Tissue Plasminogen Activator & Plasminogen Activator Inhibitor Type-1 In Gingival Tissues Of Chronic Periodontitis

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT03803176

Brief Summary:
Tissue Plasminogen Activator and Plasminogen Activator Inhibitor Type-1 Gene Expression will be evaluated clinically and histopathologically through Hematoxylin and eosin as well as by quantitative reverse transcription polymerase chain reaction in the gingival tissues of chronic periodontitis in an attempt to investigate whether the expression of these proteins could be involved in the disease pathogenesis or not, and to assess as well if their expression will be affected by the applied surgical periodontal treatment.

Condition or disease Intervention/treatment
Chronic Periodontitis Procedure: Open Flap Debridement

Detailed Description:
30 subjects were enrolled in this study and divided into: Group I (Control Group): 10 periodontally healthy volunteers, Group II (Chronic Periodontitis Group): 20 patients suffering severe CP and Group III (Treated Group): 20 patients who were scheduled for OFD. Gingival samples were collected from all subjects at baseline and at 3 months after OFD from the CP patients. Then, Hematoxylin and eosin (H&E) stained slides were examined and gene expression levels of t-PA and PAI-1 were measured in the gingiva through quantitative reverse transcription polymerase chain reaction (RT-PCR).

Observational Model: Case-Control
Time Perspective: Prospective
Target Follow-Up Duration: 4 Months
Official Title: Effect Of Periodontal Surgery On Tissue Plasminogen Activator And Plasminogen Activator Inhibitor Type-1 Gene Expression In Gingival Tissues Of Chronic Periodontitis Patients
Actual Study Start Date : February 12, 2018
Actual Primary Completion Date : June 11, 2018
Actual Study Completion Date : August 14, 2018

Group/Cohort Intervention/treatment
Periodontally healthy subjects
Healthy subjects who attended the restorative dental clinic and have clinically healthy gingiva with zero plaque index (PI), gingival index (GI), and CAL (≤3 mm PD). Oral hygeine instructions will be given to these patients.
Chronic Periodontitis
Patients with severe Chronic Periodontitis having a pocket depth (PD) of ≥5 mm and a clinical attachment level (CAL) ≥5 mm. Open flap debridement (surgical periodontal therapy) will be carried out for these patients after scaling & root planing.
Procedure: Open Flap Debridement
Full thickness flaps are elevated to fully expose the periodontaldefects. Defects are then fully debrided and the roots are carefully planned. Flaps are repositioned and sutured to obtain primary closure of the interdental space. This will be done for chronic periodontitis patients

Primary Outcome Measures :
  1. Clinical attachment level [ Time Frame: 4 weeks ]
