Injectable Platelet Rich Fibrin With Demineralized Freeze-dried Bone Allograft in Treatment of Intraosseous Defects

Clinical and Radiographic Evaluation of Injectable PRF With Demineralized Freeze-Dried Bone Allograft (DFDBA) Compared to (DFDBA) in Treatment of Intraosseous Defects in Patients With Stage III Periodontitis: A Randomized Clinical Trial

Clinical and radiographic evaluation of injectable platelet rich fibrin (i-PRF) and demineralized freeze-dried bone allograft (DFDBA) compared to demineralized freeze-dried bone allograft (DFDBA) alone in management of intraosseous defects in stage III periodontitis patients.

Intraosseous defects are defined by the apical location of the periodontal pocket to the alveolar crest. In a recent radiographic study employing cone-beam computed tomography, a high prevalence of intraosseous defects 83% has been reported. Treatment of intraosseous defects is clinically challenging, as they often require complex regenerative periodontal therapy. Current regenerative techniques often employed in treatment of intraosseous defects demonstrate variation in improvement of clinical outcomes and degree of periodontal regeneration achieved.
