OBJECTIVE
This study compared the quantity of extruded debris after instrumentation with TRUShape 3D Conforming files, TruNatomy files, and the WaveOne Gold reciprocating system.
MATERIALS AND METHODS
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.
RESULTS
The least extruded debris was obtained with the WaveOne Gold instruments compared to the TRUShape and TruNatomy files (p < 0.001).
CONCLUSIONS
Debris extrusion occurs independently of the motion or design of the instrument. The WaveOne Gold system outperformed TRUShape and TruNatomy files in this study.
目的
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。
材料与方法
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。
结果
与TRUShape和TruNatomy锉相比，WaveOne Gold器械挤出的碎屑最少（p < 0.001）。
结论
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。
