Environmental impact of the supervised toothbrushing programme amongst children in Scotland

To understand the environmental impact of providing a nationwide supervised toothbrushing programme (Childsmile) for 5-year-old children in Scotland.

A life cycle assessment was conducted to assess the annual environmental effects of the supervised toothbrushing programme in early years childcare, as well as each dental procedure (dental restoration under local anaesthesia (LA), single tooth extraction under LA, and multiple teeth extraction under general anaesthesia) spanning from 2001/02 to 2009/10. The expected savings in annual carbon dioxide equivalent (CO2e) emissions for all combined dental treatments in subsequent years were calculated compared to those in 2001/02.

An overall decrease in CO2e emissions was evident in the Childsmile programme and across all dental procedures. The estimated reduction in emissions across all procedures varied from 102.5 tonnes in 2002/03 to 461.1 tonnes in 2009/10 when compared to 2001/02. Within three years, the expected emissions savings from all combined dental procedures surpassed the emissions generated by implementing the Childsmile programme.

Over time, there was a significant reduction in annual CO2e emissions for all combined dental treatments in children. In the eighth year of the Childsmile, emissions savings were more than 4.5 times greater than the emissions generated during its implementation.

The study highlights the importance of educating public by individual dentists about the environmental impact of caries prevention programmes and paediatric dental treatments as this may influence patient choice. It also encourages commissioners of community dental programmes to support the implementation of supervised toothbrushing programmes in early years childcare.
