Area of Science:

  • Dental hygiene
  • Infection control
  • Biomedical engineering

Background:

  • Air polishing generates aerosol clouds, raising concerns about infection control and surface contamination.
  • Potential systemic effects and environmental contamination from sodium bicarbonate, water, and patient materials are concerns.

Purpose of the Study:

  • To evaluate an aerosol reduction device for use during dental air polishing.
  • To quantify the effectiveness of the device in reducing aerosol contamination.

Main Methods:

  • An in vitro study using artificial teeth on a Dentoform model.
  • Air polishing performed with and without the aerosol reduction device within a controlled enclosure.
  • Fluorescein-traced water used to quantify aerosol contamination via fluorescent spot counting under UV light.

Main Results:

  • Mean contamination without the device was 175.59 cm2.
  • Mean contamination with the device was 4.37 cm2.
  • Demonstrated a greater than 97% reduction in aerosol contamination.

Conclusions:

  • The aerosol reduction device significantly decreases contamination during air polishing.
  • The device offers a viable solution for mitigating aerosol spread in dental settings.
