COVID-19: Part 2—Is there something in the air? Aerosols and infection prevention/control in the dental office

This course seeks to review up-to-date infection control recommendations and emerging evidence for ongoing infection control when delivering dental care, particularly in relation to the SARS-CoV-2 (COVID-19) pandemic.

3 CE Credits

Abstract

Dental procedures that employ handpieces, lasers, electrosurgery units, ultrasonic scalers, air polishers, prophy angles, hand instruments, and air/water syringes can create bioaerosols and spatter. Ultrasonic scalers and high-speed handpieces produce more airborne contamination than any other instruments in dentistry. Furthermore, the personal protective equipment (PPE) that dental professionals generally use was selected to prevent infections related to blood-borne pathogens. As dental procedures and technologies have evolved, the incidence of aerosol-creating procedures has increased. Inhalation of airborne particles and aerosols produced during dental procedures may cause adverse respiratory health effects and bidirectional disease transmission. While transmission-based precautions may minimize risk to dental healthcare providers, many of these precautions may not be routinely practiced, and current scientific evidence and recommendations to dental healthcare providers are rapidly evolving. During the initial pandemic stage, limiting practice to essential services and practicing high-level infection control is critical, but as this pandemic evolves, we are likely to reach a state wherein endemic conditions for SARS-CoV-2 continue to exist, and our infection control may have to evolve to reflect such changes. Going forward, dental healthcare providers should be aware of invisible risks within their operatories and stay abreast of evolving infection prevention protocols before, during, and after patient care. This course seeks to review up-to-date infection control recommendations and emerging evidence for ongoing infection control when delivering dental care, particularly in relation to the SARS-CoV-2 (COVID-19) pandemic.

Educational objectives

Upon completion of this course, the dental professional should be able to:

  • Explain the risk factors and basic properties of aerosols generated during routine dental procedures
  • Describe what types of dental procedures result in significant dental aerosol production
  • Understand the types of pathogens and resultant illnesses associated with such aerosols
  • Differentiate between standard and transmission-based precautions and their utility in the dental office for safe delivery of care
  • List infection control and aerosol mitigation techniques that may reduce the risk of cross-contamination to patients and providers
