Objectives:
This research intended to compare and evaluate the effectiveness of titanium-prepared platelet-rich fibrin (T-PRF) over demineralized freeze-dried bone allograft (DFDBA) in treating intra-bony defects based on the clinical and radiographic criteria.
Methods:
This is a prospective randomized controlled, single-blinded split-mouth study where 15 patients with 30 intrabony defects were included. Subjects were randomly divided into T-PRF and DFDBA groups respectively. Plaque index (PI), Gingival index (GI), Probing pocket depth (PPD), Relative- clinical attachment- level (R-CAL), Defect depth, Linear amount of bone fill, Percentage of bone fill, Defect angle were assessed at baseline, 3, 6, and 9 months. For intra- and inter-group comparisons, paired and unpaired t-tests were executed. P<0.05 was set as statistically significant.
Results:
There were statistically significant differences (P<0.05) in clinical and radiographic parameters in both T-PRF and DFDBA groups from baseline values to 9 months in intragroup comparisons. However, on intergroup comparison, no statistical significance was seen.
Conclusion:
The clinical parameters and radiographic outcomes showed marked improvement at 9 months with both T-PRF and DFDBA in the treatment of intrabony defects from baseline values.
Clinical Relevance:
T-PRF has shown favorable results that are comparable to DFDBA for the treatment of intrabony periodontal defects.
