The environmental impact of community caries prevention - part 2: toothbrushing programmes

Introduction Community-level caries prevention programmes includes supervised toothbrushing in schools and the provision of toothbrushes and toothpaste. The environmental impact of these interventions is an important factor to consider when commissioning these services. Materials and methods A comparative life cycle assessment (LCA) was conducted to quantify the environmental impact of a five-year-old child receiving one of two toothbrushing programmes over a one-year period; supervised toothbrushing in school, or the provision of toothbrushes and toothpaste. Results Supervised toothbrushing had a lower environmental impact than provision of toothbrushes and toothpaste in all 16 impact categories measured. The water use needed for children to brush their teeth was the greatest contributing factor to the provision of toothbrushes and toothpaste, accounting for an average of 48.65% of the impact results. Discussion All community-level caries prevention programmes have an associated environmental cost. LCA is one way to quantify the environmental impact of healthcare services and can be used along with cost and clinical effectives data to inform public healthcare policy. Organisations responsible for these programmes could use the results of this study to consider ways to reduce the environmental impact of their services.
