Infective Endocarditis: Etiology, Epidemiology and Current Recommendations for the Dental Practitioner

Infective endocarditis (IE) remains one of the most serious diseases with a high morbidity and mortality rate. Although the condition is more common in the medical field in a hospital setting, dentists must have a thorough understanding of the overall pathogenesis, epidemiology, risk factors and signs and symptoms that may be present in their patient population. In 2021, the American Heart Association (AHA) updated its guidelines on IE, emphasizing the specific criteria that put a patient at risk of acquiring IE, specific dental procedures that can increase the risk of IE by inducing bacteremia and an antibiotic prophylaxis regimen to act as a preventive measure if needed. This literature review gives the dental practitioner a general overview of the AHA guidelines as well as information on prevention in their at-risk patients and the need to emphasize a well-structured, consistent daily oral hygiene routine.
