Comparative Evaluation of Injectable Platelet Rich Fibrin (I-PRF) with DFDBA and Titatium Prepared Platelet Rich Fibrin (T-PRF) with DFDBA In The Treatment of Infrabony Defects In Chronic Periodontitis Patients - A Clinico-Radiographical Study

Abstract

Objectives: The main objective of this study was to evaluate the efficacy of Titanium prepared platelet-rich Fibrin (T-PRF)  and Injectable Platelet Rich Fibrin (I-PRF) with demineralized freeze-dried bone allograft (DFDBA) in order to improve the clinical and radiographic results obtained in treatment of periodontal infrabony defects.

Materials and Methods: This  split-mouth randomized controlled clinical trial was conducted on 30 subjects with two comparable bilateral infrabony defects. Plaque Index(PI), Gingival Index(GI) Clinical attachment level (CAL), Periodontal Pocket depth (PD), as well as radiographic parameters IOPA including the radiographic defect size,  were measured at six months post-operatively.

Results: The mean reductions in PD and CAL were 4.0±0.77 mm and 2.5±0.68 mm in sites treated with I-PRF+DFDBA, respectively (P<0.05); these reductions were 4.2±0.86 mm and 3.1±0.62 mm, respectively in T-PRF+DFDBA group (P<0.05). Radiographic evaluation revealed reduction in the radiographic defect size in the I-PRF+DFDBA and T-PRF+DFDBA sites. Statistically, there were no significant differences between the two treatment modalities.?

Conclusion: This study showed that both treatments resulted in significant improvement in the probing depth reduction, clinical attachment level gain and radiographic size of the infrabony defect at six months after surgery. I-PRF with DFDBA membrane in treatment of infrabony osseous defect showed more defect fill followed by T- PRF along with DFDBA membrane.
