Dental practices can significantly reduce their environmental impact by decreasing single-use plastic barriers. This initiative demonstrated cost savings and a notable reduction in carbon footprint (CO2e) for participating dental services.

Area of Science:

  • Environmental Science
  • Healthcare Management
  • Dental Public Health

Background:

  • Climate change necessitates environmental responsibility in healthcare, including dental services.
  • Single-use plastics in dentistry, such as equipment covers, may not be essential for infection control.
  • Reducing the carbon footprint of dental practices is an emerging priority.

Purpose of the Study:

  • To assess the financial and environmental costs of single-use plastic barriers in dental practices.
  • To evaluate the impact of communicating these costs on practice behavior.
  • To encourage reductions in plastic waste within the dental sector.

Main Methods:

  • A quality improvement project conducted in 12 dental practices in North London.
  • Baseline estimation of weekly costs and carbon footprint (CO2e) for single-use barrier plastics.

  • Follow-up assessment of changes made by practices three months after cost communication.

    • Main Results:

    • 10 out of 12 practices used single-use plastics at baseline, with weekly carbon footprints ranging from 0.07-27.02 kg CO2e.
    • Three practices reduced or eliminated single-use plastics, saving 46.87 kg CO2e per week.
    • Significant variation in single-use plastic barrier use was observed across practices.

    Conclusions:

    • Single-use plastic barriers in dentistry incur financial and environmental costs.
    • Current infection control guidelines lack clarity on environmental impact.
    • Dental services should reduce single-use plastics, and guidelines should incorporate environmental considerations.
