Özet:
Some dental procedures may initiate a bacteraemia. In certain compromised patients, this bacteraemia may lead to distant site infections, most notably infective endocarditis. Objective: This study aimed to investigate whether a detectable bacteraemia was produced during non-surgical root canal instrumentation. Methods: Thirty patients undergoing non-surgical root canal treatment were studied. Blood collection was undertaken pre-operatively, 5 minutes after access was gained to the root canal system and 5 minutes after the treatment was completed. In addition, a microbiological sample was collected from the root canal immediately after access was gained. The blood samples were cultured by two methods and the isolated aerobic and anaerobic organisms were identified by standard techniques. In addition, each blood sample was analysed by polymerase chain reaction (PCR). Where the same species of organism was identified in the root canal and the bloodstream, the isolates were typed by pulsed field gel electrophoresis (PFGE). Results: By conventional culturing, a detectable bacteraemia was present in 9 (30%) of 30 patients who had no positive preoperative control blood sample. In 7 (23.3%) of 30 patients, the same species of organism was identified in both the bloodstream and in the sample from the root canal system. In general, PCR gave lower detection rates, with 10 (11%) of 90 blood samples displaying bacterial DNA. PFGE revealed that two pairs of positive cultures investigated were genetically identical. Conclusions: Non- surgical root canal instrumentation is capable of invoking a detectable bacteraemia in the clinical setting.
