The purpose of this study is to evaluate the effectiveness of beta tri-calcium phosphate plus calcium sulfate mix, with or without platelet rich fibrin in reducing probing periodontal pockets clinically and defect depths radiographically, while increasing clinical attachment levels to reconstruct intrabony defects in human clinical trials. Materials and Methods: Sixteen participants with periodontal intrabony defects ≥ 5 mm were divided into two equal groups. The first eight intrabony defects in study group received platelet rich fibrin mixed with EthOss ®; while the eight remaining intrabony defects in control group were reconstructed only with EthOss® synthetic bone substitute. Freidman ANOVA and Mann-Whitney tests were chosen for intra-group and inter-group comparisons, respectively. Results: Final outcomes revealed statistically significant decrease in periodontal pocket depth and defect depth values (P ˂ 0.05) with a statistically significant clinical attachment level gain in study and control groups. Precisely, mean values of all measured categories were greater in study rather than control group participants, as confirmed clinically by William’s probe and radiographically by cone-beam computed tomography at 6 months after surgery. Conclusion: Adding PRF to β-TCP plus CS is highly effective in inducing new periodontal soft and hard tissue synthesis resulting in better clinical and radiographic outcomes when surgically incorporated in periodontal intrabony defect(s).
