Dental procedures using ultrasound scalers and bicarbonate cleaners significantly increase aerosol pollution. Air contamination levels worsened during procedures, indicating potential risks in dental environments.

Area of Science:

  • Dental Hygiene
  • Environmental Health
  • Microbiology

Background:

  • Dental procedures can generate aerosols.
  • Evaluating aerosol pollution is crucial for infection control.

Purpose of the Study:

  • To assess aerosol pollution levels during dental procedures.
  • To evaluate contamination from ultrasound scalers and bicarbonate cleaners.

Main Methods:

  • Conducted 15 dental procedure sessions.
  • Measured air contamination using Surface Air System and plate methods (Air Microbial Index).
  • Analyzed colony-forming units per cubic meter of air.

Main Results:

  • Initial air quality was mediocre.
  • Air contamination became very bad during procedures.

  • Post-procedure air quality remained between mediocre and very bad.

    • Conclusions:

    • Ultrasound scalers and bicarbonate cleaners contribute to significant aerosol pollution.
    • Dental office air quality deteriorates during these procedures.
    • Further research is needed to mitigate airborne contaminants in dental settings.
