Overall 97.9% of the practitioners were aware of the waste management policy, 47.9 % were handing over the waste to municipal garbage collectors, 54.2% felt that there was a lack of awareness regarding the existing health care waste management services within the city, 44.8% contacted the certified waste carrier services, 42.7% discarded blood soaked swabs and gauze in specific colour coded plastics during disposal. Conclusion: From the study it was found that a large number of practitioners are aware of the legislation policy but have failed to contact and register their clinic under certified waste management services of the city. Lack of professional training has been a major cause for the same. Hence there is a need to educate the dental practitioners regarding proper practice measures.
