Pattern of bacteraemia after non-surgical extraction of tooth
2007
Objective: The objective of this study was to assess the pattern of bacteraemia after non surgical extraction of teeth. Methods: This prospective descriptive study was conducted at an out-patient setting at Karachi Medical and Dental College, Dental Hospital Karachi, over a period of six months (January 2007 to June 2007) on fif ty p atients. A pre designed performa was used to collect the relevant information from the patients. All cases of bacteremia (diagnosed on culture media) after non-surgical extraction of tooth/ teeth were included in the study. Total seven culture samples were taken from each patient pre and post extraction. Results: Thirty-four (68%) patients were male and sixteen (32%) were female. Mean age of patients was 32.14 ± 11 years. The commonest reason for tooth extraction was dental caries .The preextraction intravenous blood culture was negative in all fifty patients. The post extraction intravenous culture after one minute was negative in 60% of patients, after five minutes it was negative in 18% of p atients. After fifteen minutes post extraction, 99% of blood cultures were positive for bacterial growth, while 56% of blood cultures were negative for any bacterial growth after thirty minutes. Peptostreptococci and Streptococcus viridians species were the commonest bacterial isolates. Conclusion: Highest level of bacteraemia occurred after fifteen minutes of non-surgical tooth extraction. Peptostreptococci and Streptococcus species were found to be the commonest isolates.
