Evaluation of Salivary Asprosin, IL-39,IL-40 and IL-1β Levels in Diabetic Patients with Periodontitis
Evaluation of Salivary Asprosin, IL-39,IL-40 and IL-1β Levels in Diabetic Patients with Periodontitis
The aim of this study is to determine the relationships between asprosin, IL-39, IL-40 and IL-1β in saliva between individuals with and without diabetes and between individuals with periodontitis and healthy individuals and to determine the potential roles of these biomarkers that are multiplied in periodontal disease. The study aims to evaluate whether these biomarkers can be used for periodontal diagnosis or prognosis.
The questions answered by the study are as follows:
Do asprosin, IL-39, IL-40 and IL-1β biomarker levels differ between individuals with and without diabetes? Do these biomarker levels differ significantly between individuals with periodontitis and individuals who are healthy? Can these biomarkers be used in the early diagnosis or recording the progression of periodontal diseases?
The study is planned to be conducted with 176 individuals with and without periodontal disease between the ages of 18-80 who come to the Department of Periodontics of the Faculty of Dentistry of Necmettin Erbakan University for treatment. Those who sign the 'informed consent form' will be included in the study.
In the periodontal examination of each patient who applies to the periodontology clinic, routine radiographic and clinical evaluations are performed, and routine periodontal status records (periodontal pocket depths of the teeth, attachment losses, mobility levels, furcation defect degrees, bleeding index on probing, gingival index, plaque index, amount of keratinized gingiva, gingival recessions, body/mass index) are taken and archived before the start of the patients' treatments and after each planned treatment. In addition, the sociodemographic data and brushing habits of each patient who will participate in the study are recorded. Saliva samples will also be collected from patients prior to treatment. Individuals will be divided into groups according to their periodontal disease status:
A calibrated expert clinician will determine periodontal status according to the criteria of the 2017 World Workshop on Classification of Periodontal and Peri-Implant Diseases and Conditions based on radiographic and clinical examination. Patients will need to meet the criteria for Stage II and III, generalized, periodontitis to be included in the periodontitis groups.
Saliva samples will be collected before periodontal measurements are taken to prevent saliva from bleeding during probing. Participants will be asked not to brush their teeth at least one hour before the sample collection and to avoid any food, sugary gum, cosmetic products such as lipstick, and any medication that will not affect the salivary hormone measurements. A total of 5 2 ml samples, one for each marker, will be collected from each patient between 9:00 and 10:00 in the morning. The samples will be collected in plastic tubes with a glass funnel within five minutes after each participant rinses their mouth with water. The tubes will then be capped and the samples will be centrifuged at 1000 rpm for 10 minutes to remove cellular elements and plaque. The supernatant liquid will be pipetted without touching the sediment formed at the bottom of the tubes, placed in polypropylene Eppendorf tubes, and stored at -20°C until analysis.
Analysis of Saliva Samples Samples will be placed at +4°C to be thawed on the day of analysis. ELISA kits will be used to determine Asprosin, IL-39,IL-40, IL-38 and IL-1B levels according to the manufacturer's instructions (Elabscience Biotechnology Co. Ltd).
Statistical Analysis Statistical analysis will be performed using the Statistical Package for Social Sciences (SPSS) version 23 (IBM Corp., Armonk, NY).
Data will be expressed as mean and standard deviation. Data normality will be assessed using the Kolmogorov-Smirnov test. Differences between parameter means in intragroup comparisons of periodontally healthy and periodontitis groups will be assessed using the One-way ANOVA (Bonferroni post-hoc) test. Differences between parameter means between periodontally healthy and periodontitis groups will be assessed using the independent t test. Pearson correlation coefficients will be used to assess correlations between clinical and biochemical parameters. Areas under the curve (AUC) and receiver operating characteristic (ROC) curves will be used to examine the sensitivity and specificity of salivary biomarkers in distinguishing periodontitis from periodontal health. p<0.05 will be considered statistically significant.
