Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The main objective of periodontal treatment is to heal the inflammatory tissue, to eliminate unhealthy periodontal pockets, and to reduce the number of pathogenic bacteria. The traditional treatment of chronic periodontitis is debridement performed with hand tools and ultrasonic devices. However, in deep pockets, which are difficult to access, mechanical root surface debridement is not sufficient to remove the biofilm via root instrumentation.
The regeneration of the periodontium aims at the reconstitution of the periodontal ligament, alveolar bone, and cementum. Platelet concentrates have gained popularity in regenerative periodontal therapy due to their autologous nature. Their regenerative potential is associated with growth factors such as TGFβ-1, PDGF, EGF, IGF-I, and VEGF, stimulate cell proliferation and regulate matrix remodeling and angiogenesis. Growth factors are naturally occurring proteins that regulate cell growth and development. They also modulate cell proliferation, migration, extracellular matrix formation and other cellular functions in epithelization. In addition, some growth factors may function as cell differentiation factors. These functions of the growth factors support epithelization following surgical periodontal treatment and reduce postoperative pain and swelling with their anti-inflammatory properties. Furthermore, studies have reported their antibacterial potentials.
Different platelet concentrates such as platelet-rich plasma (PRP) and platelet-rich fibrin (PRF) are obtained when whole blood is centrifuged at different speeds and for different durations. When the literature is reviewed, it is seen that these platelet concentrates are frequently used in regenerative therapies in dentistry. In 2010, Sohn et al. obtained autologous fibrin glue (AFG), an injectable platelet concentrate, by centrifuging venous blood for two minutes in a special centrifuge device (Medifuge, Silfradent, Italy; 2400-2700 rpm). AFG is used, by mixing it with bone grafts, in the production of sticky bone, which could be an alternative to titanium mesh and bone block procedures that enable grafts to remain more stable in defects.
It was found in the literature review that studies on AFG, which is a second-generation platelet concentrate, are limited in number. It was also found that these studies were conducted on sticky bone, obtained by mixing AFG with bone grafts, and there are no studies in which AFG is used alone to treat periodontal diseases. The purpose of this study is to investigate the effect of AFG, an injectable platelet concentration, on clinical parameters in the nonsurgical treatment of chronic periodontitis.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Two random split-mouth groups were formed among the patients. One side of each patient's mouth was administered AFG following SRP (test group), while the other side of the same patient's mouth was administered a placebo drug (control group).
The following periodontal parameters were evaluated in all patients before and after SRP at the 1st, 3rd, and 6th months: probing depth (PD), clinical attachment level (CAL), plaque index (PI), gingival index (GI), and bleeding on probing (BOP) index. Measurements were performed using a Williams probe (Hu-Friedy, Chicago, IL, USA) for all teeth except for the third molars, in 4 regions (mesiobuccal, midbuccal, distobuccal, midlingual) for PI and GI and in 6 regions (mesiobuccal, midbuccal, distobuccal, mesiolingual, midlingual, distolingual) for PD, CAL, and BOP. Clinical attachment level was measured from the enamel-cement border. Following the initial measurement, the regions with ≥5 mm pocket depth were determined. Measurements were performed only in these regions in the 1st, 3rd, and 6th months. The initial pocket depth was considered within two subgroups as regions with 5-6 mm pocket depth and regions with ≥7 mm pocket depth.
Venous blood from each patient (9 mL) was transferred into a tube without any anticoagulant. Following the protocol recommended by Sohn et al., the venous blood collected in the tube was centrifuged in a special centrifuge machine (Medifuge, Silfradent, Italy). The AFG at the top of the tube was collected using an injector.
Nonsurgical periodontal treatments of the patients were completed in two sessions by a periodontology expert.
In the first session, the supragingival calculus was removed, and patients were given oral hygiene training and encouragement. In the second session, the SRP procedure was performed under local anesthesia in the regions in which there were periodontal pockets of ≥5 mm in the quadrants considered as the control and test groups. The test group was administered AFG using a blunt dental injector in the subgingival region, as an adjunct to SRP, while the control group was administered the placebo.
