Which statement best describes the role of a high-volume evacuator during aerosol-generating procedures?

• A. High-volume evacuator reduces aerosols and moisture, improving visibility.
• B. Saliva ejector reduces aerosols and moisture.
• C. Air purifier reduces aerosols.
• D. Handpiece nozzle reduces aerosols.

Answer: (A)

Capturing aerosols at the source is the key idea. A high-volume evacuator works by placing its tip very close to the aerosol-producing site (the drill or ultrasonic tip) and applying strong suction to remove the particles and accompanying moisture as they’re generated. This dramatically lowers the concentration of airborne aerosols in the operator’s breathing zone and on the dental team’s field of view, which keeps the Work area clearer and safer. A saliva ejector, by contrast, provides only light suction and mainly handles saliva and pooled moisture, not the fine aerosols created during aerosol-generating procedures. An air purifier operates in the room to clean the air but doesn’t capture aerosols at the source while the procedure is ongoing. The handpiece nozzle isn’t designed to remove aerosols and can even contribute to spray if not effectively managed with suction.
