Transient bacteraemia is a known risk factor following oral surgery and invasive dental procedure. The most commonly isolated aerobic bacteria in postoperative bacteraemia are Streptococcus Viridans. However, other periodontal pathogenic anaerobic bacteria are found in up
to 64% in blood cultures (mixed bacteria or anaerobic bacteria alone). Dental pathogenic bacteria do not appear to be covered by standard amoxicillin or clindamycin prophylactic regimens.
A personal history of exposure to dental pathogenic bacteria may have an impact on the patient’s global health, because of classical local or systemic infectious complications. We believe that the use of amoxicillin/clavulanic acid is the most appropriate option for prophylaxis of all infectious risks associated with bacteraemia of oral origin, due to its broader cover of dental pathogenic bacteria and its pharmacokinetic profile.
