Brief Summary

All 16 chronic periodontitis (CP) subjects were clinically examined regarding the following clinical periodontal parameters: plaque index (PI), gingival index (GI), bleeding index (BI), Pocket Probing Depth (PPD) and Relative Attachment Loss (RAL) which were recorded for all patients at baseline and 3 months after surgical periodontal treatment. Pre- surgical procedure: After the clinical parameters were recorded, Phase I therapy (full mouth scaling, root planning and oral hygiene instructions) was carried out. The patients were then put under observation to assess the oral hygiene practice and the response of the gingival tissue to Phase I therapy. After two weeks, patients were recalled and based on further treatment protocol, periodontal flap surgery was planned. Group A (Test Group) underwent periodontal flap surgery during which placental extract was applied. Group B (Control Group) underwent periodontal flap surgery alone. Surgical procedure The operative sites were anaesthetized with 2% lignocaine hydrochloride with adrenaline (1:180000). Crevicular incisions were made using Bard Parker No.15 blade on the facial and lingual/palatal surface of each tooth segment or area involved. A full thickness mucoperiosteal flap was reflected using periosteal elevator taking care to preserve the maximum amount of tissue in the flap. After exposure the granulation tissue was removed, the root surfaces were planed and the flap was trimmed of tissue tags to facilitate healing. The flap was approximated using interrupted sutures (mersilk 3-0) and a periodontal dressing was placed above it. Local delivery of the placental extract In group A patients (test group) after open flap debridement 1ml of human placental extracts gel (Placentrex - the original research product of Albert David Limited, India, a drug obtained from fresh term healthy human placentae) was dispensed in a dappen dish. Gelatin foam (Abgel, Sri Gopal Krishna Labs, Pvt.Ltd. India) was cut into small beads of 1 sq.mm and allowed to soak in the placental gel for a few seconds. These gelatin beads soaked in gel are placed into the surgical site locally with the help of a graft carrier and condensed into the defect area. To prevent uncontrolled spill-over effects of the gel, mild pressure was applied over the flap with the wet gauze and excess gel was removed and Coe Pak was placed. While in group B(control group), after open flap debridement, this step is omitted. Post-operative care Antibiotics and analgesics are prescribed two times a day for five days. Patients were instructed to refrain from chewing hard or sticky foods, brushing near the treated areas or using any interdental aids for 1 week. The use of mouthwash was avoided during the observation period. All patients were placed on a strict maintenance schedule following surgery. The sutures were removed 10 days later. Recall appointments were scheduled once in 10 days for the 1st month. At every recall appointment, oral hygiene was checked. At 3rd month, the clinical parameters were recorded in both the groups. The difference between pre and post-operative values was assessed and then statistically analysed

Outcome Measures

Primary Outcomes (6)

• Pocket Probing Depth (PPD)

  Measurements were taken from stent to deepest probing depth to record Probing pocket depth (PPD)

  Change from Baseline Periodontal disease at 3 months

• Relative Attachment Loss (RAL)

  Relative Attachment level (RAL) were recorded by subtracting the length of deepest probing depth from stent by the length from stent to cemento-enamel junction.

• Plaque Index (PI)

  The scoring is done on the entire dentition or on selected teeth. Plaque of the cervical third of the tooth is evaluated with no attention to plaque that has extended to the middle or incisal thirds. The surfaces examined are the four gingival areas of the tooth i.e. the disto-facial, facial, mesio-facial, and lingual surfaces. Scoring criteria: 0 No plaque 1. A film of plaque adhering to the free gingival margin and adjacent area of the tooth. The plaque may be in situ only after application of disclosing solution or by using probe on the tooth surface. 2. Moderate accumulation of soft deposit within the gingival pocket, or the tooth and the gingival margin which can be seen with naked eye. 3. Abundance of soft matter within the gingival pocket and/or on the tooth and gingival margin.

• Gingival Index (GI)

  The severity of gingivitis is scored on the mesiofacial and distofacial papillae, facial and lingual margin of selected teeth.A blunt instrument is used to assess the bleeding potential of tissues.The index relies entirely on visual criteria of gingivitis and eliminates the use of probing or pressure to establish the presence or absence of bleeding. Score Criteria 0 Absence of inflammation/normal gingiva 1. Mild inflammation, slight change in color, slight edema; no bleeding on probing 2. Moderate inflammation; moderate glazing, redness, edema and hypertrophy. Bleeding on probing. 3. Severe inflammation; marked redness, hypertrophy and ulceration. Tendency to spontaneous bleeding * G.I SCORE = Total score / No of teeth examined Rating Score Mild gingivitis=0.1-1.0 Moderate gingivitis=1.1-2.0 Severe gingivitis =2.1-3.0

• Bleeding Index (BI)

  The gingival bleeding index of Ainamo J and Bay I was developed as an easy and suitable way for assessing a patient's progress in Plaque control. The presence or absence of gingival bleeding is determined by gentle probing of the gingival crevice with a periodontal probe. The appearance of bleeding within 10 seconds indicates a positive score, which is expressed as percentage of the total number of gingival margin examined. • Scoring criteria: Score Criteria 0 No bleeding present on probing within 10 seconds 1 Bleeding present on probing within 10 seconds. • Calculation : = Total score / No of teeth examined

  Change from Baseline Periodontal disease at 3 months

• periostin levels

  Collection of gingival crevicular fluid GCF samples were obtained from the buccal aspects of the selected site. The sites were isolated by cotton rolls, rinsed with water and dried with a gentle air spray directed perpendicular to the gingival margin. Removal of supra-gingival plaque was completed utilizing dry gauze, and a sterile filter paper strip((ORAFLOW). ® was gently inserted into the entrance of the selected site until the first sign of resistance was felt for 30 sec. Samples contaminated with gingival bleeding were excluded. The GCF sample volume will be measured in a calibrated appliance (Periotron 8000 Proflow Inc., Amityville, NY, USA) TM, after which the reading will be converted to an actual volume (µl) by reference to the standard curve.
