Evaluation of the C-reactive protein serum levels in periodontitis patients with or without atherosclerosis

Background : Several studies suggested an association between periodontal disease and cardiovascular disease (CVD). C- reactive protein is elevated in periodontitis patients and has been found to be a predictor of increased risk for cardiovascular disease. Since, CRP is known to play a role in pathogenesis of atherosclerosis, the present study was undertaken to evaluate the serum levels of CRP in periodontitis patients with or without atherosclerosis. Materials and Methods : A total of 45 patients, 15 chronic periodontitis patients with atherosclerosis (Group A), 15 chronic periodontitis patients with no history of any systemic disease (Group B), and 15 clinically healthy individuals with no history of periodontal or systemic disease (Group C) within age range of 30 to 55 years were selected for the study. PI, PBI, PPD, CAL and radiographic marginal alveolar bone level were assessed in all the three groups. CRP levels were assessed with ′Turbi-latex′ kit using turbidimetric analysis. Results : The mean CAL recorded was 4.9mm in group A, 4.6mm in group B and 1.9 mm in group C. The mean radiographic marginal bone level was 45 to 50% in group A, 45 to 50% in group B and 90 to 95% in group C. Mean serum C-reactive protein level was significantly higher in group A (8.9 mg/l), as compared to group B (4.9 mg/l) as well as group C (0.9 mg/l). Conclusion : Within the limits of this study it was concluded that periodontitis may add to the inflammatory burden of the individual and may result in increased risk of atherosclerosis based on serum C-reactive protein concentrations.
