WaveOne Gold, ProTaper Gold, Reciproc Blue, ProTaper Next, WaveOne and ProTaper files were selected to compare the phase transformation behaviors and mechanical properties of nickel-titanium (NiTi) rotary files after gold heat and blue heat treatments. The reverse transformation finishing point temperatures of WaveOne Gold, ProTaper Gold, ProTaper Next and WaveOne were higher than those of the other two instruments investigated. At a deflection of 0.5 mm, the loads were significantly varied except for ProTaper Next and ProTaper Gold. At a deflection of 3.0 mm, the loads of Reciproc Blue and WaveOne Gold were significantly varied compared to WaveOne and ProTaper. Cycles to failure were reduced in the order of WaveOne Gold, Reciproc Blue, ProTaper Gold, ProTaper Next, WaveOne and ProTaper. NiTi instruments after gold heat and blue heat treatments exhibited significantly higher bending properties and cyclic fatigue resistances, representing an improved performance over traditional and M-wire instruments.

选择WaveOne Gold，ProTaper Gold，Reciproc Blue，ProTaper Next，WaveOne和ProTaper锉刀，比较金热处理和蓝光热处理后镍钛（NiTi）旋转锉刀的相变行为和机械性能。WaveOne Gold，ProTaper Gold，ProTaper Next和WaveOne的反向转变终点温度高于其他两个研究仪器的温度。在0.5 mm的挠度下，除了ProTaper Next和ProTaper Gold以外，负载都发生了显着变化。在3.0 mm的挠度下，与WaveOne和ProTaper相比，Reciproc Blue和WaveOne Gold的负载变化很大。故障周期按WaveOne Gold，Reciproc Blue，ProTaper Gold，ProTaper Next，WaveOne和ProTaper的顺序减少。
