| Abstract: |
On mixing with an osteoconductive scaffold, recombinant human platelet derived growth factor (rhPDGF-BB), a potent wound-healing protein, has been shown to promote clinical attachment gain and regeneration of the periodontium. This human case report evaluated the clinical outcome of rhPDGF-BB with beta tricalcium phosphate (GEM 21S®) and a collagen membrane in the treatment of recession defects using coronally advanced flap. Patients were followed postoperatively, and healing was evaluated at 1, 3 and 6 months, with recession depth as the primary outcome measure. This pioneer case report revealed a favourable tissue response to GEM 21S® and collagen membrane from both clinical and aesthetic point of view showing full root coverage in two cases. |
