这篇研究的目的是通过micro-CT评估和比较ProGlider (PG; Dentsply-Sirona, Ballaigues, Switzerland), WaveOne Gold Glider (WOGG; Dentsply-Sirona)和R-Pilot (RP; VDW, Munich, Germany)锉系统的传递性和定心率变化以及结构模型指数(SMI)、根管表面积和体积（在下颌第一

这篇研究的目的是通过micro-CT评估和比较ProGlider (PG； Dentsply-Sirona， Ballaigues， Switzerland)， WaveOne Gold Glider (WOGG； Dentsply-Sirona)和R-Pilot (RP； VDW， Munich， Germany)锉系统的传递性和定心率变化以及结构模型指数(SMI)、根管表面积和体积（在下颌第一磨牙中等弯曲的近中根创建顺滑通道后）的变化。这篇研究使用24颗含有2个独立近中根管并且中等(10°-20°)弯曲的下颌第一磨牙作为观察对象。在micro-CT扫描完后将牙齿分为3组：PG， WOGG和RP (n = 10/each group)，并进行顺滑通道的预备。根管预备完成后，通过micro-CT影像分析根管预备后的体积、表面积、SMI、传递性以及它们在根尖、根中和根冠1/3处的定心率变化。数据通过1-way analysis of variance和Kruskal-Wallis检验进行统计学评估，显著性水平设置为5% (P < .05)。结果显示，WOGG和RP锉系统在根管所有部
