Abstract :Amaç: Bu çalışmanın amacı, WaveOne insert ignore into journalissuearticles values(Dentsply Maillefer, Ballaigues, İsviçre);, Reciproc insert ignore into journalissuearticles values(VDW, Münih, Almanya); ve Twisted File Adaptive insert ignore into journalissuearticles values(Axis/SybronEndo, Orange, CA, ABD); döner sistem nikel titanyum insert ignore into journalissuearticles values(Ni-Ti); eğelerin çift kurvatürlü insert ignore into journalissuearticles values(S-şekilli); kanallarda döngüsel yorgunluğa bağlı kırılma dirençlerinin karşılaştırılmasıdır. Gereç ve Yöntem: Bu çalışmada 45 adet insert ignore into journalissuearticles values(WaveOne primary, Reciproc R25 ve Twisted File Adaptive M-L1); eğe kullanıldı. Her bir sistemden 15 eğe kırılıncaya kadar çift kurvatürlü insert ignore into journalissuearticles values(S-şekilli); yapay bir kanalda döndürüldü. Kırılıncaya kadar olan tur sayısı hesaplandı ve kırılmış parçaların uzunluğu kaydedildi. Veriler, ANOVA ve Tukey post hoc testleri kullanılarak istatistiksel olarak analiz edildi. İstatistiksel anlamlılık düzeyi p < 0.05 olarak belirlendi. Bulgular: Reciproc R25 eğeleri hem apikal hem de koranal kurvatürde, WaveOne primary ve Twisted File Adaptive M-L1 eğelerine göre döngüsel yorgunluğa karşı daha dirençli bulundu insert ignore into journalissuearticles values( p < 0.05);. WaveOne primary ve Twisted File Adaptive M-L1 eğeleri arasında her iki kurvatürde de istatistiksel olarak anlamlı farklılık saptanmadı insert ignore into journalissuearticles values( p > 0.05);. Bütün gruplar arasında aletlerin kırılmış fragmanlarının uzunluğu istatistiksel olarak benzer bulundu insert ignore into journalissuearticles values( p > 0.05);. Sonuç: Reciproc R25 eğeler, WaveOne primary ve Twisted File Adaptive eğelere göre çift kurvatürlü kanallarda kırılmaya karşı daha dirençli bulundu.

Materials and Methods: Forty five rotary NiTi files insert ignore into journalissuearticles values(WaveOne primary, Reciproc R25 and Twisted File Adaptive M-L1); were used in this study. Fifteen files from each system were rotated in canals with a double curvature until fracture. The number of cycles to fracture was calculated and the length of each fractured fragment was recorded. The data were statistically analysed using ANOVA and Tukey post hoc tests. The statistical significance level was set at p < 0.05. Results: The Reciproc R25 file had higher cyclic fatigue resistance than WaveOne primary and Twisted File Adaptive in the apical and coronal curvatures insert ignore into journalissuearticles values( p < 0.05);. There was no significant distinction in the cyclic fatigue resistance of the WaveOne primary and Twisted File Adaptive files in either the apical or coronal curvature. The length of the fractured part of the instruments was similar among all the groups insert ignore into journalissuearticles values( p > 0.05);. Conclusion: The Reciproc R25 file indicated better cyclic fatigue resistance than WaveOne primary and Twisted File Adaptive in an artificial canal with an S-shape.
