This study compared the quantity of extruded debris after instrumentation with TRUShape 3D Conforming files, TruNatomy files, and the WaveOne Gold reciprocating system.
Fifty-one mesiobuccal canals with severe curvatures (25-40°) were assigned to three equal groups according to the rotary system used for preparation, either TRUShape, TruNatomy, or WaveOne Gold files. The extruded debris was collected in pre-weighed glass vials. The data were statistically analyzed using a one-way ANOVA test and Tukey's post hoc test.
The least extruded debris was obtained with the WaveOne Gold instruments compared to the TRUShape and TruNatomy files (p < 0.001).
Debris extrusion occurs independently of the motion or design of the instrument. The WaveOne Gold system outperformed TRUShape and TruNatomy files in this study.
本研究比较了使用TRUShape 3D适形锉、TruNatomy锉和WaveOne Gold往复式系统进行根管预备后挤出碎屑的量。
将51条严重弯曲（25 - 40°）的近中颊根管根据用于预备的旋转系统分为三组，每组数量相等，分别使用TRUShape、TruNatomy或WaveOne Gold锉。将挤出的碎屑收集在预先称重的玻璃小瓶中。使用单因素方差分析和Tukey事后检验对数据进行统计学分析。
与TRUShape和TruNatomy锉相比，WaveOne Gold器械挤出的碎屑最少（p < 0.001）。
碎屑挤出与器械的运动或设计无关。在本研究中，WaveOne Gold系统的表现优于TRUShape和TruNatomy锉。
