Inclusive Design for Future Oral Health Scenarios; A lifespan design approach investigating mainstream and extreme oral health pathways I

口腔健康状况影响咀嚼和言语等基本功能，并显著影响身体和心理健康以及生活质量，尽管采取了预防措施，但龋齿和牙周病仍然存在，影响所有年龄组。生物，物理和社会因素，如年龄，健康状况和神经认知能力进一步影响牙科保健的可及性和质量。亚组如老年人，儿童，年轻人，神经多样性或身体残疾的人面临系统性的不平等和经验oral health officials.This research advances Critical Inclusive Design（CID）作为一种方法，这是高度相关的，目前的口腔健康政策和系统过渡到包容和公平，以人为本和预防保健。其目的是概念化和情境化CID在口腔健康，并设定其未来应用的战略研究和政策议程。CID在包容性设计的既定领域取得了进展，该领域以人类多样性设计为中心，寻求创造对所有用户，特别是那些历史上被边缘化或排斥的用户可访问和包容的产品，服务和系统。通过批判性地识别和参与系统外围的“极端”场景和背景，CID旨在促进整体理解并实现创新的系统过渡工作。在这样做的过程中，CID与更广泛的社会，文化和政治背景，塑造包容和排斥的经验，有意在系统和政策层面上运作，考虑权力动态，社会正义和系统性压迫等问题，并制定设计策略来挑战和破坏这些动态。研究方法包括三个不同的活动：（1）全面评估口腔健康景观的更广泛设计;（2）通过“极端”研究，将CID概念化和情境化;（3）共同定义CID主导的英格兰西北部口腔健康政策和研究议程。本研究综合运用系统地图绘制、多利益相关者调查、访谈、社区参与和生成性工作坊等方法，建立了CID在口腔健康中的应用网络，为建立基于CID原则的包容性和公平的口腔健康体系提供了概念框架、方法和未来议程。研究的主要成果包括：口腔健康设计的交互式证据图; CID的理论框架;口腔健康系统中“极端”的定义，维度和故事;英格兰西北部口腔健康CID的战略研究和政策议程。

Oral health status impacts basic functions like chewing and speech, and significantly influences physical and psychosocial well-being and quality of life, Despite preventive efforts, dental caries and periodontal disease persist, affecting all age groups. Biological, physical, and sociological factors such as age, health status, and neuro-cognitive ability further influence dental care access and quality. Subgroups like older adults, children, young adults, and neurodiverse or physically disabled individuals face systemic inequalities and experience oral health disparities.This research advances Critical Inclusive Design (CID) as an approach which is highly relevant to current oral health policy and systems transitions towards inclusion and equity, person-centred and preventive care. The aim is to conceptualise and contextualise CID in oral health and set a strategic research and policy agenda for its future application. CID advances on the established field of inclusive design, which centres on designing for human diversity, seeking to create products, services, and systems that are accessible and inclusive for all users, particularly those who have been historically marginalised or excluded. By critically identifying and engaging with 'extreme' scenarios and contexts at the periphery of a system, CID seeks to foster holistic understanding and enable innovative system transition efforts. In doing so, CID engages with the broader social, cultural, and political contexts that shape experiences of inclusion and exclusion, intentionally operating on a systems and policy level, considering issues such as power dynamics, social justice, and systemic oppression, and developing design strategies to challenge and disrupt these dynamics. The research methodology consists of three distinct activities: (1) comprehensive assessment of the wider design in oral health landscape; (2) conceptualisation and contextualisation of CID in oral health through a study of 'extremes'; (3) co-defining a CID-led agenda for oral health policy and research in North West England. A combination of methods including systematic mapping, multi-stakeholder surveys, interviews, community engagement and generative workshops are employed, and CID in oral health network is established.This research contributes to advancing inclusive and equitable oral health systems through providing a conceptual framework, methods and future agenda grounded in CID principles. Key outcomes of the research include: an interactive evidence map of design in oral health; a theoretical framework of CID; definitions, dimensions and stories of 'extremes' in oral health systems; a strategic research and policy agenda for CID in oral health in North West England.
