In the present study, we compared the cyclic fatigue resistance (CFR) of Reciproc Blue, WaveOne Gold, and SmartTrack files in curved artificial canals.
Ninety new Reciproc Blue R25, WaveOne Gold Primary, and SmartTrack X1 files were tested in artificial canals with 45° and 60° angles of curvature. CFR was determined by recording the time to fracture in the artificial canals. Two-way analysis of variance was used to analyze the data.
In the canal with a 45° angle of curvature, no significant differences were observed amongst Reciproc Blue, WaveOne Gold, and SmartTrack (P > .05). In the canal with a 60° angle of curvature, Reciproc Blue and SmartTrack had a greater CFR than WaveOne Gold (P < .05); there was no significant difference between the Reciproc Blue and SmartTrack files (P > .05).
The results of the present study showed that Reciproc Blue and SmartTrack files exhibited greater CFR than WaveOne Gold only in canals with a 60° angle of curvature.
在本研究中，我们比较了Reciproc Blue、WaveOne Gold和SmartTrack锉在弯曲人工根管中的抗循环疲劳性能（CFR）。
九十支全新的Reciproc Blue R25、WaveOne Gold Primary和SmartTrack X1锉在曲率为45°和60°的人工根管中进行测试。通过记录在人工根管中折断的时间来确定CFR。采用双向方差分析对数据进行分析。
在曲率为45°的根管中，Reciproc Blue、WaveOne Gold和SmartTrack之间未观察到显著差异（P >.05）。在曲率为60°的根管中，Reciproc Blue和SmartTrack的CFR高于WaveOne Gold（P <.05）；Reciproc Blue和SmartTrack锉之间无显著差异（P >.05）。
本研究结果表明，仅在曲率为60°的根管中，Reciproc Blue和SmartTrack锉的CFR高于WaveOne Gold。
