In this study, the possible effect of blood group distribution on the content of blood biomaterial was investigated. 64 volunteers were included in the study. Various parameters were evaluated. As a result, it was concluded that blood group distribution does not affect blood biomaterial content.
The aim of this split-mouth, randomized, and controlled study was to compare open flap debridement (OFD) alone against OFD with autogenous Titanium-prepared platelet-rich fibrin (OFD+ T-PRF) combined in treating intrabony defects (IBD). Subjects were 20 systemically healthy patients with chronic periodontitis according to 2017 World Workshop. Bilateral operation sites in patients (40 sites) were randomly selected for OFD alone or OFD+ T-PRF combined. Clinical parameters (probing depth (PD), relative attachment level (RAL), and gingival marginal level(GML)), radiographic parameters (intrabone defects (IBDs) and periodontal bone support (PBS)), and growth factors levels (GFL) in gingival crevicular fluid (GCF) (platelet-derived growth factors (PDGF-BB), fibroblast growth factors (FGF-2), relative ratio of receptor activator nuclear factor kappa-B (RANKL)/osteoprotegerin (OPG)) were analyzed. The Wilcoxon signed-rank test, the Student's t-test, the two way ANOVA, and the Tukey post hoc test were used for statistical analysis.

All surgical procedures were performed by the second periodontist. 0.12% Chlorhexidine digluconate (CHX) rinse for intraoral antisepsis and a povidone iodine solution was used for extraoral antisepsis. After local anesthesia (2% lidocaine with epinephrine 1:100,000/ Astra, Westbrough, MA) was applied, the full thickness trapezoidal flap was raised large enough to provide adequate view of the defect area. Subgingival debridement and root planning were performed with the use of area-specific curets (Gracey curets, Hu-Friedy), and granulation tissue was removed The IBD area in the control group was closed without applying any material. Then mucoperiosteal flaps were repositioned with sutured with 4/0 monoprolene sutures.

Subgingival debridement and root planning were performed with the use of area-specific curets (Gracey curets, Hu-Friedy), and granulation tissue was removed (Figure 2a). The blood supply of the defect areas was taken into account. At the test site, IBDs were filled with T-PRF and T-PRF membranes were adapted over the defects both buccally and lingually, in addition to OFD (Figure 2b). Then mucoperiosteal flaps were repositioned with sutured with 4/0 monoprolene sutures.
