Periodontitis Severity Grading Scale and C-Reactive Protein: A Possible Relation.

Background C-reactive protein (CRP) is the first acute-phase protein and is an exceptional investigative marker for local and systemic inflammation. The periodontitis severity grading scale (PSGS) indicates the extent of periodontal inflammation. Therefore, the aim of the study was to explore the correlation between the markers of systemic and periodontal inflammation as assessed by CRP and the PSGS in participants with periodontitis. Materials and methods The present study enrolled 85 systemically healthy participants with periodontitis. PSGS and CRP levels were measured in each participant. Descriptive and inferential statistics were applied for analysis. Results The PSGS scores ranged from 24 to 213, and the CRP levels ranged from 0.5 to 3.23 mg/l. This shows a positive correlation between the periodontal scale and CRP. A nonsignificant (p-value > 0.05) correlation exists between age and CRP score, and a significant association was seen between gender and severity of periodontitis with p-value < 0.02. A highly significant association between gender and CRP score was found with p-value < 0.001. Conclusion The level of serum CRP dramatically increased with the severity of periodontitis. The results of this study point to a highly significant correlation between markers of systemic and periodontal inflammation, as well as a strength of association between the two markers.
