The use of prophylactic antibiotics for the prevention of infective endocarditis following dental procedures has long been debated and there is still confusion regarding its efficacy. As a result, the prophylactic treatment varies considerably amongst different countries across the world and amongst different dental practitioners.


To evaluate the knowledge of dental staff regarding the guidelines for the prevention of infective endocarditis.


This was a cross sectional analytical study which included all staff members. A self administered questionnaire was used and responses were “graded” according to the American Heart Association (AHA) guidelines.


The response rate was 87% (N=39) and 97% reported to use the AHA guidelines; 66% reported their knowledge was based on previous training and scientific journals. Of those cardiac conditions and dental procedures which required prophylaxis; 47% and 65% chose the correct option, respectively. Penicillin was prescribed as the drug of choice by the majority of respondents.


Although almost all staff reported the use of the AHA guidelines, many were not following them. The study emphasizes the need for continuous education and evaluation of this critical aspect of dentistry.
