Brief Summary

Chronic periodontitis is an inflammatory and polymicrobic disease characterized by the irreversible loss of alveolar bone and connective tissue attachment of the teeth. Chronic periodontitis is the most prevalent type of periodontitis and it is seen in the great majority of the adult population. 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.

Outcome Measures

Primary Outcomes (2)

  • change of pocket depths (PD) in millimeters at different time points

    Measurements were performed using a Williams probe (Hu-Friedy, Chicago, IL, USA) for all teeth except for the third molars, in 6 regions (mesiobuccal, midbuccal, distobuccal, mesiolingual, midlingual, distolingual) for PD.

    Pocket depths were evaluated in all patients at baseline and after SRP at the 1st, 3rd, and 6th months

  • change of clinical attachment levels (CAL) in millimeters at different time points

    Measurements were performed using a Williams probe (Hu-Friedy, Chicago, IL, USA) for all teeth except for the third molars, in 6 regions (mesiobuccal, midbuccal, distobuccal, mesiolingual, midlingual, distolingual) for CAL.

    clinical attachment levels were evaluated in all patients at baseline and after SRP at the 1st, 3rd, and 6th months

Secondary Outcomes (3)

  • change of bleeding on probing(BOP) scores in % at different time points

    bleeding on probing scores were evaluated in all patients at baseline and after SRP at the 1st, 3rd, and 6th months

  • change of gingival index(GI) scores in levels at different time points

    gingival index scores were evaluated in all patients at baseline and after SRP at the 1st, 3rd, and 6th months

  • change of plaque index(PI) scores in levels at different time points

    plaque index scores were evaluated in all patients bt baseline and after SRP at the 1st, 3rd, and 6th months

Interventions

The purpose of this study was to investigate effects of autologous fibrin glue (AFG) which was an injectable platelet concentration, on clinical parameters in the nonsurgical treatment of chronic periodontitis.Seventy-two quadrants from 18 patients included in the study and divided into 2 random split-mouth groups. Control group included 631 sites (SRP+Placebo) and AFG group included 682 sites (SRP+AFG). Both groups divided into two subgroups according to initial pocket depth (PD:5-6mm and PD≥7mm).The test group was administered AFG using a blunt dental injector in the subgingival region, as an adjunct to SRP Clinical periodontal parameters including PD, clinical attachment level (CAL), bleeding on probing (BOP), gingival index (GI) and plaque index (PI) were collected at the 1st, 3rd, and 6th months.
