The aim of this study was to measure the fracture resistance of endodontically treated maxillary premolars restored with ormocer,hybrid and nanofill composite resins. Fourty sound, caries-free human maxillary premolar teeth were used. The teeth were endodontically treated and MOD cavities prepared. The prepared teeth were randomly divided into four groups of 10 teeth. Each group was restored with four different restorative materials one ormocer, one nanofill, one hybrid and one high copper amalgam . Copper rings were filled with self-curing polymethylmetacrylate resin and the teeth were placed into resin up to the level of the cementoenamel junction. The copper rings with the teeth were placed into a Universal Testing Machine and the buccal walls were subjected to a slowly increasing compressive force until fracture occurred. The force of fracture of the various groups compared. Statistical analysis was performed by using one way analysis of variance ANOVA .There was no statistically significant difference between the groups. There was no difference in the fracture resistance of endodontically treated teeth following restoration with amalgam and composite restorative materials. Within the limits of this study we can suggest that resins used in this study are good alternative materials to amalgam

Bu çalışmanın amacı amalgam, ormoser,hibrit ve nano dolduruculu kompozit rezinler kullanılarak restore edilen maksiller premolar dişlerin kırılma dirençlerini ölçmektir. Bu çalışmada 40 adet çürüksüz insan maksiller premolar dişi kullanılmıştır. Dişlere kök kanal tedavisi uygulandıktan sonra MOD kaviteler hazırlanmıştır. Hazırlanan dişler her bir grupta 10 diş olmak üzere 4 gruba ayrıldı. Her bir grup farklı restoratif materyalle ormoser, nano dolduruculu kompozit, hibrit kompozit, yüksek bakırlı amalgam restore edildi. Bakır anolar kendinden polimerize olabilen polimetilmetakrilatla doldurulduktan sonra dişler mine sement seviyesine kadar bu anolara gömüldü. Bakır anolar Universal test makinesine yerleştirilerek bukkal duvarlara kırık oluşana kadar yavaşça artan kompresif güç uygulandı. Çeşitli gruplarda kırık oluşturmak için uygulanması gereken kuvvetler karşılaştırıldı. İstatistik analiz tek yönlü varyans analizi ANOVA kullanılarak yapıldı. Gruplar arasında belirgin olarak istatistik bir fark bulunmadı.Amalgam veya kompozitle restore edilmiş endodontik tedavili dişlerin kırılma dirençleri arasında belirgin bir fark bulunmadı. Bu çalışmanın sonuçları dahilinde bu çalışmada kullanılan rezin materyaller amalgam restorasyonlara göre iyi alternatifler olarak tavsiye edilebilir
