The impact of 5.25 percent NaOCL on the resistance offered by TruNatomy, Hero Gold and ProtaperGold against cyclic fracture as against the treatment of NiTi rotary files with distilled water is of interest to dentists. Inside the stainless steel blocks, man-made canals were created for the purpose of testing the cyclic fatigue. 60 endodontic files were taken as study specimens. It was observed that values of number of cycles to fracture in NaOCl among three file systems were in the order of TruNatomy (1053.50 ± 134.81)>Hero Gold (652.66 ± 58.66) > ProtaperGold (494.50 ± 47.69). The TruNatomy file system reflected greatest cyclic fatigue resistance. It was also found that cyclic fatigue resistance in NiTi rotary files studied here is not hampered by 5.25% NaOCl.
5.25%次氯酸钠（NaOCl）对TruNatomy、Hero Gold和ProtaperGold抵抗循环断裂的影响，与用蒸馏水冲洗镍钛旋转锉的处理方式相比，是牙医们感兴趣的。在不锈钢块内部，为测试循环疲劳而创建了人工根管。选取60支根管锉作为研究标本。观察到，在三种锉系统中，NaOCl环境下的断裂循环次数值顺序为：TruNatomy（1053.50 ± 134.81）> Hero Gold（652.66 ± 58.66）> ProtaperGold（494.50 ± 47.69）。TruNatomy锉系统表现出最强的循环疲劳抗性。还发现，此处研究的镍钛旋转锉的循环疲劳抗性不受5.25% NaOCl的影响。
