Özet:

 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 p0.05. The fracture strength of the teeth in the fiber post-composite core group was significantly lower than the other two groups, while there was no significant difference in fracture strength between the composite post-core and lithium disilicate post-core groups. Restorable fracture types were more common in the fiber post-composite core group, while unrestorable fracture types were more common in the composite post-core and lithium disilicate post-core groups. Conclusion: Within the limitations of this study, in short post applications, the fracture strength of the fiber post-composite core group was lower than the composite post-core and lithium disilicate post-core groups, and the fracture types in the fiber post-composite core group were more restorable.

 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 1e cam fiber post-kompozit kor, Grup 2ye kompozit post-kor, Grup 3e 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 p0,05. Fiber post-kompozit kor grubundaki dişlerin kırılma dayanımı diğer iki gruptan anlamlı olarak düşük çıkarken, kompozit post-kor ve lityum disilikat post-kor grupları arasında kırılma dayanımını açısından fark bulunmadı. Fiber post-kompozit kor grubunda restore edilebilir kırık tipi, kompozit post-kor ve lityum disilikat post-kor gruplarında ise restore edilemez kırık tipleri daha fazla görüldü. Sonuç: Bu çalışmanın sınırları dahilinde, kısa post uygulamalarında, fiber post-kompozit kor grubunun kırılma dayanımı kompozit post-kor ve lityum disilikat post-kor gruplarına göre daha düşük bulundu. Ayrıca fiber post- kompozit kor grubundaki kırık tiplerinin daha restore edilebilir olduğu gözlendi.
