Abstract
Objectives: The purpose of present study was to evaluate the incidence of dentinal micro-cracks observed after the use of ProTaper Gold (PTG), WaveOne Gold (WOG), OneShape New Generation (OSNG), K3XF nickel-titanium (NiTi) instrumentation systems.
Materials and Methods: Sixty extracted human mandibular first molars were randomly assigned to four groups (n = 15). The root canals were instrumented with PTG, WOG, OSNG, and K3XF systems. The cross-sectional images of the roots were screened using high-resolution micro-computed tomography imaging before and after preparation to detect the presence of dentinal cracks.
Results: Although there was no statistically significant difference between PTG and WOG systems, WOG caused lesser micro-crack among all groups. K3XF showed statistically fewer cracks than OSNG. K3XF and OSNG systems caused statistically more dentinal micro-cracks than both Gold systems. WOG and PTG systems caused lesser micro-cracks formation among the systems evaluated in present study. Both Gold systems may be preferred as safer to minimize micro-cracks during root canal treatments.
Conclusions: All used systems have caused different degrees of crack formations. Furthermore, WOG and PTG systems have shown superior features in terms of creating dentinal cracks according to OSNG, and K3XF systems.

Abstract
Amaç: Bu çalışmanın amacı, ProTaper Gold (PTG), WaveOne Gold (WOG), OneShape Yeni Nesil (OSNG), K3XF nikel-titanyum (NiTi) enstrümantasyon sistemlerinin kullanımından sonra gözlenen dentin mikro çatlaklarının insidansını değerlendirmektir. .
Gereç ve Yöntem: Altmış adet çekilmiş insan mandibular birinci molar dişi rastgele dört gruba ayrıldı (n = 15). Kök kanalları PTG, WOG, OSNG ve K3XF sistemleri ile enstrümante edildi. Köklerin kesit görüntüleri, dentin çatlaklarının varlığını tespit etmek için hazırlıktan önce ve sonra yüksek çözünürlüklü mikro bilgisayarlı tomografi görüntüleme kullanılarak tarandı.
Bulgular: PTG ve WOG sistemleri arasında istatistiksel olarak anlamlı bir fark olmamasına rağmen, WOG tüm gruplar arasında daha az mikro-çatlamaya neden oldu. K3XF, OSNG'den istatistiksel olarak daha az çatlak gösterdi. K3XF ve OSNG sistemleri, her iki Gold sisteminden istatistiksel olarak daha fazla dentin mikro çatlaklarına neden oldu. WOG ve PTG sistemleri, bu çalışmada değerlendirilen sistemler arasında daha az mikro çatlak oluşumuna neden olmuştur. Kanal tedavileri sırasında mikro çatlakları en aza indirmek için her iki Gold sistemi de daha güvenli olarak tercih edilebilir.
Sonuçlar: Kullanılan tüm sistemler farklı derecelerde çatlak oluşumlarına neden olmuştur. Ayrıca WOG ve PTG sistemleri, OSNG ve K3XF sistemlerine göre dentin çatlakları oluşturma konusunda üstün özellikler göstermiştir.
