Abstract Objectives To assess the dentist's awareness about dental care waste management. To know the various methods of bio-medical waste disposal practiced by private dental practitioners in Chennai City. To assess the awareness of dentists regarding colour coding of biomedical wastes. Materials and Methods A cross sectional questionnaire study was conducted among 250 private dental practitioners selected by simple random sampling. A pretested questionnaire consisting of 28 close ended questions divided into two sections was used. Results Out of 250 participants 167(66.8%) were males and 83(33.2%) were females. About 14.8% of the dentists were not aware of the different categories of bio-medical waste generated in their clinic. About 28% of the dentists were not aware of the bio-medical waste management law in India and the same number (28%) were not aware of the colour coding for different types of biomedical wastes. Conclusion The present study indicates that the majorities of the dental practitioners were not aware of the different categories of biomedical waste and are not practicing the appropriate method of waste disposal. There is an urgent need for continuing dental education on dental care waste management for the dental practitioners.
