Determination of Salivary Soluble Urokinase Plasminogen Activator Receptor (SuPAR), Hypoxia-inducible Factor-1 Alpha (HIF-1α), E-cadherin, Galectin 3, IL-4, IL-10 and TNF-α Levels in Individuals With Different Degrees of Periodontal Disease

The study included patients between the ages of 18 and 70 who applied to Karamanoğlu Mehmetbey University Ahmet Keleşoğlu Faculty of Dentistry Department of Periodontology, were non-smokers, had no systemic problems, had not used antibiotics, anti-inflammatory and systemic corticosteroid drugs in the last 3 months, were not pregnant, had not received periodontal treatment in the last 6 months, and having at least 20 teeth in its mouth; for grade A periodontitis group; 20 individuals with a probing pocket depth of 5 mm or more in at least 2 teeth in each quadrant of the jaw, attachment loss, and radiological bone loss percentage/age ratio <0.25 in the tooth with the most bone loss; for grade B periodontitis group; 20 individuals with a probing pocket depth of 5 mm or more in at least 2 teeth in each quadrant jaw, attachment loss, and a radiological bone loss percentage/age ratio of 0.25-1.0 in the tooth with the most bone loss; for grade C periodontitis group; 20 individuals with a probing pocket depth of 5 mm or more in at least 2 teeth in each quadrant of the jaw, attachment loss, and radiological bone loss percentage/age ratio >1.0 in the tooth with the most bone loss; For the healthy group; According to the evaluation made in 6 regions of each tooth, including 20 individuals who show bleeding on probing in less than 20% of the area, have a probing depth of less than 4 mm, and have no attachment loss. The healthy and periodontal disease group will consist of 80 patients in total.Anamnesis will be taken from individuals at the beginning of the interview, and individuals who meet the specified criteria after the anamnesis will be included in the study. After being informed about the study, an informed consent form will be obtained from the individuals.

After the anamnesis is taken, clinical periodontal evaluations will be performed on individuals who are deemed to meet the inclusion criteria. Clinically, plaque index (Sillness and Löe 1964), gingival index (Löe and Sillness 1963), pocket depth and bleeding on probing index(Ainamo&Bay, 1975) will be recorded.

Saliva samples will be taken from individuals divided into groups for biochemical examinations. Saliva samples will be taken from each patient, first frozen at -20ºC and than stored at -28ºC until the day of analysis. Cytokine levels in the samples collected from the patients will be determined by the enzyme-related immune test "Enzyme Linked-Immuno-Sorbent Assay" (ELISA).
