%X <B>BACKGROUND: </B>The clinical and radiographic efficacy of bone grafts and biomaterials, such as platelet-rich plasma and platelet-rich fibrin (PRF), for reconstructing lost periodontal structures has been well documented. However, there is limited data regarding the presence of demineralized freeze-dried bone allograft (DFDBA) in an environment with abundant growth factors provided by platelet concentrates.<BR><B>OBJECTIVE: </B>The aim of the study was to compare the clinical and radiographic effectiveness of DFDBA with PRF versus DFDBA alone in the treatment of intrabony defects.<BR><B>METHODS: </B>Twenty-four intrabony defects in contralateral sites were randomly assigned to either the DFDBA group or the DFDBA combined with PRF group. Clinical parameters, including the plaque index (PI), the gingival index (GI), probing pocket depth (PPD), relative attachment level (RAL), and radiographic bone fill (RBF), were measured at baseline, and at 6 and 9 months. Paired and unpaired t-tests were used for intraand intergroup comparisons.<BR><B>RESULTS: </B>Both the PI and the GI showed statistically significant improvements from baseline to 9 months. However, the intergroup comparisons did not reveal any significant differences (p < 0.05) between the groups with regard to clinical and radiographic measurements from baseline to 9 months.<BR><B>CONCLUSIONS: </B>Platelet-rich fibrin in combination with DFDBA did not show any additional benefit in terms of reconstructive output in the treatment of intrabony defects compared to the use of DFDBA alone.
