Brief Summary:
Hyaluronic acid (HA) has been used as a dermal filler in medicine for many years. It also has umpteen benefits in terms of aiding in rapid healing and resolution of inflammation. Thus in the present study, HA has been used at the test site to fill papillary recession defects. At the control site saline was injected as the placebo.

Arm Intervention/treatment
Active Comparator: HA filler group
6 weeks after the initial therapy, patients were scheduled for the procedure.16 Local Anesthetic solution (2% Lignocaine HCl with adrenaline 1:80000) was administered.17 About 0.2 ml of a commercially available hyaluronic acid based gel was injected 2-3 mm coronal to the apical tip of the receded interdental papilla . Injections were performed using 23 gauge X 25mm intraoral injection needles . The concentration of HA gel used was 20 mg/ml.6 The area was gently massaged to ensure that the filler was uniformly distributed. Care was taken to fill each papilla to full correction (100% of defect). After the treatment the individual patient syringes were capped and stored in a refrigerator with patient names and details. The needle was discarded. Patients were seen three weeks after the initial treatment and if augmentation was still deemed necessary, another injection of 0.2ml was injected up to three times
Procedure: Hyaluronic acid filler
Papillary augmentation with HA dermal fillers was considered as the test group

Placebo Comparator: saline filler group
with saline same protocol was performed as mentioned in test group
Procedure: Hyaluronic acid filler
Papillary augmentation with HA dermal fillers was considered as the test group

Primary Outcome Measures :
  1. the papillary recession reduction (pRecRed). [ Time Frame: 6 month ]
    . papillary recession depth (distance from the contact point to gingival margin was measured to the nearest millimeter- CP -GM)

  2. percentage papillary coverage(PPC [ Time Frame: 6 month ]

    The formula used to calculate the percentage papillary coverage was as follows-

    Baseline (CP-GM) - 6 month (CP-GM)

    ---------------------------------------------- x 100 Baseline (CP-GM)
