Drug Information available for: Durapatite

Arm Intervention/treatment
Experimental: Amniotic Membrane
The test site was treated as follows; After placement and proper condensation of natural Hydroxyapatite graft in the defect, AM was cut based on defect anatomy of surgical site and then adapted over the bone graft and alveolar bone extending from base of the flap reflection to the tooth surface.
Device: Amniotic Membrane
AM strongly resembles the oral mucosal basement membrane and possesses several types of laminins, which can promote regeneration, accelerate tissue adhesion, and preserve tissues, all of which play a key role in improved healing of periodontal lesions and might result in reduction in probing pocket depth (PPD) and decrease in clinical attachment loss (CAL)
Other Name: TMH Tissue Bank, Mumbai, India

Placebo Comparator: Control group (Hydroxyapatite only)
The control site was treated by graft placement (Hydroxyapatite) only
Device: Control group (Hydroxyapatite only)
The placebo group was treated with Hydroxyapatite graft placement only.

Primary Outcome Measures :
  1. The mean difference in levels of hBD-2/IL-1β [ Time Frame: From Baseline to One month ]
    Commercially available ELISA kits were used to quantify GCF levels of hBD-2 and IL-1β. All assay procedures were conducted according to the manufacturer's instructions and in the test, 100μl of the samples or standards were added into the respective wells in duplicate. Color development was stopped using 1% H2SO4 and absorbance of the entire plate was measured within 30 minutes by an ELISA reader at 450nm. The amounts of hBD-2 and IL-1β were calculated based on the dilutions, and the results were expressed in picograms in the 30-second GCF sample.

Secondary Outcome Measures :
  1. Bone fill assessment [ Time Frame: Baseline to 6 months ]
    The evaluation of bone fill was performed by using digital subtraction technique and morphometric area analysis by using specific tools in two image processing software.

Other Outcome Measures:
  1. Measures of periodontitis and gingivitis [ Time Frame: Baseline to 6 months ]
    Non-invasive site-specific measures of the plaque index (PI) and modified gingival index (MGI) at the baseline, 1 week, 12 weeks and 24 weeks. The PPD, CAL and bone fill were recorded at the baseline (on the day of surgery) and at the end of 12 and 24 weeks. PPD and CAL were recorded at the baseline and at the end of 12 and 24 weeks using a UNC-15 color-coded periodontal probe.

Layout table for eligibility information
Ages Eligible for Study:   30 Years to 55 Years   (Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   Yes

Inclusion Criteria:

Systemically healthy chronic periodontitis patients within the age group of 30-55 years having at least 2 periodontal pockets ≥5 mm with at least 1 pocket in each quadrant showing radiographic evidence of vertical bone loss were included in the study. Assessment of suitability for GTR membrane placement was confirmed by transgingival probing to verify the presence of two well-contained interdental bone defects in as many quadrants.

Exclusion Criteria:

Smokers, medically compromised patients, pregnant women & lactating mothers and subjects receiving periodontal therapy in the 24 weeks (6-month)-period leading to the study were not included.
