BACKGROUND: Guided tissue regeneration has recently been advocated in re-constructing soft-tissue dimensions in recession defects. Advancement in nanotechnology has led to increased zest for approaches such as electrospinning of biologically active; nanofibrous functionally graded regenerative membranes for periodontal tissue engineering. A functionally graded membrane (FGM) had been tailored by incorporating chitosan and nano-hydroxyapatite over Amnion membrane and used in gingival recession defects.
STUDY DESIGN: It was single-blind, randomized controlled study. Split-mouth study was conducted in nine patients and 22 sites with recession defects were selected. Sites were divided into Group A (Amnion membrane with coronal advanced flap) and Group B (FGM with coronal advanced flap).
MATERIALS AND METHODS: Sites were assessed clinically by recording plaque index (PI), gingival index (GI), vertical recession defect depth (VRDD), relative clinical attachment level (CAL), and width of keratinized tissue at baseline, 3-6 months; and radiographically by recording linear bone growth by dentascan at baseline and 6 months.
RESULT: Both groups showed statistically significant reduction in PI, GI and VRDD, and CAL and nonsignificant reduction in width of keratinized tissue at 3 and 6 months postoperatively. Group A showed statistically significant linear bone growth at 6 months. Group B also showed gain in linear bone growth at 6 months; however, result was statistically nonsignificant.
CONCLUSION: FGM had shown favorable results by enhancing bone growth while preventing the gingival tissue downgrowth.
