Brief Summary

Periodontitis is an inflammatory disease characterized by periodontal tissue destruction caused by bacterial infection. The immune response plays an important role in the progression of periodontitis. The disease process starts with periodontopathogens in dental plaque, and tissue destruction is mainly caused by the immune response of the host to the etiological microorganism and cytokine profile through various inflammatory cytokines. The cytokine response, which plays a critical role in the pathogenesis of periodontal disease, determines the progression of the disease. Evaluation of the effects of IL-6, IL-17 and IL-35 levels in the gingival crevicular fluid on periodontal disease together with clinical parameters has been the basis of our study. This study consists of individuals with grad B-C stage III-IV periodontitis and healthy individuals, which is the subtitle of Periodontal and Periimplant Diseases and Conditions in the classification renewed in 2017. It is aimed to examine the changes and possible correlations in IL-6, IL-17, IL-35 levels as a result of biochemical examination of the samples taken from the gingival crevicular fluid. In our study, according to the new classification of 2017, gingival crevicular fluid samples collected from individuals with grade B-C stage III-IV periodontal disease and healthy individuals under appropriate conditions and techniques were measured for IL-6, IL-17 and IL-35 by enzymatic immunosorbent test (ELISA). It aims to investigate the negative/positive correlations and compare the increases-decreases.

Outcome Measures

Primary Outcomes (1)

  • Measurement of GCF samples

    Measurement of IL-6, IL-17, IL-35 levels in GCF in grade B-C stage III-IV periodontitis individuals.

    GCF samples were collected after first week of clinical periodontal measurement. GCF was obtained using paper strips from the deepest gingival groove.

Secondary Outcomes (1)

  • Measurement of GCF samples

    GCF samples were collected after first week of clinical periodontal measurement. GCF was obtained using paper strips from the deepest gingival groove.

Study Arms (2)

Grade B-C stage III-IV periodontitis group

Grade B-C stage III-IV periodontitis group Grade B: Moderate Moderate bone loss is observed compared to biofilm and % Root Bone Loss/age 0.25 to 1.0 is determined as grade B. Stage III: Severe 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. Grade C: Rapid Rapid bone loss is observed compared to biofilm and % Root Bone Loss/age \>1.0 is determined as grade C. Stage IV:Advanced 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 ≥5. Need for complex rehabilition due to: Masticatory dysfunction, Secondary occlusal trauma(tooth mobility degree ≥2) Severe ridge defect,Bite collapse, drifting, flaring. Less than 20 remaining teeth (10 opposing pairs)

Other: No intervention was applied to the groups the samples will be collected in terms of the diagnosis (periodontitis, healthy)

Healthy control group

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.

Other: No intervention was applied to the groups the samples will be collected in terms of the diagnosis (periodontitis, healthy)

Sampling MethodProbability Sample
Study Population

In our study, individuals who have Grade B-C stage III-IV periodontal disease according to the 2017 Classification of Periodontal and Peri-implant Diseases and Conditions and individuals who have healthy gingiva will be selected.

You may qualify if:

  • years old
  • Not having any systemic disease (diseases that do not affect the periodontal status)
  • Non-smoker
  • Have not received antibiotic treatment and/or used immunosuppressant medication in the last 6 months
  • Have not received any periodontal treatment before
  • No pregnancy and breastfeeding status
  • Not using any medication regularly
  • Having at least 20 teeth
  • Those with grade B-C stage III-IV periodontal disease according to the 2017 Classification of Periodontal and Peri-implant Diseases and Conditions
  • In patients who applied to Istanbul University Faculty of Dentistry, Department of Periodontology, periodontally healthy individuals who do not meet the above disease criteria, who do not have a history of periodontitis in any way, will be included in the study. 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.

You may not qualify if:

  • Those with systemic modifying disease affecting periodontal status
  • Smoker
  • Have received antibiotic therapy or immunosuppressive therapy in the last 6 months
  • Previously received periodontal treatment in the last 6 months
  • Pregnancy and breastfeeding status
  • Regular use of drugs that will affect systemic health
