Reducing single-use plastics in dental practice: a quality improvement project

Introduction Climate change is a major issue facing the global population. Healthcare services, including dentistry, have an obligation to examine current practice and reduce the carbon footprint of their services. Single-use plastics, for example, those used to cover dental equipment, are not necessarily essential for cross-infection purposes.

Materials and methods This quality improvement project was carried out in 2023 across 12 dental practices in the North London dental foundation training scheme. Baseline financial and environmental costs were estimated for the weekly single-use barrier plastics used in each practice. This was communicated to each practice. Practices using single-use plastics were contacted three months later to see if they had made any changes.

Results In total, 10 out of 12 practices were using one or more of the single-use plastics at baseline, with an estimated carbon footprint ranging from 0.07-27.02 kg carbon dioxide equivalent (CO2e) per week. Three practices reduced or eliminated their single-use plastics as a result of this quality improvement project, which resulted in an equivalent saving of 46.87 kg CO2e per week.

Discussion and conclusion The use of single-use plastic barriers varies widely between dental practices and is associated with a financial and environmental cost. Infection control guidelines are unclear with their recommendations. The authors urge dental services to reduce their single-use plastic barriers and would encourage infection control guidelines to consider the environmental impact when making recommendations.
