Knowledge, attitudes, practices, and barriers regarding environmentally sustainable dentistry among dental faculty in the Delhi/National Capital Region of India

Objectives: To evaluate contemporary knowledge, attitude, practices (KAP) and challenges related to environmentally sustainable dentistry (ESD) among a diverse group of dental faculty working in the Delhi/National Capital Region region of India. Materials and Methods: A cross-sectional survey was conducted on 74 dental faculty members using a purposive snowball sampling method. The questionnaire was validated through pilot testing and expert review. Results: Most study participants were aware of essential environmental sustainability practices in their institutions, such as using energy-efficient appliances and digitalizing patient records. However, significant gaps remain in biowaste management practices. Very few institutions have installed amalgam separators in dental chairs, and 42% were unfamiliar with the life cycle analysis of dental products. Relying on personal vehicles for commuting contributes to carbon dioxide emissions, and the continued use of single-use plastics and disposable materials is the most common practices impacting the implementation of ESD among the study population. Conclusion: This study offers preliminary insights for developing and shaping ESD guidelines for Indian dentistry. It highlights the urgent need for eco-friendly innovations and calls on dental professionals to proactively reduce their carbon footprints, thereby setting a powerful example for patients and dental students.
