All participants underwent a physical and oral examination, as well as blood sampling. Using panoramic radiography, root filled teeth, primary apical periodontitis, and secondary apical periodontitis were assessed by three independent observers. Blood samples were analysed with enzyme\u2010linked immunosorbent assay method for the following inflammatory markers: interleukin\u20101\u03b2 (IL\u20101\u03b2), IL\u20102, IL\u20106, IL\u20108, IL\u201012p70, tumour necrosis factor\u2010\u03b1, and high\u2010sensitivity C\u2010reactive protein (hsCRP). Additionally, white blood cell count and plasma\u2010fibrinogen were analysed.

After adjusting for confounders, root filled teeth remained associated with higher levels of fibrinogen, but lower levels of IL\u20101\u03b2, IL\u20102, IL\u20106, and IL\u201012p70.
