Rh-PDGF vs EMD for Treatment of Intra-bony Defects

Recruiting now · Phase 1/Phase 2

Conditions studied: Intrabony Periodontal Defect

In brief

Treatment of intra-bony defects is challenging and requires extensive knowledge of the etiology, anatomy, occlusion, and available biomaterials that can be used to treat this kind of defects. Patients who received scaling and root planing at the college of dental medicine due to periodontal disease, will be screened for inclusion. Only subjects who showed persistent deep probing depth associated with an intrabony defect will be included and will be randomly allocated to one of two treatment groups. One group will be treated using recombinant human platelet derived growth factor (GEM-21) (test) added to allogenic bone graft, second group will be treated using enamel matrix derivatives (EMD) (control) with allograft. Both groups will be treated using the same surgical protocol. Patients will be followed up for a period of 6 months and 12 months, before getting re-evaluated for assessing the effectiveness of the applied therapies.
