Abstract:

AIM: To assess the effect of periodontal therapy (PT) on cardiovascular blood biomarkers. MATERIALS AND METHODS: This single-blind, parallel-design, randomized controlled trial included patients with stable coronary artery disease and periodontitis. The test group (TG) received non-surgical PT, whereas the control group (CG) received one session of plaque removal. Plasma levels of C-reactive protein (CRP), glycated haemoglobin, lipids and cytokines (IL-1beta, IL-6, IL-8, IL-10, IFN-gamma and TNF-alpha) were measured at baseline and after 3 months. RESULTS: Eighty-two patients (74.4% women, mean age 59.6 years) were analysed. TG had significantly better periodontal parameters than CG after 3 months, but no significant differences in blood markers were observed between them. In a post hoc subgroup analysis in patients with baseline CRP <3 mg/L, a significant increase in CRP was observed in CG (1.44 +/- 0.82 mg/L to 4.35 +/- 7.85 mg/L, p = 0.01), whereas CRP remained unchanged in TG (1.40 +/- 0.96 mg/L to 1.33 +/- 1.26 mg/L, p = 0.85), resulting in a significant difference between groups at 3 months. In patients with CRP >/=3 mg/L, a significant reduction in CRP was observed only in TG (11.3 +/- 12.8 mg/L to 5.7 +/- 4.1 mg/L, p = 0.04). Levels of IL-6 and IL-8 were significantly lower in TG than CG at 3 months. CONCLUSIONS: PT leads to lower levels of CRP, IL-6 and IL-8 in cardiovascular patients with high CRP levels.
