The Airborne Lifetime and Spatial–Temporal Distribution of Emitted Droplets in Dental Procedures
In the setting of widespread severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) community transmission, how to mitigate the potential transmission risks in dental procedures could help the restoration of global dental services. Owing to the insufficient understanding of the droplet spatial–temporal distribution in dental procedures, the study aims to employ the laser light scattering method to investigate the emitted droplet characteristics. The ultrasonic scaling is performed in the mock-up experimental dental clinic with six air changes per hour (ACH), and the instantaneous moments of the emitted particles are recorded by a high-speed camera. The speed of emitted particles near the oral cavity could reach ab. 5 m/s, causing the high-level contaminated area within 1 m from the patients’ oral cavity. Cooperation between air purifiers and high-volume evacuation (HVE) could significantly reduce the airborne lifetime of emitted droplets. These obtained results could complement dental clinic infection control policy and practice.
