Brief Summary:
assess the clinical and laboratory effects of the local and sub gingival application of a 0.8% hyaluronic acid gel (GENGIGEL®) as an adjunct to scaling and root planning (SRP) in chronic moderate to severe periodontitis patients as indicated by expression of Human Beta Definsin-2 (HBD2) in gingival crevicular fluid (GCF).

Condition or disease Intervention/treatment Phase
Periodontitis Drug: 0.8% Hyaluronic Acid Procedure: Scaling and Root Planing Phase 4

Detailed Description:

Patients who fulfilled the selection criteria will be included in the study. One quadrant will be treated with HA gel (test) and the other without to serve as control. Clinical examination will be done in a dental chair under standard conditions of light, using mouth mirror and graduated Williams Periodontal Probe.

All patients will receive full mouth scaling and root planing with hand instruments and ultrasonic scalers at baseline. Thereafter, in the test quadrant, 1 ml of 0.8% hyaluronic acid gel will be administered subgingivally in all selected test sites at baseline and 1 week later. The following clinical parameters will be recorded at baseline, after 6 weeks and 12 weeks post treatment. Oral hygiene instructions will be given to all patients. The clinical measurements and treatment will be performed by a single examiner.For every patient and control subject, GCF samples will be collected at baseline, 6 weeks and 12 weeks post treatment. The samples will be pooled from two periodontal sites with clinical attachment level of 3 mm or more (in the two different quadrants). The sampling area will be isolated with cotton rolls and carefully will be cleaned supragingivally with sterile cotton pellets. A sterile absorbent paper point will be inserted into the gingival crevice or pocket until resistance will be felt. The paper point will be held in place for 30 s and then will be transferred to a vial containing 100 μL of distilled water and vigorously will be mixed. The paper points will be removed, and the samples will be centrifuged and will be washed twice with distilled water. The resultant pellets will be resuspended in 0.4 mL of distilled water. The samples will be coded and stored at −70 °C until use for ELISA test for identification of Human beta Defensin-2.

Primary Outcome Measures :
  1. Clinical Attachment Level (CAL) change [ Time Frame: baseline, six weeks, 12 weeks ]
    Distance from the cementoenamel junction to the base of gingival sulcus using a UNC15 probe

  2. Probing Depth change [ Time Frame: baseline, six weeks, 12 weeks ]
    It's the distance from the gingival margin to base of the sulcus

  3. Gingival Index change (Loe and Silness, 1963) [ Time Frame: baseline, six weeks, 12 weeks ]
    To assess the gingival condition and record qualitative chances in the gingiva

  4. Plaque index change (Loe and Silness, 1964) [ Time Frame: baseline, six weeks, 12 weeks ]
    To measure the state of oral hygiene

  5. Papillary Bleeding Index change (Muhlemann, 1977) [ Time Frame: baseline, six weeks, 12 weeks ]
    immediate evaluation of the patient's gingival motivation and condition

Secondary Outcome Measures :
  1. HBD-2 change [ Time Frame: baseline, six weeks, 12 weeks ]
    By take gingival crevicular fluid sample elisa test
