TY - JOUR T1 - Post Endodontik Restorasyonlarda Kullanılan Post-Kor Sistemlerinin Kırılma Dayanımı Açısından Değerlendirilmesi TT - Comparasion of Fracture Strength of Post-Core Systems used in Post-Endodontic Restorations AU - Savaş, Deniz AU - Maden, Murat PY - 2025 DA - April Y2 - 2025 DO - 10.22312/sdusbed.1473407 JF - Süleyman Demirel Üniversitesi Sağlık Bilimleri Dergisi PB - Süleyman Demirel University WT - DergiPark SN - 2146-247X SP - 8 EP - 16 VL - 16 IS - 1 LA - tr AB - Amaç: Bu çalışma ile fazla madde kaybına uğramış endodontik tedavili dişlerin restorasyonunda kullanılan farklı post-kor sistemlerini kırılma dayanımları açısından karşılaştırmak amaçlandı.Gereç ve Yöntem: Çalışmada çekilmiş, tek köklü, tek kanallı 45 adet kronu uzaklaştırılmış insan alt premolar dişi kullanıldı. Dişlere kök kanal tedavisi uygulandıktan sonra kök kanallarına post yuvası açıldı. Dişler 3 gruba ayrılarak Grup 1’e cam fiber post-kompozit kor, Grup 2’ye kompozit post-kor, Grup 3’e ise lityum disilikat post-kor hazırlandı. Daha sonra dişlere universal test cihazında kuvvet uygulanarak kırılma dayanımı değerleri tespit edildi ve dişlerde oluşan kırık tipleri incelendi. Verilerin istatistiksel analizinde Bonferroni ve Shapiro-Wilk testleri kullanıldı. Bulgular: Elde edilen sonuçların istatistiksel değerlendirmesi sonucunda grupların kırılma dayanımı değerleri arasında istatistiksel olarak anlamlı bir farklılık tespit edildi (p KW - Fiber post KW - Kırılma dayanımı KW - Post-kor N2 - Objective: The aim of this study was to compare the fracture strength of different post-core systems used in the restoration of endodontically treated teeth with excessive material loss.Materials and Methods: Forty-five single and straight-root decoronated human mandibular premolar teeth were used. After root canal treatment, post space preparation have been made. Teeth were randomly divided into three groups : Group 1 glass fiber post-composite core, Group 2 composite post-core, Group 3 lithium disilicate post-core.For all groups, fracture resistance (N) value was measured and recorded using a universal testing machine. The types of fractures in the teeth were examined. Bonferroni and Shapiro-Wilk tests were used for statistical analysis of the data. Results: As a result of the statistical evaluation of the results obtained, a statistically significant difference was found between the fracture strength values of the groups (p CR - 1.
