Which practice most effectively reduces aerosol generation during pediatric dental procedures?

• A. Using high-volume suction and rubber dam.
• B. Relying solely on personal protective equipment.
• C. Limiting chair time to under 5 minutes.
• D. Using only hand instruments.

Answer: (A)

The most effective way to limit aerosol spread in pediatric dental procedures is to control aerosols at the source and contain them at the operatory. Using high-volume suction captures a large portion of aerosols and droplets as they are produced, reducing how far they travel and how much contaminant becomes airborne. Pairing this with a rubber dam isolates the tooth from saliva and blood, dramatically reducing the amount of contaminated material that can become part of the aerosol or splatter. The combination provides a dual protection: cut down generation at the source and seal off the field to prevent contamination from escaping.

Relying on PPE alone is essential for protection but doesn’t prevent aerosols from being generated or spread; they can still escape and contaminate surfaces or be inhaled. Limiting chair time may reduce overall exposure but does not address how much aerosol is produced during the procedure. Using only hand instruments can eliminate aerosol from drilling, but is not practical for most pediatric treatments and does not cover all necessary procedures.
