Feasibility and applicability of sustainable dental practice amongst dental practitioners in Delhi India

To assess the feasibility, and applicability of sustainable dentistry among practicing dentists and to identify barriers limiting the implementation of FDI-approved sustainable dental practices. A cross-sectional, questionnaire-based study was conducted among 3000 dental practitioners registered with the Indian Dental Association, of which 479 valid responses were received. A validated close-ended self-administered questionnaire assessed awareness and practices related to multiple domains of sustainable dentistry based on the FDI sustainability framework. Statistical analysis was performed using non-parametric tests. Focus group discussions (FGDs) were conducted to explore barriers and recommend practical solutions. Of the 479 respondents, 57% were female, and over 70% were younger than 40 years. Nearly 70% reported familiarity with FDI’s sustainability model and expressed willingness to adapt sustainable practices. Domain-wise analysis demonstrated variable adoption of sustainability-related practices, with relatively higher compliance in preventive dentistry and biomedical waste management and comparatively lower compliance in operative sustainability practices, digital workflow adoption, waterline monitoring and reduction of single-use plastics. Preventive care was emphasized by 95%, but gaps were identified in operative and integrated care practices, particularly in adopting digital impressions and reducing single-use plastics, mainly due to financial constraints and patient expectations. Older age and more years of practice were significantly associated with better sustainability domain scores( p < 0.05). Questions on Ownership of care practiced through collaborative approach revealed that 78% of dentists, preferred same day appointment for similar consultations. FGDs highlighted the need for training, regulatory support, and cost-effective alternatives. Our study demonstrated considerable awareness regarding sustainable dentistry among practitioners; however, implementation varied substantially across different sustainability domains The commonly reported barriers associated with this finding were the lack of appropriate training and knowledge regarding sustainability, lack of resources and the lack of support by regulatory agencies like the National Dental Commission (NDC) and State dental councils, Ethics and Dental registration boards, Central and State Pollution Control Boards (CPCB & SPCB) in spreading awareness, providing subsidies, strengthening rules and regulations regarding sustainability. A multipronged strategy involving training, financial incentives, and stronger regulatory support is required to improve the implementation of sustainable dental practices in alignment with the FDI sustainability framework.
