Environmental sustainability: measuring and embedding sustainable practice into the dental practice

Exploring environmental sustainability in dentistry among students and educators in the United Arab Emirates: a cross-sectional survey

OBJECTIVES

Creating environmentally sustainable healthcare culture within the dental field requires embedding the content in the dental curriculum at the undergraduate level. This study aimed to explore the current awareness and drivers among dental students and educators regarding environmentally sustainable dentistry (ESD) in the United Arab Emirates (UAE) and identify barriers and enablers to embrace it.

METHODS

A cross-sectional survey using online questionnaires was carried out in six undergraduate dental education institutes within the UAE. Data analysis included descriptive statistics.

RESULTS

In total 153 students and 53 educators participated in the survey. Most students and educators were not aware of any ESD content in their curricula. However, the majority of educators were familiar with the concept of ESD, while students were mostly unfamiliar or slightly familiar. Nonetheless, students largely agreed on its importance and their interest in learning it, as they viewed it relevant to their future practice. Educators agreed that the dental profession has a responsibility to be environmentally friendly and expressed their desire in introducing ESD content into the curricula. Several barriers were reported such as lack of knowledge, curricula space, educational resources, and time. Meanwhile, enablers included providing ESD capacity building, training and resources.

CONCLUSIONS

There was no explicit presence of ESD content in the dental curricula in the UAE. Despite the lack of adequate awareness on this topic among educators and more so among students, they both had positive views towards incorporating ESD into dental curricula. Overall, this study highlighted the importance of promoting ESD in dental programs.

CLINICAL SIGNIFICANCE

ESD is gradually becoming a critical aspect of modern oral healthcare system. It has been mandated in the dental curricula in several regions globally. Embedding ESD in the UAE dental curricula would have several benefits for the environment as well as the future of the dental profession in the region. The clinical significance includes, but not limited to, improved treatment outcomes; patients, students and staff health and well-being; reduced health risks, and cost savings.

Curriculum Content for Environmental Sustainability in Dentistry

OBJECTIVES

(i) Identify suitable strategies and opportunities to embed Environmental Sustainability (ES) within an existing Oral Health Professional (OHP) curriculum through a series of focus groups with students and academic staff and (ii) Create high-level evidence-based and subject-specific ES content through an approach grounded in evidence and collaboration with key stakeholders in OHP education.

METHODS

Focus groups were used to explore academic staff and student views on appropriate teaching and assessment methods for ES. Content statements were developed from an extensive literature search, mapped to curriculum subjects, and validated through consultation with students, discipline-experts and education-experts.

RESULTS

Five themes were identified from the focus groups: Environmental Sustainability transcends all disciplines of dentistry and oral healthcare; Baseline knowledge transmission with relevant practical application; Viewing and modifying existing teaching and assessment events through a different lens; Normalising the topic of Environmental Sustainability to support attitude and behaviour change and Safeguarding against misinformation and disinformation. Forty-four content statements were developed and mapped to nineteen curriculum subjects.

CONCLUSIONS

This study identifies for the first time a comprehensive strategy for the inclusion and delivery of ES (method and content) in the curriculum. A novel method to define and map curriculum content has been explored and validated using a range of complementary methodologies. A comprehensive and robust list of evidence-based and subject-specific educational content statements have been defined in the field of Environmental Sustainability in dentistry and oral healthcare.

CLINICAL SIGNIFICANCE

Oral healthcare has a significant environmental impact, the key to all mitigation strategies is by educating the profession at all levels.

Discussing the environmental impact of dental-associated travel - how do we build from the current COVID-19 crisis towards a more sustainable future within dentistry?

Dentistry is a highly energy- and resource-intensive field and consequently has a significant environmental impact. In 2013-2014, total greenhouse gas emissions of NHS dental services in England measured 675 kilotonnes of carbon dioxide equivalents, with 64.5% related to travel, 19% from procurement and 15.3% from energy use. There is currently an absence of comprehensive standards or guidelines for sustainable dentistry. Instead, sustainable initiatives have been at a small scale and are adopted voluntarily by groups or professionals as an ethical duty or practical requirement. However, a recent study showed that there seems to be increasing interest from dental teams in how to become more sustainable. This opinion article focuses on how the dental profession can ensure a sustainable recovery as England emerges from the COVID-19 crisis, with an emphasis on improving environmental sustainability related to travel within the dental healthcare system. Reducing dental-associated travel can include changing mode of transport, combining family appointments, appropriate scheduling of dental examinations, preventive dentistry and the use of information technology.

Sustainability is a marketable commodity which can improve a practice's reputation, a statement supported by commercial studies.

