Aerosol Control in the Dental Hygiene Appointment
Reduce aerosol exposure with pre-procedural rinsing, high-volume evacuation, and barrier protocols that protect everyone.
Understanding the Risk
Ultrasonic and polishing procedures generate visible spray and invisible aerosol. A layered control strategy protects the patient, the operator, and the team.
A Layered Control Strategy
- Use a pre-procedural antimicrobial mouthrinse for 30-60 seconds.
- Position high-volume evacuation close to the operative site.
- Apply surface barriers to exposed touchpoints and disinfect between patients.
Engineering and Work Practice Controls
Combine HVE with rubber dam where feasible and ensure operatory air handling is adequate. Work practice controls, including proper technique and scheduling, complement engineering controls.
Practical Takeaway
Layer pre-procedural rinsing, high-volume evacuation, and surface barriers. No single control eliminates aerosol, so combine engineering and work-practice controls.
