Analysis of Cell-free DNA (cfDNA) During Periodontitis

Recent emerging evidence has shown that circulating cell-free (cf) DNA are involved in in several epigenetic processes linked with periodontitis, coronary stenosis and systemic inflammation. The present study was aimed at assessing the impact of periodontitis on circulating cfDNA levels and evaluating possible confounders that influenced this association. Healthy controls (n=30) and subjects with CVD (n=31), periodontitis (n=31) and periodontitis+CVD (n=30) were enrolled. All subjects underwent regular periodontal examination and blood sampling. The analysis of the plasma cfDNA concentrations was performed using a dsDNA Assay Kit.
