Background: The acute-phase response involves molecules including tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), and C-reactive protein (CRP). This study aimed to determine whether subgingival scaling resulted in rapid changes in plasma concentrations of these molecules. Methods: Twenty-three non-smoking adults with chronic periodontitis received subgingival scaling for 60 minutes. Venous blood samples were taken at 0, 15. 30, 60, and 120 minutes. TNF-α and IL-6 were assayed from all samples and CRP From the baseline and final samples. Lipopolysaccharide (LPS) was assayed at 0, 15, and 30 minutes using limulus lysate assay (LAL) and EndoCAb Ig assays. Results: LPS assays were suggestive of a transient low-grade bacteremia, but changes in LPS approaching significance (P = 0.061) were seen with LAL only. There was a significant increase in circulating TNF-α (P = 0.0387) and IL-6 (P <0.0001), and the degree of charge in TNF-α was correlated with the severity of periodontal breakdown (P = 0.001). There was also a significant correlation between levels of IL-6 and TNF-α (P <0.001). Conclusions: Chronic periodontitis patients undergoing an episode of subgingival scaling show a significant elevation in circulating TNF-α and IL-6. This may account for anecdotal reports of pyrexia following treatment and may be significant in terms of the relationship between periodontal disease, bacteremia, and cardiovascular disease.
