Overview

MicroRNAs are important regulators of the immune and inflammatory response to bacterial pathogens during periodontal disease.The aim of this study was to evaluate the possible miRNA type for Parkinson's in saliva of orally healthy individuals.

A total of 51 individuals, 35 systemically healthy and 16 with Parkinson's disease and both dental and periodontal health, were included in the study.Clinical periodontal parameters, DMFT data and salivary flow rates were recorded.Unstimulated saliva samples were taken from each participant and miRNA was evaluated by RT-qPCR method.ELISA method was used to measure TNF α values in collected saliva and serum samples.

Interventions

Saliva and SerumOTHER

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.Saliva and serum were then stored at -80 °C until analysis.

Saliva and SerumOTHER

ELISA method will be used to measure TNF-α values in collected saliva and serum samples.RT-qPCR based miRNA gene expression analyses will be performed with 2-step qRT-PCR Kits (Thermofisher Scientific, MA, USA).

Outcomes

Primary Outcomes

1. 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

2.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

3.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

4.Saliva and serum samples processing and analyses

Time frame: 1 month
