Objectives: The study aimed to assess the knowledge and practice of biomedical waste (BMW) management among dental practitioners in India during the coronavirus disease-2019 (COVID-19) pandemic era. Materials and methods: This descriptive, cross-sectional study was conducted via a web-based questionnaire survey done among 1,500 dentists across the country, and responses were collected between the months of May 2020 to June 2020. The use of descriptive statistics such as percentage analysis and frequency analysis of the survey respondents was done to describe the data. The Chi-square test was used to detect any correlation between the dentists’ responses concerning their gender and level of education and age. Variables with p < 0.05 were considered statistically significant. Results: The study engaged a total of 1,093 responses out of the 1,500 invited dentists, forming a response rate of 72.86%. Among these were 69.9% female and 30.1% male dentists. A 100% correct response was observed with the questions on the source of infection of COVID-19, frequency of disinfection of the dental chair, and cross-infection related to the disposal of BMW. The questions regarding the practice of donning off and disposing of personal protective equipment (PPE) were mostly incorrect with a percentage of 16.1 and 26.9%, respectively. The association between practice score and knowledge score concerning either gender was not significant (p > 0.05) whereas, the association with the level of education and age was found to be statistically significant (p < 0.05). Conclusion: The dentists in India were well informed of the hazardous waste generated in hospitals and clinics and were aware that it should be disposed off properly, especially in times of COVID-19. However, they lacked proper knowledge of the guidelines for disposing of specific types of waste during this pandemic.
