Aerosol behavior study

The study and report says. "Dental procedures often produce aerosol and splatter which have the potential to transmit pathogens such as SARS-CoV-2. The objective(s) was to develop a robust, reliable and valid methodology to evaluate distribution and persistence of dental aerosol and splatter, including the evaluation of clinical procedures."

The results:

  • Contamination was highest within 1.5 m from patient

  • Aerosol was measured at a max distance of
    4 m away

  • High Volume Extraction (intra-oral) only reduced aerosol airborne by up to 75%

  • Low levels o aerosols were measured at up to 60 minutes after procedure

  • With 6.5 air changes per hour, room was effectively clean after 30 minutes
