Bağlama özelliği olan bir kanal dolgu materyali ile veya farklı fiber post tipleri ile restore edilen endodontik tedavili köklerin kırılma dirençlerinin in vitro incelenmesi

Bu çalışmanın amacı fiber postlar ve kökkanal duvarlarına bağlanma özelliği olan bir kökkanal dolgu materyali ile doldurulmuş köklerin k›r›lma direncini karş›laşt›rmakt›r. Bu çal›şma için yeni çekilmiş 40 adet maksiller kanin diş seçildi ve 4 gruba ayr›ld›. Grup 1’de 10 adet kanal Resilon ve Epiphany pat› ile dolduruldu. Grup 2’de 10 adet kanal AH Plus ve gütta perka ile dolduruldu ve quartz-fiber postlar simante edildi. Grup 3’te 10 adet kanal AH Plus ve gütta perka ile dolduruldu ve karbon fiber postlar simante edildi. Grup 4’te 10 adet kanal AH Plus ve gütta perka ile dolduruldu. K›r›lma direnci testleri bir Universal test cihaz› ile yap›ld›. Grup 1 ve 4 P

In Vitro Fracture Resistance of Endodontically Treated Roots Filled With a Bonded Filling Material or Different Types of Fiber Posts

The aim of this study was to compare the fracture resistance of roots filled with a bonded material or fiber posts. 40 freshly extracted human maxillary canine teeth were selected and divided into fourgroups. The 10 roots in Group 1 were filled withResilon and Epiphany sealer . The 10 roots inGroup 2 were filled with AH Plus and gutta-perchaand then quartz-fiber posts were placed. The 10roots in Group 3 were filled with AH Plus andgutta-percha and then carbon-fiber posts werecemented. The 10 roots in Group 4 were filled withAH Plus and gutta-percha. Tests for fracturestrength were performed using a Universal Testmachine. The difference between Group 1 and 4 P
