A New Antibiotic Prophylaxis Regimen to Prevent Bacteremia Following Dental Procedures

Summary

The aim of this study is to evaluate the efficacy of prophylactic dosage with amoxicillin (AMX), amoxicillin-clavulanate (AMX-CLV), and a combination of amoxicillin-clavulanate and a chlorhexidine mouthwash (AMX-CLV-CHX) in the prevention of bacteremia following dental extractions. The study hypothesis is that an antimicrobial regimen with amoxicillin-clavulanate will show higher effectiveness in reducing the prevalence and duration of bacteremia following dental extractions, than that achieved with the classical amoxicillin regimen.
