Serum and Saliva Sirtuin 6, Lipoxin A4, Caspase8 Levels in Correlation With Periodontal Status in Severe Periodontitis

Istanbul Medipol University Hospital40 enrolled

Overview

It has been stated that Sirtuin-6 (SIRT6) play a important role in regulation of inflammation, energy metabolism, homeostasis and apoptosis, and SIRT6 may be assosiciated with many diseases. The aim of this study was to evaluate saliva and serum SIRT6, Lipoxin A4 (LXA4) and Caspase-8 (CASP8) levels in correlation with periodontal clinical status in patients with periodontitis and healthy subjects

20 patients with Stage III Grade B periodontitis (P) and 20 periodontally healthy individuals (control;C) were included in this study. Clinical periodontal parameters were measured. Saliva and serum levels of SIRT6, LXA4 and CASP8 were analyzed by enzyme-linked immunosorbent assay.

Interventions

Saliva and serum samplingOTHER

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 (MFD) from each participant. Saliva and serum were then stored at -80 °C until analysis.

Outcomes

Primary Outcomes

Pocket probing depth

Measurement of the depth of a sulcus or periodontal pocket determined by measuring distance from a gingival margin to the base of the sulcus or pocket with a calibrated periodontal probe.

Time frame: 6 months

Clinical attachment level

Clinical attachment level (or loss, CAL) is a more accurate indicator of the periodontal support around a tooth than probing depth alone. CAL is measured from a fixed point on the tooth that does not change, the CEJ. To calculate CAL, two measurements are needed: distance from the gingival margin to the CEJ and probing depth. In recession: probing depth (+) gingival margin to the CEJ (add). In tissue overgrowth: probing depth (-) gingival margin to the CEJ (subtract)

Time frame: 6 months

Bleeding on probing

referring to bleeding that is induced by gentle manipulation of the tissue at the depth of the gingival sulcus, or interface between the gingiva and a tooth.

Time frame: 6 months

Secondary Outcomes

Saliva and serum samples processing and analyses

Saliva and serum samples obtained for each patient were used for cytokine analysis. Prepared samples were analyzed for Lipoxin A4 (LXA4), Caspase 8 (CASP8) and Sirtuin-6 (SIRT6) using commercial ELISA kits (Elabscience, Houston, Texas, USA and Bioaasay Technology Laboratory (BT-Lab), Shanghai, China, respectively) according to the manufacturer's instructions.

Time frame: 2 months
