Negative Air Pressure Room Effect on Aerosol Distribution Patterns During Dental Procedures Using Ultrasonic Device

Ultrasonic devices aid dental procedures, producing aerosols when combined with water. Amid the Covid-19 pandemic, dental professionals face high infection risks from these aerosols. The WHO recommends using negative air pressure rooms to control aerosols in dental settings, yet the efficacy remains uncertain due to aerosols’ prolonged survival in exposed air. This study aims to elucidate the impact of negative air pressure rooms at RSKGMP Universitas Airlangga on aerosol distribution during dental procedures involving ultrasonic devices. Fluorescein and aquades were used as coolant, and root canal irrigation was conducted on tooth 11. Results revealed notable disparities in aerosol distribution patterns and quantities between negative and normal air pressure rooms. This suggests that negative air pressure rooms affect aerosol distribution differently from normal air pressure rooms. Further research is warranted to better understand these effects and optimize aerosol control measures in dental environments.
