GÝRÝÞ ve AMAÇ: Bu çalýþmanýn amacý, kök kanal þekillendirilmesi sýrasýnda kullanýlan ProTaper Next, WaveOne Gold ve One Shape New Generation döner alet sistemlerinin kök dentin kýrýlma direnci üzerindeki etkilerini incelemektir.
YÖNTEM ve GEREÇLER: Seksen adet çekilmiþ insan alt premolar diþi rastgele 4 gruba ayrýldý (n=20). Kök kanallarý el aletleri, OSNG, PTN ve WOG rotary sistemleri ile enstrümante edildi. Elements Free Obturasyon sistemi ile doldurulan kök kanallarýna üniversal test cihazý ile 1 mm/dk kuvvet uygulandý. Kýrýk oluþumuna uygulanan maksimum kuvvet Newton cinsinden ayrý ayrý kaydedilmiþtir.
BULGULAR: WOG ile OSNG gruplarý arasýnda istatistiksel olarak anlamlý bir fark bulunmamýþtýr (P>.05). PTN grubu, OSNG ve WOG gruplarýyla karþýlaþtýrýldýðýnda istatistiksel olarak daha düþük kök dentin kýrýlma direnci deðerleri gösterdi (P<.05).
TARTIÞMA ve SONUÇ: Kök dentin direnci ile ilgili olarak, WOG sistemi kök kanal tedavileri sýrasýnda kök dentin kýrýlma direnci açýsýndan daha güvenli bir sistem olarak tercih edilebilir.

Anahtar Kelimeler: Kýrýlma Direnci, Döner eðe sistemleri, Elements Free Obturasyon Sistemi

INTRODUCTION: The aim of this study was to examine the effects of ProTaper Next, WaveOne Gold, and One Shape New Generation rotary instrument systems used on root dentin fracture resistance during root canal preparation.
METHODS: Eighty extracted human lower premolar teeth were randomly divided into 4 groups (n=20). The root canals were instrumented with hand instruments, OSNG, PTN and WOG rotary systems. The root canals that were filled with Elements Free Obturation System were subjected to force (1 mm/min) with a universal tester. The maximum force applied to fracture formation was recorded in Newtons separately.
RESULTS: There was no statistically significant difference between the WOG and the OSNG groups (P>.05). The PTN group showed statistically lower root dentin fracture resistance values comparing the OSNG and the WOG groups (P<.05).
DISCUSSION AND CONCLUSION: Regarding the root dentin resistance, the WOG system may be preferred as safer system in terms of root dentin fracture resistance during root canal treatments. For the diagnosis and treatment of TMDs, patients are referred to the clinic for, mostly by orthodontists and otolaryngologists.
