Bacteremia and intraoral suture removal: can an antimicrobial rinse help?

Recent studies have shown that bacteremia can result from the removal of intraoral sutures. The authors found that preprocedural use of an antimicrobial oral rinse (0.12 percent chlorhexidine) did not significantly reduce the incidence of bacteremia when compared with no rinse at all. Similarly, a significant relationship between bleeding and bacteremia was not apparent. Most of the positive cultures yielded low colony counts. The results support the rationale for the American Heart Association's 1997 recommendations for use of antibiotic prophylaxis to prevent bacteremia, as well as the importance of good oral hygiene in prevention efforts.
