You will receive 2 credit(s) of continuing education credit upon successful completion of this course. The purchase price of this course is $98.00


Course details the 2007 American Heart Association recommendations for prophylactic antibiotics for the prevention of infective endocarditis as they relate to dentistry, and includes prevention techniques, and basic info about heart conditions and antibiotics.

Learning Objectives:

Upon completion of this course, participants should be able to do the following:

  1. Describe the changes in AHA recommendations.
  2. Explain the reason for the changes in AHA recommendations.
  3. Discuss basic prevention techniques for Infective Endocarditis.
  4. Determine when it is reasonable to prescribe prophylactics.


This course updates the recommendations by the American Heart Association (AHA) for the prevention of infective endocarditis, which were last published in 1997, as they relate to dentistry.

A writing group appointed by the AHA for their expertise in prevention and treatment of infective endocarditis (IE) with liaison members representing the American Dental Association, the Infectious Diseases Society of America and the American Academy of Pediatrics reviewed input from national and international experts on IE. The recommendations in this document reflect analyses of relevant literature regarding procedure-related bacteremia and IE; in vitro susceptibility data of the most common microorganisms, which cause IE; results of prophylactic studies in animal models of experimental endocarditis; and retrospective and prospective studies of prevention of IE.
