    (Cumhuriyet University Faculty of Dentistry, 2015) Tunali M.; Selek B.; Küçükodaci Z.; Özdemir H.; Koçyiğit I.D.; Aytugar E.; Süer B.T.
    There are many complications associated with a maxillary sinus, during extraction of a maxillary posterior teeth. Root of a tooth which is accidentally pushed into the maxillary sinus is one of the reasons that make up 10% of the dental-sourced maxillary sinusitis. In the literature, although many types of bacteria cause dental-sourced sinus infection, enteric Citrobacter coseri (C. koseri) is a rare factor of maxillary sinusitis. A 34-year-old woman presented to our clinic with pain in the right upper jaw molar teeth region. A displaced tooth root was detected by a panoramic film in an edentulous maxillary first molar region. Surgical removal of the tooth root was undertaken via an open sinus surgery with resolution of symptoms. Green tooth root was analyzed in an anaerobic and aerobic culture in a microbiology laboratory. After 24-hour in 37 °C aerobic incubation time pure gram negative basil colonies were observed. Following the conventional methods colonies also were analyzed with the compact automatic identification system VITEK2, and were detected as C. coseri.

    Clinical application of second generation trombosite concentration
    (2012) Koçyiğit I.D.; Tunali M.; Özdemir H.; Kartal Y.; Süer B.T.
    The therapeutic use of autologous platelet-rich fibrin constitutes a relatively new biotechnology that has been a breakthrough in the stimulation and acceleration of soft-tissue and bone healing. The efficiency of this process lies in the local and continuous delivery of a wide range of growth factors and proteins, mimicking the needs of the physiological wound healing and reparative tissue processes. Platelet-rich fibrin (PRF) belongs to a new generation of platelet concentrates, with simplified processing and without biochemical blood handling. This easy protocol allows the production of leukocyte and platelet-rich fibrin clots starting from autologous blood samples. PRF is used especially in clinical Periodontal and Oral and Maxillofacial Surgery applications. The significance of the PRF is gradually increasing.
