Effects of periodontal therapy on serum lipid profile and proinflammatory cytokines in patients with hyperlipidemia: a randomized controlled trial.
Keywords
Abstract
OBJECTIVE
The aim of this study was to evaluate whether periodontal treatment in patients with periodontitis and hyperlipidemia may have any influence on plasma lipids and pro-inflammatory cytokine levels.
METHODS
We randomly assigned 109 patients with hyperlipidemia and chronic periodontitis into group 1 (n = 55) and group 2 (n = 54). Patients in group 1 underwent a standard cycle of supragingival mechanical scaling and polishing. Patients in group 2 underwent the adjunctive full-mouth intensive removal of subgingival dental plaque biofilms with the use of scaling and root planning. Periodontal parameters, total cholesterol (TC), triglyceride (TRG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), tumor necrosis factor-alpha (TNF-α), interleukin(IL)-1β(IL-1β), and IL-6 were evaluated before treatment and 2 and 6 months after treatment.
RESULTS
Two and 6 months after treatment, TRG levels were significantly lower in group 2 than in group 1 (P < 0.05), and the levels of HDL-C were significantly higher (P < 0.05). Two and 6 months after therapy, the levels of TNF-α were significantly lower in group 2 than in group 1 (P < 0.05), as were the levels of IL-1β (P < 0.001) and IL-6 (P < 0.001).
CONCLUSIONS
Intensive periodontal treatment of participants with hyperlipidemia and chronic periodontitis improved serum lipid levels and decreased circulating pro-inflammatory cytokine levels.
CONCLUSIONS
This study showed that intensive treatment of periodontitis results in an improvement in serum lipid levels and a decrease in serum proinflammatory cytokine levels in patients with periodontitis and hyperlipidemia. These findings may contribute to present knowledge that periodontal therapy may be beneficial for individuals with hyperlipidemia.
