Amaç: Bu çalışmada, epoksi-rezin içerikli kanal patı ile karşılaştırmalı olarak tek başına veya guta-perka ile birlikte kullanılan kalsiyum silikat içerikli kanal dolgu patlarının köklerin kırılma direnci üzerindeki etkisini değerlendirmek amaçlanmıştır. Gereç ve Yöntemler: Altmış adet tek köklü, tek ve düz kanallı mandibular premolar diş seçilmiştir. Diş kökleri 13 mm kalacak şekilde kron kısımları uzaklaştırılmıştır. Örnekler rastgele 6 gruba ayrılmıştır (n=10). Grup 1 (negatif kontrol): Preparasyon yapılmış ancak kanal dolgusu yapılmamıştır. Grup 2 (pozitif kontrol): AH Plus patı ve tek kon tekniği ile kanallar doldurulmuştur. Grup 3a: GuttaFlow Bioseal (GFB) patı kor materyali olmadan (bulkfill) kullanılmıştır. Grup 3b: GFB patı ve tek kon tekniği ile kanallar doldurulmuştur. Grup 4a: Tech Biosealer (TB) patı kor materyali olmadan kullanılmıştır. Grup 4b: TB patı ve tek kon tekniği ile kanallar doldurulmuştur. Akrilik rezine gömülen dişlerin kırılma direnci Universal Test Cihazı ile değerlendirilmiştir. Kırılmaya neden olan maksimum yük değerleri belirlenmiş ve Newton cinsinden (maksimum-kuvvet) kaydedilmiştir. Sonuçlar tek yönlü varyans analizi ve Tukey çoklu karşılaştırma testi kullanılarak p<0,05 anlamlılık düzeyinde istatistiksel olarak analiz edilmiştir. Bulgular: Kökleri kırmak için gereken en zayıf kuvvet negatif kontrol grubunda görülürken, en yüksek kuvvet TB-Bulkfill grubunda görülmüştür (p<0,05). GFB ve TB kanal patları bulkfill olarak kullanıldığında tek kon tekniğine kıyasla anlamlı olarak daha yüksek kırılma dayanımı elde edilmiştir (p<0,05). Tek kon tekniğinin kullanıldığı gruplarda TB patı, GFB ve AH Plus'a kıyasla daha yüksek kırılma dayanımı göstermiştir (p<0,05). Sonuç: Tüm kök kanal dolgu patları, prepare edilmiş kök kanallarının kırılmaya karşı direncini artırmıştır. GFB ve TB patları bulkfill olarak kullanıldığında, tek kon tekniğine kıyasla daha yüksek kırılma direnci göstermiştir.

Objective: This study was aimed to evaluate the influence of calcium silicate-based sealers, with or without gutta-percha, on fracture resistance of roots, in comparison with epoxy-resin basedsealer. Material and Methods: Sixty single rooted, single and straight canal mandibular premolar teeth were selected. The samples were decoronated to obtain roots with a standardized length of 13 mm. The samples were randomly divided into 6 groups (n=10). Group 1 (negative control): Root canals were prepared and left unfilled. Group 2 (positive control): Root canals were filled with AH Plus and single cone technique (SC). Group 3a: GuttaFlow Bioseal (GFB) was used without a core material (bulkfill). Group 3b: Root canals were filled with GFB and SC. Group 4a: Tech Biosealer (TB) was used without a core material. Group 4b: Root canals were filled with TB and SC. The fracture resistance of teeth embedded in acrylic resin wasevaluated with the Universal Test Machine. The maximum load values that cause fracture in the samples were determined and recorded in Newtons. The results were statistically analyzed at p<0.05 significance level using one-way analysis of variance and Tukey multiple comparison test. Results: The minimum and highests forces were seen in the negative control and the TB-Bulkfill groups, respectively (p<0.05). When GFB and TB sealers were used as bulkfill, higher fracture resistance were obtained compared to the SC. Conclusion: All root canal sealers examined in this study increased the fracture resistance of prepared root canals. When GFB and TB were used as bulkfill, showed higher fracture resistance compared to SC.
