Course Number: 619

Assessment of Risk Mitigation Strategies During COVID-19

Aerosol-generating dental procedures including utilization of high-speed handpieces and ultrasonic scaling have demonstrated droplets between 25 and 50mm in diameter that are distributed up to 2.4m (8 ft) away from where they are generated.109 Given this distribution, mitigation strategies have focused on 1) reducing microbial loads in the droplets, 2) evacuation procedures to reduce aerosol and splatter, and 3) personal protective equipment.
