to data from the Occupational Information Network, dental hygienists are the most likely of all health care workers to contract SARS-CoV-2 in the workplace and dentists and assistants are right behind them!
This is primarily because of the aerosols we create when using ultrasonic scalers and highspeed handpieces. According to The New England Journal of Medicine, viral particles stay contagious in the air for 3 hours or more. While an N95 mask (or KN95) is probably our best personal protection, ultra-low volume fogging with a hypochlorous acid solution is our best option at this point to “clean” the air.
