Aim: to assess Dentist Awareness of Basic life Support (BLS) among Dental colleges of Ghaziabad U.P India. Materials and Methods: A cross-sectional questionnaire survey was carried out in randomly selected 3 dental colleges out of 6, pursuing post-graduation courses in Ghaziabad. A questionnaire with 20 questions regarding the awareness and skills involved in BLS was used to assess the levels of awareness to BLS and its practical knowledge. The aspects on which the subjects were interrogated were about the abbreviation of BLS, AED and EMS (Emergency Medical Service), sequential steps in BLS, assessment and resuscitation techniques with regard to airway, breathing, circulation in unresponsive victims of different age groups, techniques regarding removal of foreign body obstruction, recognition of early signs of stroke and acute coronary syndrome Results: None among them had complete Knowledge of BLS. 248 out of 340(73%) had secured less than 50% marks. In the present study BDS faculty and postgraduates of dental sciences were same but MDS faculties were somewhat aware about BLS. On comparison MDS Faculty showed more awareness as compared to PG students and BDS faculty. Conclusions: It is also equally important that teachers, school children, public and all lay persons from the community be taught the facts of basic life support and first aid.
