Assessment of the effect of periodontal treatment in patients with coronary artery disease : A pilot survey.

Background: Periodontitis is a chronic inflammatory condition believed to cause a low but long lasting systemic inflammatory reaction which in turn contributes to the development of atherosclerosis. Recent data suggests that around 40% cases of coronary artery disease remain unaccounted despite the identification of the classical risk factors.

Objectives: To evaluate the efficacy of non surgical periodontal therapy on the levels of serum inflammatory markers in subjects with chronic periodontitis and known coronary artery disease.

Materials And Methods: Twenty subjects with known coronary artery disease (CAD) were recruited from the Department of Cardiology, CSM Medical University, Lucknow, India, for this study. Periodontal disease was measured through the clinical parameters bleeding on probing (BOP) and probing depth (PD). All subjects received non surgical periodontal therapy that included oral hygiene instructions and meticulous scaling and root planing. Systemic levels of inflammatory markers such as high-sensitivity C reactive proteins (hsCRP), tumor necrosis factor-α (TNF-α), and white blood cell (WBC) counts were measured prior to and 1 month after periodontal therapy.

Results: Subjects experienced significant reductions in bleeding on probing (BOP) and probing depth (PD), indicating improvement in overall periodontal health. In all subjects, high-sensitivity C reactive proteins (hsCRP), and WBC counts were reduced significantly,; however, tumor necrosis factor-α (TNF-α) levels showed no statistically significant reduction.

Conclusion: In this study, periodontal treatment resulted in a significant decrease in bleeding on probing (BOP) and probing depth (PD), and this treatment lowered the serum inflammatory markers (hsCRP and WBC counts) in patients with coronary artery disease. This may result in a decreased risk for coronary artery disease in the periodontally treated patients.
