Abstract

The displacement amplitude of endosonic files was measured with the aid of light microscopy in order to determine the power output of different ultrasonic units. The results showed that there was a substantial difference in the displacement amplitudes when the same size of file was used in different ultrasonic units made by the same or different manufacturers. File fracture was found to be a problem when files were driven at high displacement amplitudes.

摘要

借助光学显微镜测量了超声锉的位移幅度，以确定不同超声设备的功率输出。结果表明，当在由相同或不同制造商生产的不同超声设备中使用相同尺寸的锉时，位移幅度存在显著差异。当锉在高位移幅度下驱动时，发现锉折断是一个问题。
