Özet:

 Aim: The aim of this study was to compare the cyclic fatigue resistance of T-Endo Mis rotary system NiTi nickel titanium files in static and dynamic test setups. Material and Method: In this study, ten T-Endo Mis nickel-titanium canal files were used until fracture in static and dynamic test setups with a curvature angle of 60 and a curvature radius of 5 mm in stainless steel artificial canals at temparature of 35  2C. Fracture times were visually and audibly detected and recorded with a digital chronometer. The lengths of the fractured fragments were precisely measured with a digital caliper. After evaluating the normal distribution of data with the Kolmogorov-Smirnov test, an independent sample t-test was used to analyze the time until fracture, and the Mann-Whitney U test was used to analyze the lengths of the fractured fragments. Tests were conducted in SPSS software V.21, IBM, IL, USA with a 5 significance threshold. Results: After the conformity of the data to the normal distribution was tested, it was found that they were statistically similar as a result of comparing the time elapsed until decapitation and the broken part lengths between the two test models. p  0.05. Conclusion: In this study, it was found that the static and dynamic cyclic fatigue resistances of T-Endo Mis NiTi files are similar.

 Amaç: Bu çalışmanın amacı, T-Endo Mis döner sistem NiTi nikel-titanyum eğelerin döngüsel yorgunluk dayanımlarını statik ve dinamik test düzeneklerinde karşılaştırmaktır. Gereç ve Yöntem: Bu çalışmada onar adet T-Endo Mis nikel titanyum kanal eğeleri, statik ve dinamik test düzeneklerinde 60 kurvatür açısı ve 5 mm kurvatür yarıçapına sahip paslanmaz çelik yapay kanallar içerisinde 35  2 C sıcaklıkta kırılıncaya kadar kullanıldı. Kırılma zamanları görsel ve işitsel olarak tespit edilip dijital kronometre ile kaydedildi. Kırılan parça uzunlukları dijital kumpas ile ölçüldü. Verilerin normal dağılımı Kolmorogov-Smirnov testi ile değerlendirildikten sonra bağımsız örneklem t-testi kırılana kadar geçen süreyi, Mann-Whitney U testi ise kırık parça uzunluklarını analiz etmek için kullanıldı. Testler SPSS programında V.21, IBM, IL, ABD 5 anlamlılık eşiği ile yapıldı. Bulgular: Verilerin normal dağılıma uygunluğu test edildikten sonra, kırılana kadar geçen süre ve kırık parça uzunluklarının iki test modeli arasında karşılaştırılması sonucu istatistiksel olarak benzer oldukları tespit edildi p0.05 Sonuç: Bu çalışmada T-Endo Mis NiTi eğelerin statik ve dinamik döngüsel yorgunluk dayanımlarının benzer olduğu ve kırık parça uzunluklarının arasında istatiksel olarak anlamlı bir fark olmadığı bulunmuştur.