There are numerous suggestions for change to reduce the environmental impact of dental services, including the implementation of information technology where appropriate.

Preventative dentistry is the most sustainable way to ensure optimal, accessible and affordable oral health for patients, with minimal impact on the environment.

Characteristics of wastewater originating from dental practices using predominantly mercury-free dental materials

Dental materials are currently undergoing a revolution. Mercury use, including traditional amalgam (mercury-containing) material used in dental fillings, is now being widely regulated under the Minamata convention, and dental amalgam is currently being replaced by resin formulations in dentistry. These resin-based materials can be tuned to offer varying material properties by incorporation of a range of nano- and micro-particle based 'fillers' for different dental properties and applications. However, these innovations may have a concomitant effect on the waste streams associated with common dental applications, in particular the potential for higher concentrations of novel micro- and nanomaterials within wastewater streams, and a potential route for novel nanomaterials into the wider Environment. These new materials may also mean that wastewater filtering apparatus commonly deployed at present, such as amalgam separators, may be less efficient or insufficient to capture these new filler materials in dental facility wastewater. In this work, we analyse dental wastewater streams from three dental facilities in Ireland with differing amalgam separators in place. The potential overall toxicity, particulate load and physicochemical properties are analysed. The overall risk posed by these new materials is also discussed.

Digital Entrepreneurship via Sustainable Online Communication of Dentistry Profession, Oradea, Romania: A Longitudinal Analysis

Dentistry is an entrepreneurially oriented public interest profession that must maintain a balance between professional specificity and business sustainability. Communicating with patients is vital in a competitive system, and the dentist needs to use handy resources such as websites and social media. The aim of this research is (a) to examine whether websites and social networks are a digital entrepreneurship tool used in the dentistry profession in Oradea, a city in full economic development in Romania, to promote the profession nationally and internationally, (b) to compare the changes made using digital tools in the period between 2018–2021 for all licensed dentists in the mentioned city (between 430–450 people, depending on the stage of analysis) using the content analysis method and (c) to identify how the lockdown period imposed by the emergence of the COVID-19 pandemic influenced not only the sustainability of the medical services provided to the population but also the communication practices of the dental offices. The results of examining the dentist’s online presence reveal that there is an interest among practitioners to grow their business sustainably through a digital presence that is increasingly relevant to them and their clients, but the potential remains under-exploited.

Embedding environmental sustainability within the modern dental curriculum- Exploring current practice and developing a shared understanding

INTRODUCTION

Evidence concerning the interactions between human health and planetary health has grown extensively in recent years. In turn, the perceived importance of environmental sustainability within higher education is growing at a rapid rate. This paper provides a summary of key elements as they apply to dentistry, and provides an introduction to the reader of an early consensus of how sustainability could be included as part of the dental curriculum.

METHODS

The consensus opinion within this paper largely centres around discussion at the ADEE sustainability workshop at the annual conference in Berlin (August 2019). In order to help inform discussions at the workshop, a brief scoping questionnaire was circulated to potential participants regarding their understanding and current teaching practices in sustainability. An infographic was designed to help delegates remember the important elements of sustainable dentistry. Delegates discussed the concept of sustainability alongside the infographic, and how they could link these with the Graduating European Dentist (GED) curriculum.

RESULTS

The discussions within the workshop largely centred around 4 main themes: Disease prevention and health promotion, Patient education and empowerment, Lean service delivery and Preferential use of strategies with lower environmental impact.

DISCUSSION

It is apparent that there is a widespread need for teaching materials relating to environmental sustainability; this includes specific learning outcomes relating to the 4 educational domains of the Graduating European Dentist curriculum, and methods for teaching and assessing these outcomes.

CONCLUSION

This paper reports consensus on the first phase of a pan-European working group on Sustainability in dental education.

Drivers, opportunities and best practice for sustainability in dentistry: A scoping review

OBJECTIVE

To undertake a comprehensive scoping review of the literature to address the research question 'What is the current state of environmental sustainability in general dental practice?' To provide an effective baseline of data that will consider the drivers, opportunities and recommendations 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 second paper focusing on the opportunities, recommendations and best practice to develop and engage with sustainable practice.

CONCLUSIONS

Drivers, opportunities and recommendations for best practice to achieve environmentally sustainable goals in oral health care: The lack of public and professional awareness is the greatest driver to engage with a positive change of behaviour and attitudes. Awareness through education is key at all levels and this should be the bedrock of future strategies. Reduction in staff and patient commuter travel through a reduction of the incidence of preventable oral diseases, improved patient care logistics and IT. Reducing waste and increase recycling opportunities, especially for SUPs. Engagement with legislation and policy makers. Engagement with key stakeholders across the dental materials/products supply chain for the management of manufacturing, distribution, procurement, clinical use and waste management.

