About this study
Official title: Prognostic Potentials of E-cadherin and Total Antioxidant Capacity in Gingival Crevicular Fluid of Moderately Deep Periodontal Pockets Treated With Nonsurgical Periodontal Therapy
Ability to anticipate the outcomes of periodontal therapy at baseline visit is crucial to outline and customize a treatment plan with predictable outcomes and cost-effectiveness. Presence of diverse range of health/disease-associated molecules in oral environment that reflect health and disease, together with clinical parameters, is an appealing approach to use them as biomarkers to diagnose, predict, and monitor periodontal disease. Among these proteins are E-cad and TAC which available evidence indicate that their concentrations in oral biofluids increase remarkably during periodontitis as compared to healthy periodontium.
Read the detailed description
Loss of attachment and formation of periodontal pockets are hallmarks of periodontitis. The treatment approach is either by nonsurgical or surgical periodontal therapy or a combination of both depending on the severity of the case. In general, sites with moderately deep pockets (4 to 6 mm) are responding favorably to nonsurgical periodontal therapy (NSPT). Nevertheless, some sites exhibit persistent pockets even with multiple treatment sessions which could be attributed to the presence of tissue invaders or aberrant immune response that impede healing process.
Prediction of treatment outcomes based on clinical data is limited and sometimes lacking accuracy. Use of biomarkers that can be non-invasively collected from oral fluids e.g., gingival crevicular fluid (GCF) as diagnostic/predictive tools has gained attention in the last decade. For instance, E-Cadherin (E-cad) and total antioxidant capacity (TAC) are associated with periodontitis. E-cad is a transmembrane glycoprotein that is a key mediator of stable cell-cell adhesion of epithelial cells. E-cadherin-based adherens junctions specialized cell structures that mediate cell-cell adhesion and regulate cytoskeleton reorganization forming a continuous, linear circumferential belt (zonula adherens) around the apical part of the cell. While TAC, defined as the moles of oxidants neutralized by one liter of solution, is a biomarker measuring the antioxidant potential of body fluids.
Available evidence indicates that the concentration of both molecules are substantially increased with increasing severity of periodontitis and vice versa in periodontal health. This suggests the potential of GCF-E-cad and TAC to predict the prognosis following NSPT.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Root surface debridementProcedure or surgery
the included patients will undergo full-mouth supra- and subgingival debridement by using ultrasonic device and manual instrumentation at baseline. This is followed, after 1 week, by performing root surface debridement for all pockets with PPD = 4-6 mm for each patient. All patients will be instructed to brush their teeth twice daily and will be supplied with the same type of tooth paste and toothbrush, with suitable interdental aids.
| Study group | Role | What they receive |
|---|---|---|
| Root surface debridement | Other | Periodontal pockets with PPD of 4 to 6mm are treated with root surface debridement only and assessed after 3 months for success/failure of treatment. Receives: Procedure: Root surface debridement |
What is being measured
The primary outcome is the main question the study is designed to answer.
Probing pocket depth
Linear distance, in mm, measured from the gingival margin to the base of periodontal pocket or sulcus.
Measured: Baseline, 1 week, then 1 month and 3 months after treatment
Secondary outcomes (4)
Clinical attachment loss
Linear distance, in mm, measured from the cementoenamel junction to the base of periodontal pocket or sulcus.
Measured: Baseline, 1 week, then 1 month and 3 months after treatment
Bleeding on probing
Presence or absence of bleeding is detected after 30 seconds of inserting periodontal probe to the depth of periodontal pocket/sulcus
Measured: Baseline, 1 week, then 1 month and 3 months after treatment
Gingival crevicular fluid E-cadherin
Level of E-cadherin in GCF collected from periodontal pockets is determined by biochemical analysis
Measured: Baseline, 1 month and 3 months after treatment
Total antioxidant capacity
Level of TAC in GCF collected from periodontal pockets is determined by biochemical analysis
Measured: Baseline, 1 month and 3 months after treatment
