Objectives: Serum C‐reactive protein (CRP) has been shown to be a risk predictor for cardiovascular disease. Periodontal treatment reduces elevated CRP levels. The aim of this pilot investigation was to evaluate if dental implants placed after extractions in patients with end‐stage periodontitis affect the serum CRP levels. Material and methods: Serum CRP levels in 10 subjects with end‐stage periodontitis were measured prior to tooth extraction and placement of dental implants, and at 3‐month intervals for a year post‐operatively. Univariate repeated measures analysis of variance was used to estimate and test the changes in CRP levels over time. Results: Mean CRP levels decreased significantly following tooth extraction and replacement with dental implants from 3.45 to 1.55 mg/dl after 12 months (P<0.01). Six‐, 9‐, and 12‐month post‐implant placement mean CRP values were statistically significantly different from the mean pre‐operative CRP value (P<0.01). Conclusions: The pilot data suggest that extraction of advanced periodontally involved teeth and their replacement with dental implants lead to a decrease in CRP levels, and dental implant placement does not change the lowered CRP levels over a 12‐month period.
