Abstract

Introduction: The aim of our study is to comparatively analyze the canal cyclic fatigue resistance of widely used rotary file systems, including EndoArt Touch Gold (ETG), Perfect MTF Plus Gold (PPG), Fanta V-Taper Gold (FVG), and ProTaper Next (PTN).

Methods: Stainless steel canals with a 60° angle and a 3-mm curvature radius were specially prepared. The canals were shaped with each rotary file system and tested for resistance using a cyclic fatigue testing apparatus. The number of fracture cycles (NFC; K file tip separation) was measured. Data were analysed by one-way ANOVA and post hoc LSD tests.

Results: PTN and PPG rotary file systems exhibited the highest NFC. The NFC value for PTN was 589 ± 63, and for PPG, it was 507 ± 51.

Conclusion: The results of this study demonstrate that rotary file systems such as PTN and PPG exhibit higher cyclic fatigue resistance. ETG and FVG rotary file systems also possess generally acceptable cyclic fatigue resistance levels.

在静态测试模型中评估新型仿制仪器的循环抗疲劳性

简介：我们的研究旨在比较分析广泛使用的旋转锉系统（包括EndoArt Touch Gold (ETG)、Perfect MTF Plus Gold (PPG)、Fanta V-Taper Gold (FVG)和ProTaper Next (PTN)）的根管循环疲劳抗力：专门制备了角度为 60°、曲率半径为 3 毫米的不锈钢牙道。使用每种旋转锉系统对牙槽骨进行塑形，并使用循环疲劳测试仪器对其进行耐受性测试。测量了断裂循环次数（NFC；K 锉尖分离）。通过单因素方差分析和事后 LSD 检验对数据进行分析：结果：PTN 和 PPG 旋转锉系统的 NFC 值最高。结果：PTN 和 PPG 旋转锉系统的 NFC 值最高，PTN 为 589 ± 63，PPG 为 507 ± 51：研究结果表明，PTN 和 PPG 等旋转锉系统具有更高的抗循环疲劳性能。ETG 和 FVG 旋转锉系统也具有一般可接受的抗循环疲劳水平。

期刊介绍： Applied Bionics and Biomechanics publishes papers that seek to understand the mechanics of biological systems, or that use the functions of living organisms as inspiration for the design new devices. Such systems may be used as artificial replacements, or aids, for their original biological purpose, or be used in a different setting altogether.
