An Oral Amoxicillin-Clavulanate Regimen to Prevent Bacteremia Following Dental Procedures

Summary

Although controversy exists regarding the efficacy of antibiotic prophylaxis for patients at risk of infective endocarditis, expert committees continue to publish recommendations for antibiotic prophylactic regimens. Recently, the investigators have evaluated the efficacy of the intravenous administration of 1000/200 mg of amoxicillin/clavulanate for the prevention of bacteraemia following dental extractions. The results of this study suggest that is highly effective, and that it might be considered a first-line choice for patients at high-risk for infective endocarditis who undergo dental procedures and for whom antimicrobial prophylaxis is recommended. This new project aims to evaluate the effectiveness of oral amoxicillin/clavulanate in preventing post-dental extraction bloodstream infection.
