In the last 15-20 years the association between periodontitis and cardiovascular diseases has received greater attention. Clinical evidence also suggests that periodontitis is associated with a systemic host response and with a low-grade inflammatory state, as assessed by raised serum levels of CRP and endothelial dysfunction. This is a perturbation of the normal function of the endothelial cells that are responsible for a normal vascular function (dilatation, constriction). The objective of this review was to systematically appraise the available evidence on the effect of periodontal therapy on systemic biomarkers related to cardiovascular risk. An electronic search was conducted using MEDLINE via PubMed to identify published literature. The electronic search identified 836 references, of which 643 were considered irrelevant for this review. Full texts of 183 possible relevant articles were assessed, with exclusion of 174. Nine studies were included in the review. The overall effect of periodontal therapy was associated with a reduction in CRP of 0.50 mg/ml (95% CI 0.15, 0.85) (P=0.005). In conclusion, this review supports the hypothesis of an association between periodontitis and systemic inflammation. Further research is needed on the possible impact of periodontitis on cardiovascular disease events.
