The Need for a Sustainability Dentistry Guideline in Aotearoa New Zealand

Environmental sustainability has emerged as a significant issue in dental practices. Notably, the increased usage of personal protective equipment (PPE), primarily composed of single-use plastics (SUPs), poses a significant challenge to sustainable dentistry. This discussion paper explores the environmental implications of dental practices in Aotearoa New Zealand and the necessary interventions for transitioning towards sustainable dentistry, focusing on waste reduction. Despite the growing awareness of environmental impacts among oral health practitioners, substantial barriers persist. These include a perceived conflict between high-quality patient care, infection control, and environmental sustainability. A lack of education on managing resources and robust sustainable guidelines heightens the lack of sustainable actions. The paper explores potential plastic waste reduction strategies and sustainable practices such as digitisation, 3D printing, and the development of eco-friendly materials for personal protective equipment (PPE). It also highlights the need for preventive care, effective recycling of SUPs and PPE, and meaningful partnerships with dental product companies for innovative solutions. The paper advocates for creating sustainability dentistry guideline that align with the objectives of the Dental Council, Ministry of Health, and Ministry of Environment. Such guidelines would promote the integration of sustainability into daily operations of dental practices, using a plan-do-check-act (PDCA) model, and contribute towards a circular economy within the dental sector. The transition towards a more sustainable future for dentistry in New Zealand requires a multifaceted approach. This includes reevaluating traditional practices, increased research and collaboration, and formulating clear guidelines and sustainable waste management strategies