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.

Sustainability in Dentistry: A Multifaceted Approach Needed

This article provides an introduction to environmentally sustainable dentistry and offers perspectives on managing drivers to reduce carbon emissions and make dentistry more environmentally sustainable. A sustainable world must meet the needs of the present without compromising the ability of future generations to meet their own needs. Global commitment to sustainability and demands for a sustainable world are growing. Within dentistry, travel creates the highest carbon emissions and also contributes to human health damage. Internally, there are a number of ways to reduce impact by decreasing travel and energy use, as well as carefully considering the types of items purchased (and how they are disposed of). Larger dental organizations can influence their suppliers and industry by choosing to purchase from sustainable companies with environmentally friendly products. From an external driver perspective policy, guidance and research are essential. Governments need to reevaluate decontamination policy from an environmental perspective. Decontamination documents need revision to consider both planetary and public health. Dental organizations need to support dental teams in this area. Insurance providers and health care purchasers should review policies to influence the sustainability of dental providers. Sustainability education needs to be considered as part of the curriculum of undergraduate and postgraduate students. Guidance could also be developed for the dental industry to produce sustainable products. Research needs to be prioritized. Identifying hot spots or areas of high environmental contributions using other assessments such as life cycle analysis (LCA) would allow dentistry to identify products or practices that have a disproportionate adverse impact on the environment and might be prioritized for change. This should include an analysis of single-use instruments, chemicals, and products. Building research capacity by training students and creating virtual or physical centers for sustainability is essential. Financial support is needed for priority areas of research.

Environmentally sustainable dentistry: a brief introduction to sustainable concepts within the dental practice

This paper introduces clinicians to sustainability as it relates to dentistry. There are seven papers in the series. These include this introduction, followed by papers on energy, procurement, travel, waste, biodiversity and engagement and embedding sustainability into current dental practice. A sustainable world aims to ensure the basic needs and quality of life of everyone are met, now and for future generations. The current delivery of healthcare in the modern world is not sustainable due to rising financial costs, increasing demands and a high environmental burden. Dentists, like their medical counterparts, need to consider the General Dental Council (GDC) standards and the relationship between planetary health and human health within their practice. There is increasing awareness of the problems associated with global warming but a lack of knowledge on how to become more environmentally sustainable. There are also financial and reputational benefits to becoming more sustainable for practices. The carbon footprint is one proxy of sustainability and is closely related to expenditure. In 2014-2015, the carbon footprint of dentistry was calculated to be 675 kilotonnes carbon dioxide equivalents (CO2e) with 64.5% related to travel, 15.3% from energy and 19% from procurement. The GDC should consider incorporating sustainability education into the undergraduate framework in line with student demands and similar moves by the General Medical Council.

Facilitating Green Supply Chain in Dental Care through Kansei Healthscape of Positive Emotions

Dentistry is highly energy- and resource-intensive with a significant environmental impact. To consolidate green dentistry supply chains, delivering the care of highest quality that meets client value should not be neglected. This study emphasized the importance of client-centered healthscape design for facilitating a green dentistry supply chain. A client-centered healthscape design, which promotes clients' positive emotions and increases willingness to revisit the dentist, plays a critical role in realizing green dentistry supply chains in the long run. For this purpose, the relationship among dental healthscape design elements, client emotions, and revisit intentions was investigated using a Kansei engineering-based approach. The effects of dental healthscape elements on clients' positive emotions and the effects of positive emotions on clients' revisit intentions were holistically examined on the basis of the stimulus-organism-response model. Through this approach, 17 elements of design, ambience, and social interaction factors that comprise the dental healthscape and 20 Kansei words used to express clients' positive emotions regarding dental service were identified. A questionnaire survey was used to assess Kansei and revisit intention in healthscape scenarios, composed of varied design elements. Primary data were collected from 600 individuals from 2017 to 2018 throughout Taiwan. Partial least squares was applied to holistically analyze the effects of dental healthscape elements on clients' positive emotions and the effects of positive emotions on clients' revisit intention to generate a Kansei model for the dental healthscape. All 20 Kansei words had significant positive effects on the dental revisit intention of clients. The five positive emotions most associated with increased revisit intention were thoughtful, hopeful, tender, comfortable, and cozy. The Kansei model of the dental healthscape provides references for healthscape design that maintains positive client emotions during the dental service and results in high revisit intention. This approach can realize an emotion-centered design for dental healthscapes that promotes preventive dental care, early treatment, and effective use of medical resources, and consequently contributes to green dentistry supply chains.
