EVALUATION OF EFFICACY OF DEMINERALIZED FREEZE DRIED BONE ALLOGRAFT WITH AND WITHOUT PLATELET-RICH FIBRIN IN THE TREATMENT OF INTRABONY DEFECTS BY CONE BEAM COMPUTED TOMOGRAPHY: A CLINICAL AND RADIOGRAPHIC STUDY

Background: Eventhough the combination of DFDBA (demineralized freeze dried bone allograft) with PRF (platelet-rich fibrin) has been attempted in periodontal practice with significant results, assessment of the intrabony defect and defect bone fill largely done with two-dimensional imaging modalities. Three dimentional analysis of the intrabony defect and defect bone fill has not been attempted with cone beam computer tomography (CBCT). The present study evaluated the efficacy of DFDBA with and without PRF in the treatment ofintrabony defects by CBCT.

Methods: 60 defects in systemically healthy patients ranging from 18 to 50 years of age will be included in the study.30 defects were treated with PRF+DFDBA and 30 defects were treated with DFDBA alone. The study will include the assessment of clinical parameters involving probing depth (PD), relative attachment level(RAL), full mouth bleeding scores(FMBS),plaque index and gingival index from baseline to 3 , 6, 9 months. Hard tissue changes will be assessed radiographically by evaluating defect fill and defect resolution by CBCT at baseline& 9 months.

Results: The results of the present study are statistically significant in both groups in terms of clinical and radiographical parameters (P < 0.001). In inter-group comparison, there was a statistically significant greater PD reduction and attachment gain while there was not significant reduction in terms of PI, GI, FMBS, defect fill and defect resolution in DFDBA+ PRF group.

Conclusion: DFDBA along with PRF failed to provide additional value in terms of defect fill and defect resolution over DFDBA alone.
