Annexin Levels of Periodontal Inflammatory Regulation

Saliva were collected to analyze the selected markers as unstimulated samples during the early hours of the day. The saliva was centrifuged and then transferred into Eppendorf tubes. Venous puncture was performed after saliva collection and 10 mL of blood samples were collected by qualified staff from each participant. Gingival crevicular fluid (GCF) samples were taken from the vestibular, mesial, and distal surfaces of a single-rooted tooth with standard paper strips (Periopaper, Oraflow Inc., Plainview, NY, USA). Saliva, GCF and serum were then stored at -80 °C until analysis.
