Administrative Controls and Work Practice Considerations

Align scheduling to avoid patient therapy overlap and minimize aerosol-generating procedures to the greatest extent possible.2

  • OHCP should limit clinical care to one patient at a time whenever possible.
  • Set up operatories so that only the clean or sterile supplies and instruments needed for the planned dental procedure are readily accessible.
    • Any supplies and equipment that are exposed but not used during the procedure should be considered contaminated and should be disposed of or reprocessed properly after completion of the procedure.
  • Avoid aerosol-generating procedures whenever possible (e.g., use of dental handpieces air/water syringe and ultrasonic scalers).
    • Prioritize minimally invasive/atraumatic restorative techniques (hand instruments only).
    • If aerosol-generating procedures are necessary for dental care, use four-handed dentistry, high evacuation suction and dental dams to minimize droplet spatter and aerosols.
  • Limit the number of OHCP in the operatory to only those essential for patient care and procedure support.
  • The use of a preprocedural mouth rinses (PPMR) to reduce viral load or prevent SARS‑CoV‑2 transmission has not been clinically validated.14 Nonetheless, the use of antimicrobial PPMR (e.g., chlorhexidine gluconate, essential oils, povidone-iodine or cetylpyridinium chloride) may reduce the level of oral microorganisms in aerosols and spatter.
