Comparative clinical evaluation of demineralized freeze-dried bone allograft (DFDBA) alone versus DFDBA with platelet-rich fibrin membrane in the management of intrabony defects: A step toward enhanced periodontal regeneration.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Periodontal regeneration in intrabony defects remains a critical goal in periodontics. Demineralized freeze-dried bone allograft (DFDBA) and platelet-rich fibrin (PRF) have shown potential in enhancing clinical outcomes. This study compared the clinical efficacy of DFDBA alone versus DFDBA combined with PRF in the treatment of intrabony periodontal defects. Material and Method: A randomized, double-blinded, split-mouth clinical trial was conducted on patients diagnosed with Stage III or IV, Grade B or C periodontitis, each presenting with paired infrabony defects. A total of 15 defect sites were treated with DFDBA alone (control group), and 15 sites with DFDBA and PRF (test group). Clinical parameters, including probing depth (PD), clinical attachment level (CAL), plaque index (PI), and gingival index (GI), were recorded at baseline, 3 months, and 6 months postoperatively. Statistical analysis was performed using SPSS version 25, with significance set at Results: Both groups showed significant intragroup improvements in all parameters ( Conclusion: Both DFDBA alone and DFDBA combined with PRF significantly improved periodontal parameters. However, the adjunctive use of PRF yielded greater reductions in PPD and superior clinical attachment gains, indicating potential clinical advantages in terms of graft stabilization and soft-tissue healing. Further studies with extended follow-up and histologic evaluation are recommended to substantiate these findings.
