dsDNA yields extracted from single paper points. The dsDNA yields were quantified fluormetrically. Data represent 18 samples per health condition (periodontal healthy and periodontitis-affected sites) collected from six participants for each of the three kits, shown on a logarithmic scale. MN: NucleoSpin Tissue kit, MACHEREY‑NAGEL, ZB: ZymoBIOMICS DNA Miniprep kit, ZYMO RESEARCH, QB: DNeasy Blood & Tissue kit, QIAGEN. Significant differences (Wilcoxon signed-rank test) are indicated by an asterisk (*).
