Comparison and correlation of the factors affecting prevalence, intensity and nature of bacteremia during pre-operative, intra-operative and posto-operative period of trans-alveolar extraction of impacted mandibular third molar - An original research

Abstract

Background: This study is done to compare and correlate the factors that would affect the prevalence, intensity, nature of bacteremia during pre-operative, intra-operative and aftermath trans-alveolar extraction of impacted mandibular third molar. Aim: The aim of this study is to study the prevalence, nature, and intensity of bacteremia among the patients with no antibiotics administered prior to trans-alveolar extraction, with and with-out periapical and periodontal infections. Materials and methods: A prospective clinical study and microbiological assessment on blood culture was conducted at Department of oral and maxillo-facial surgery in 50 patients who underwent surgical removal of im- pacted mandibular third molar teeth. Immunocompro- mised patients, patients having temperature greater than 1000 F, bleeding disorders, patients on recent antibiotic medications were excluded from the study. Results: On comparison of the pre-operative, intra- operative and post-operative intensity values, the intensity of bacteremia was significantly greater at the intra operative and post-extraction time than at the pre-extraction time. Conclusion: We conclude that the incidence, prevalence and the intensity of bacteremia during trans-alveolar ex- traction is more common in older patients and periodon- titis is more prevalent in patients with poor oral hygiene which in turn contributes to the intensity of bacteremia associated with trans-alveolar extraction of third molar. From this study, it is found that, the occurrence of bacteremia is increased with duration of the surgery, as in- cidence of bacteremia was high when the surgery lasted more than 35 minutes in general.
