Abstract

Abstract : Background: A wide variety of materials have been proposed for treatment of periodontal intrabony defects (IBDs); recently, platelet‐rich fibrin (PRF) has been suggested as a grafting material. The aim of this study is to report changes in clinical attachment level (CAL) and bone fill of periodontal IBDs treated with demineralized freeze‐dried bone allograft (DFDBA) compared with PRF in humans. Methods: Thirty‐six patients completed the study protocol. Each patient contributed a single IBD, which was randomized to receive either DFDBA or PRF. Clinical and standardized radiographic data were collected at baseline and 6 months after treatment. Primary outcome measures included: 1) radiographic bone fill as measured from the cemento‐enamel junction to base of bony defect and 2) change in CAL. Results: Both treatment groups had significant gains in CAL as well as bone fill, with no significant differences in outcomes between groups. DFDBA had a mean CAL gain of 1.16 ± 1.33 mm, mean clinical bone fill of 1.53 ± 1.64 mm, and mean radiographic bone fill of 1.14 ± 0.88 mm. PRF had a mean CAL gain of 1.03 ± 0.86 mm, mean clinical bone fill of 1.35 ± 1.60 mm, and mean radiographic bone fill of 1.10 ± 1.01 mm. Conclusion: Treatment of IBDs with either DFDBA or PRF resulted in a significant gain in CAL as well as bone fill after 6 months of healing, with no significant difference between materials.
