Effect of Periodontal Treatment on Visfatin, fetuin-a and Sirtuin 1 of Patients With Periodontitis and Type 2 Diabetes
Condition: Periodontal Diseases; Type 2 Diabetes; Periodontitis
MeSH terms: Periodontitis; Periodontal Diseases; Diabetes Mellitus; Diabetes Mellitus, Type 2
Study type: Interventional

Summary: 
      The aim of this study is to determine the concentrations of Visfatin, Fetuin-A and Sirtuin 1
      in the gingival crevicular fluid and clinical periodontal parameters in diabetic and
      systemically healthy individuals and to determine whether non-surgical periodontal treatment
      had any effect on these biomarkers and periodontal clinical parameters at the end of a
      3-month follow-up period. The hypothesis of our study is that gingival crevicular fluid
      Visfatin, Fetuin-A and Sirtuin 1 concentrations will change with non-surgical periodontal
      treatment in type 2 diabetic and systemically healthy individuals and that this change will
      be associated with diabetes and clinical parameters.
    

Detailed description: 
      Sixty-six patients were divided into six equal groups; group 1: systemically and
      periodontally healthy individuals, group 2: systemically healthy individuals with
      periodontitis, group 3: controlled type 2 diabetes and periodontally healthy individuals,
      group 4: controlled type 2 diabetes and periodontitis, group 5: uncontrolled type 2 diabetes
      and periodontally healthy individuals, group 6: uncontrolled type 2 diabetes and
      periodontitis. The study was planned as a randomized, single-blind, parallel design.
      Periodontal clinical parameters (Silness-Löe plaque index, Löe-Silness gingival index,
      probing pocket depth, clinical attachment level, bleeding on probing) were recorded
      clinically and concentrations of visfatin, fetuin-A and sirtuin 1 in gingival crevicular
      fluid were assessed biochemically. After baseline examinations, periodontal treatment was
      completed using a nonsurgical periodontal treatment protocol completed in 24 hours.
      Periodontal clinical parameters and gingival crevicular fluid were recorded at baseline and 3
      months after periodontal treatment. Biochemical analysis and statistical evaluation were
      performed.
    

Intervention name(s): GCF (gingival crevicular fluid) collection; Non-surgical periodontal treatment completed in 24 hours; HbA1c level determination in blood serum
Intervention type(s): Diagnostic Test; Procedure; Diagnostic Test
Intervention description(s): Prior to GCF (gingival crevicular fluid) sampling, supragingival plaque was removed by sterile curets and, after air drying, the surfaces were isolated by cotton rolls. Gingival fluid collection strips were placed in sulcus for 30s. Care was taken not to avoid mechanical trauma and strips contaminated with blood or saliva were discarded. The absorbed GCF volume was estimated by a calibrated instrument. Then, the strips were sealed into sterile tubes before freezing at -80 °C. The readings were converted to an actual volume (μl) by reference to the standard curve.; After clinical periodontal parameters were recorded and GCF samples were obtained, non-surgical periodontal treatment was started under local anesthesia. All periodontal treatments were performed by a single investigator. Local infiltrative anesthesia was applied to the buccal and palatal/lingual areas of the maxilla and mandible of the patients. After anesthesia was achieved, scaler and ultrasonic tips of various thicknesses were used together to remove supragingival and subgingival hard attachments. Root surface smoothing was performed with region-specific periodontal curettes. The roughness of the surfaces was controlled using a periodontal probe. Polishing was performed. Oral hygiene education was given to each patient after treatment. Modified Bass technique was explained as a brushing technique. Interdental cleaning is explained. The patient was told not to use any chemical agent for plaque removal.; Blood samples were taken from the patients and HbA1c concentration was measured in serum.
Allocation: Randomized
Intervention model: Parallel Assignment
Intervention model description: Sixty-six patients were randomly divided into six equal groups; group 1: systemically and periodontally healthy individuals, group 2: systemically healthy individuals with periodontitis, group 3: controlled type 2 diabetes and periodontally healthy individuals, group 4: controlled type 2 diabetes and periodontitis, group 5: uncontrolled type 2 diabetes and periodontally healthy individuals, group 6: uncontrolled type 2 diabetes and periodontitis. The study was planned as a randomized, single-blind, parallel design. Periodontal indexes were recorded clinically and the concentrations of visfatin, fetuin-A and sirtuin 1 in gingival crevicular fluid were assessed biochemically. After baseline examinations [Silness-Löe plaque index (PI), Löe-Silness gingival index (GI), probing pocket depth (PPD), clinical attachment level (CAL), bleeding on probing (BOP)], initial periodontal treatment was completed using a full-mouth treatment protocol. Data were collected at baseline and at 3 months.
