Abstract

Objectives: The aim of the present study was to evaluate the cutting efficiency of two new reciprocating instruments, Twisted File Adaptive and WaveOne Primary.

Material and methods: 10 new Twisted File Adaptive (TF Adaptive) (SybronEndo, Glendora, CA, USA) and 10 new WaveOne Primary files (Dentsply Maillefer, Ballaigues, Switzerland) were activated using a torque-controlled motor, respectively TFA motor (SybronEndo, Glendora, CA, USA) and Silver motor (VDW, Munich, Germany). The device used for the cutting test consisted on a mainframe to which a mobile plastic support for the hand-piece is connected and a stainless-steel block containing a Plexiglas block against which the cutting efficiency of the instruments was tested. The length of the block cut in 1 minute was measured in a computerized program with a precision of 0.1 mm. Mean and standard deviations of each group were calculated and data were statistically analyzed with one-way ANOVA and Bonferroni t test (P < 0.05).

Results: TF Adaptive displayed significantly greater maximum penetration depth than WaveOne Primary (P < 0.05). In fact, TF Adaptive instruments (Group 1) cut the Plexiglas block to a mean depth of 8.7 (SD 0.5) mm, while WaveOne Primary instruments cut the Plexiglas block to a mean depth of 6.4 (SD 0.3) mm.

Conclusions: Twisted File Adaptive instruments demonstrated statistically higher cutting efficiency than WaveOne instruments.

不同运动的仪器的切割效率：一项比较研究。

研究目的材料和方法：使用扭矩控制电机（分别为TFA电机（SybronEndo，Glendora，CA，USA）和Silver电机（VDW，Munich，Germany））启动10个新型Twisted File Adaptive（TF Adaptive）（SybronEndo，Glendora，CA，USA）和10个新型WaveOne Primary锉（Dentsply Maillefer，Ballaigues，Switzerland）。用于切割测试的设备由一个主机和一个不锈钢块组成，不锈钢块上有一个有机玻璃块，用于测试仪器的切割效率。在电脑程序中测量 1 分钟内切割的块的长度，精度为 0.1 毫米。计算各组的平均值和标准偏差，并采用单因素方差分析和 Bonferroni t 检验对数据进行统计分析（P < 0.05）：结果：TF Adaptive 的最大穿透深度明显大于 WaveOne Primary（P < 0.05）。事实上，TF Adaptive 仪器（第 1 组）切割有机玻璃块的平均深度为 8.7 毫米（SD 0.5），而 WaveOne Primary 仪器切割有机玻璃块的平均深度为 6.4 毫米（SD 0.3）：结论：据统计，Twisted File Adaptive器械的切割效率高于WaveOne器械。
