Awareness and barriers to sustainability in dentistry: A scoping review

Objectives

(i) To undertake a comprehensive scoping review of the literature that addresses the research question ‘What is the current state of environmental sustainability in general dental practice?’ (ii) To provide an effective baseline of data that will consider general awareness, barriers and challenges for the implementation of sustainable practice.

Data & sources

The scoping review was conducted for all published literature in the English language that addresses this topic up to the 31st April 2021. The method of the PRISMA-ScR (PRISMA extension for Scoping Reviews) was followed. 128 papers included in this scoping review consisted of: Commentary [Letters, editorials, communication and opinion] (n = 39); Research (n = 60); Literature reviews (n = 25); Reports [Policy and legislation] (n = 4). Each included record was analysed for emerging themes that were further classified according to their general relevance. The scoping review is considered over two manuscripts, with this first paper focusing on awareness of the problem and barriers or challenges to the implementation of sustainable care.

Conclusions

Eight diverse but closely interlinked themes that influence the sustainability of oral health provision were identified: Environmental impacts (CO2e, air and water); Reduce, reuse, recycle and rethink; Policy and guidelines; Biomedical waste management; Plastics (SUPs); Procurement; Research & Education; Materials. Barriers to implementation were identified as: Lack of professional and public awareness; carbon emissions arising from patient and staff commute; challenges associated with the recovery and recycling of biomedical waste with a focus on SUPs; lack of knowledge and education into sustainable healthcare provision and; the challenges from the manufacturing, use and disposal of dental materials.
