Assessment of transient bacteremia following various oral and dental interventions


The incidence of bacteremia following various dental interventions of 280 selected patients were studied using blood culture technique with aerobic and anaerobic cultivation. The incidence of bacteremia after multiple teeth extraction was higher (51.72%) than those single tooth extraction (44%). The incidence of bacteremia after local anaesthetic injection differs according to the type of injections significantly. In scaling and root planning the use of local prophylactic solution reduced the incidence of bacteremia from 37.7% to 13.9%. Poor oral hygiene had an effect on incidence of bacteremia at different dental interventions. The role of sex and age in bacteremia was variable. Aerobic bacteria were more than anaerobic and the most common bacteria isolated were Streptococcus viridans (30.5%) and Staphylococcus aureus (19.7%).
