GCF Levels of IL-1β and IL-6 in Gingivitis and Stage III-Grade C Periodontitis
Study Details
Study Description
Brief Summary
Periodontal diseases are chronic diseases that occur as a result of a violation of the balance between microbial dental plaque and the host response. Gingivitis is a disease characterized by inflammation of the gingiva that occurs in one or more areas without loss of attachments.1 in periodontitis, an inflammatory event that begins in the gingiva along with gingivitis spreads to the periodontal ligament, alveolar bone and soft tissues that support the tooth, causing the destruction of these structures.2 Cytokines are low molecular weight proteins that participate in the initial and active stages of inflammation and immunity. In periodontal disease pathogenesis, cytokine response has been reported to play a very critical role in determining disease progression.3 IL-1beta and IL-6 are key cytokines in chronic inflammatory diseases and have the potential to initiate bone loss and tissue destruction seen in periodontal disease.4the purpose of this study; it is to determine the degree of inflammation and periodontal destruction by determining the levels of IL-1beta and IL-6 cytokines in the gingival crevicular fluid of periodontal healthy and diseased individuals.

Detailed Description
Plaque index (PI), gingival index (GI), presence of bleeding on probing (BOP), pocket depth (PD) and clinical attachment level (CAL) were used during the clinical periodontal assessment at 6 sites per tooth except third molar. All periodontal assessments were conducted with a manuel probe* by an experienced calibrated periodontist (AD). Calibration exercises were performed in 5 non-study periodontitis patients for probing depths (PD) and attachment loss (AL). The reproducibility of the parameters was verified via the kappa coefficient, which was 0.90 for PD and 0.88 for AL. After clinical evaluation, individuals were divided into 6 groups according to the 2017 World Workshop on the Classification of Periodontal and Peri-implant Diseases and Conditions (Chapple and Papapanou).
- Healthy control groups:
Consisted of individuals with clinically healthy gingiva on an intact periodontium who had a BOP score less than 10% and PD≤3mm, showed no attachment loss or radiographic bone loss.
- Gingivitis groups:
Consisted of individuals with a BOP score of 10% or greater and PD≤3mm with no attachment or radiographic bone loss.
- Stage III -Grade C periodontitis groups:
Consisted of individuals with interdental AL ≥5 mm, radiographic bone lose extending to middle or apical third of the root, PD≥6 mm and tooth loss due to periodontitis of ≤4. Rapid bone loss is observed compared to biofilm and % Root Bone Loss/age >1.0 is determined as grade C.
AL caused by root caries in the cervical region of the tooth, gingival recession caused by traumatic reasons, distal region of the second molar tooth due to extraction of the third molar, lesion in the marginal periodontium of endodontic origin, vertical root fracture were excluded from the study because they were not periodontal origin.
GCF samples were collected in the morning hours 24-48 hours after clinical periodontal measurement. GCF was obtained using strips of filter paper† from the buccal part of an interproximal region in each quadrant. In the Periodontitis group, GCF was obtained from the regions where the most radiographic bone loss and SCD were observed. In these areas, if any, the plaque was slightly removed with sterile tools, and the area was isolated with cotton rolls. After drying the teeth with air, paper strips were placed in the gingival sulcus so that they remained there for 30 seconds. Strips contaminated with blood or saliva were removed from the study. The volume of absorbed GCF was determined by a calibrated electronic device (Periotron 8010, oraflow). The strips were then immediately transferred to sterile polypropylene tubes and frozen at -40°C for storage until analysis was carried out.The data obtained in this study will be analyzed using the SPSS 17 package program. Kolmogorov-Smirnov and Shapiro Wilk's tests will be used to investigate the states of variables coming from the normal distribution. 0.05 will be used as the level of significance when interpreting the results; if p<0.05, it will be stated that the variables do not adapt to the normal distribution, and if p>0.05, the variables adapt to the normal distribution. If the variables do not adapt to the normal distribution, nonparametric Kruskal Wallis-H tests will be used when examining the differences between the groups.
