Clinical Effect of APRF With DFDBA Compare to Collagen Membrane With DFDBA in Intraosseous Defect

Clinical Evaluation of Advanced Platelet Rich Fibrin With (DFDBA) Compared to Collagen Membrane With (DFDBA) in Treatment of Non-contained Intraosseous Defects in Stage III Periodontitis Patients: A Randomized Clinical Trial

to assess the effectiveness of advanced PRF in combination of Demineralized freeze-dried bone allograft (DFDBA) as compared to collagen membrane in combination with Demineralized freeze-dried bone allograft (DFDBA) treatment of non-contained periodontal intraosseous defects in stage III periodontitis patients.

Treatment of intraosseous periodontal defects represents a clinical challenge; these defects have been detected through clinical and radiographic examination in 18- 51 % of patients with periodontitis. They are often associated with persistent deep pockets and bleeding following conventional periodontal treatment. Complex regenerative periodontal therapy is advocated for management of these defects. The outcomes of regenerative periodontal therapy are positively correlated with the morphology of osseous defects. Non-contained defects are prevalent clinically and have been reported to have a low regenerative potential.
