Evaluation Of Bacteremia Following Periodontal Probing In Gingivitis And Periodontitis Patients.

Abstract

Background and aim : This study was done to determine whether bacteremia occurred before after periodontal probing in gingivitis and periodontitis affected patients and to identify the microorganisms present within positive blood cultures by aerobic culture. Materials and methods : 20 patients for each in gingivitis and periodontitis groups were selected, all with negative history of any systemic disorders. 5ml of venous blood was collected from every patient before and within 30 seconds of full mouth periodontal probing and simultaneously oral hygiene simplified, plaque index and number of sites that bleed on probing were recorded. The blood samples collected were transferred to the culture bottles containing brain heart infusion agar and brain heart infusion broth and incubated, samples signaled positive were then subjected to microbiological investigation. The positive samples were sub cultured on blood agar plates and the organisms were confirmed by gram staining method. Results : Probing caused bacteremia in 9 out of 20 periodontitis, and 3 out of 20 gingivitis patients. Streptococcus species was the most isolated organism in both the groups. Number of sites that bleed on probing, total probing depth and mean probing depth were significantly associated with bacteremia. Conclusion: Based on the findings of this study, it can be concluded that patients with untreated periodontitis were at greater risk of experiencing bacteremia due to periodontal probing.
