Introduction:

COVID-19 has the potential to spread during dental procedures via a number of routes. Clinical dentistry poses an exposure risk to dental professionals and patients. The dissemination of microbes from the patient’s mouth to the clinician can occur in three possible ways: direct contact with contaminated droplets; indirect contact with contaminated surfaces or instruments; and close-range aerosol transmission during dental aerosol-generating procedures (AGPs).

To protect the dental team and patients from infection transmission, a comprehensive infection prevention and control protocol is recommended, including hand hygiene, instrument and hard-surface decontamination, use of appropriate personal protective equipment (PPE), triaging and risk universally applicable to all dental procedures.

Aerosols in dental procedures are typically defined as particles smaller than 5μm that can remain suspended in the air for hours. As a result of risks associated with COVID-19, routine use of Fallow Time to allow for settling of suspended aerosol has been recommended following AGPs and as such, limiting the capacity for the provision of dental care. Due to the lack of experimental data on aerosols produced during dental procedures, there is no consensus on the Fallow Time required after AGPs. A recent rapid review of international dental guidance documents found that less than half referred to an FT, which varied between 2 and 180 minutes.

Aims and Objectives:

The aims of the webinar are to discuss the research on AGPs in dentistry and recommendations on

mitigating risks in dentistry during the COVID-19 pandemic.

Learning Outcomes:

At the end of the webinar the participants should be able to:

  • Describe the aerosol and splatter generated during various dental procedures
  • Understand the effectiveness of ventilation in the removal of aerosol after AGP
  • Understand the various mitigating factors in reducing the aerosol during and after AGP
