Evaluation of efficacy of autologous platelet-rich fibrin with demineralized-freeze dried bone allograft in the treatment of periodontal intrabony defects



Evaluation of efficacy of autologous platelet-rich fibrin with demineralized-freeze dried bone allograft in the treatment of periodontal intrabony defects



Journal of Indian Society of Periodontology 17(3): 361-366



Platelet-rich fibrin (PRF), an intimate assembly of cytokines, glycan chains, and structural glycoproteins enmeshed within a slowly polymerized fibrin network, has the potential to accelerate soft and hard tissue healing. The purpose of the study was to clinically evaluate and compare the efficacy of autologous PRF combined with demineralized freeze-dried bone allograft (DFDBA) to DFDBA alone in the treatment of periodontal intrabony defects. In a split mouth study design, 10 patients having two almost identical intrabony defects with clinical probing depth of at least 6 mm were selected for the study. Selected sites were randomly divided into two groups. In Group I, mucoperiosteal flap elevation followed by the placement of DFDBA was done. In Group II, mucoperiosteal flap elevation followed by the placement of homogeneous mixture of PRF with DFDBA was done. Clinical and radiographic parameters were recorded at baseline and at 6 months post-operatively. Both treatment groups showed a significant probing pocket depth reduction, clinical attachment gain, defect fill, and defect resolution 6 months after surgery compared to baseline. However, there was a significantly greater probing pocket depth reduction and clinical attachment gain when PRF was added to DFDBA. Within limits of the study it may be concluded that a combination of PRF with DFDBA demonstrated better results in probing pocket depth reduction and clinical attachment level gain as compared to DFDBA alone in the treatment of periodontal intrabony defects.
