Abstrakt: Objectives: To quantify (by number and mass) single use plastic waste generated from the provision of oral healthcare in primary and secondary care clinical dental settings in the UK.
Methods: An observational study of four dental practices and the clinics of a UK undergraduate dental teaching hospital was conducted. A range of routine common procedures were observed by trained and calibrated observers; these were: Examinations, endodontics, periodontics, direct placement restorations, fixed and removable prosthodontics and oral surgery. The PPE items used before and during the COVID-19 pandemic were also included.
Results: Routine 'surgery set up' generic items present a significant proportion of SUP plastic waste as these are used in every instance of patient treatment. An average of twenty-one (n = 21) SUP plastic waste items are used for every procedure with a mean mass of 354 g per procedure (including set up and clean up). The use of PPE increased from 14 items (pre-COVID -19) to 19 items during the pandemic. SUP items are constructed from a single plastic or from multiple plastics forming compound structures (heteropolymers); with an approximate 50:50 distribution.
Conclusions: The dental profession, at the point of care, uses a high volume of single use plastic that becomes clinical waste. The use of personal protective equipment (PPE) significantly increased during the COVID 19 pandemic and this accounts for the single greatest contribution of single use plastic, as this is used for every clinical procedure.
Clinical Significance: Manufacturers, distributors and oral healthcare providers have an opportunity to consider and implement approaches that include effective waste management with reduction, recovery and recycling at its core, towards transforming oral healthcare to a circular plastics economy.
