Romandini M, et al. - Experts conducted a cross-sectional study to see if periodontitis had any relationship to platelet count in a representative sample of the South Korea population. Findings suggested an independent association of periodontitis, especially when severe, with a considerable increase in platelet count which, at least in part, is explained by an increase in the systemic inflammation. In subjects over 60 years old, females, non-smokers and those with normal HDL blood levels, the association between severe periodontitis and platelet was emphasized.
