Environmental Impact of Dental Waste: A Survey-based Analysis of Waste Segregation and Recycling Practices in Dental Clinics.

AIM

The aim of this study was to assess biomedical waste management practices in dental clinics and explore the sustainability of strategies employed to minimize environmental impact while ensuring public health safety.

MATERIALS AND METHODS

A cross-sectional descriptive study was conducted among dental professionals in Tunisia from March 3, 2023, to March 10, 2024. A total of 50 clinics participated in the study. Data were collected using a survey questionnaire consisting of 30 questions, which were divided into three sections: Knowledge (10 questions), attitudes (10 questions), and practices (10 questions). The survey was conducted in person and was complemented by an observation checklist during waste audits in selected dental clinics. The data were recorded and statistically analyzed using the statistical software SPSS, version 20.0.

RESULTS

The study involved 120 dental professionals across 50 clinics. The results revealed that 68% of the participants demonstrated basic awareness of waste segregation, but only 42% followed consistent waste management protocols. The study identified challenges in sustainable practices, including limited training (only 30% of the participants had received formal waste management training) and insufficient infrastructure (44% of clinics lacked proper segregation bins). Environmental concerns were raised regarding incineration practices, with 50% of clinics continuing to use this method despite its environmental impact.

CONCLUSION

This study provides an overview of biomedical waste management practices in dental clinics, revealing variations in awareness, implementation, and available resources.

CLINICAL SIGNIFICANCE

These findings are crucial for policymakers and educators working to promote sustainable biomedical waste management in dental settings. By addressing knowledge gaps and implementing eco-friendly practices, the dental sector can reduce its environmental footprint while maintaining high public health standards.
