AIM
The purpose of this comparative study was to investigate the cyclic fatigue resistance (CFR) of two different rotary endodontic file systems, namely, TruNatomy and ProTaper Next filing systems.
MATERIAL AND METHODS
A stainless steel artificial canal with a 60° curvature angle and a 5 mm radius of curvature was used to simulate clinical settings to carry out the test. Twenty ProTaper Next X2 files and 20 TruNatomy Prime files were used to run a total of forty instruments until a fracture occurred, and the amount of time it took for the fracture to occur was taken into account. The files were driven by an endodontic motor set when the settings were adjusted according to the manufacturer's recommendations. A digital meter was employed to record the duration until fracture occurrence, thus ensuring precision.
RESULTS
The TruNatomy files had a larger mean cycle fatigue life, which indicates that they have a higher resistance.
CONCLUSIONS
Given the constraints of this testing, the CFR of TruNatomy files was found to be significantly higher than that of ProTaper Next files.
目的
本比较研究的目的是调查两种不同的旋转根管锉系统，即TruNatomy和ProTaper Next锉系统的循环疲劳抗力（CFR）。
材料与方法
使用一个曲率角度为60°、曲率半径为5毫米的不锈钢人工根管来模拟临床环境进行测试。使用20支ProTaper Next X2锉和20支TruNatomy Prime锉，总共运行40支器械，直到发生折断，并记录折断发生所需的时间。当根据制造商的建议调整设置时，锉由根管马达驱动。使用数字仪表记录直至折断发生的持续时间，从而确保精度。
结果
TruNatomy锉具有更大的平均循环疲劳寿命，这表明它们具有更高的抗力。
结论
鉴于本测试的限制，发现TruNatomy锉的CFR显著高于ProTaper Next锉。
