Aims and Objective The present survey was done to assess the knowledge, awareness, and practice of undergraduate students, postgraduate students, and practitioners about disposal of common biomedical wastes and materials used in dentistry regularly.

Materials and Methods The survey (23 questions) was conducted on 162 participants categorized as undergraduates (n = 54), postgraduates (n = 54), and practitioners (n = 54) to assess their knowledge, awareness, and practice.

Results When questioned whether they were aware of disposal of waste according to color categories, 69.8% were aware of it, 2.5% were not, and 27.8% were not sure of the color-coded categories. When subjected to statistical analysis, the data were found to be statistically significant (p = 0.017). Only 58% were aware that the number of categories of biomedical waste management is divided into four categories based on new regulations. There was statistical significance between the scores of undergraduates and practitioners (p = 0.046).

Conclusion There is a gap between knowledge and implementation of segregation of waste at source; certified carrier service should make sure all the wastes are segregated from the dental practitioner's premise with an update on dental materials segregation for dental clinics and laboratories. Frequent updates of biomedical management of waste rules should be performed by the certified carrier.
