摘要： Disclosed is a probe for dental therapy and examination, which comprises an elongate bundle (1) of fibers extending generally parallel to the axis of elongation. The bundle is narrowed at one or both of its ends (2, 2'. 2"), and the fibers are secured to each other so that the fiber bundle (1) is coherent but the fibers define capillary passageways (5) therebetween. The narrowed ends(s) (2) may have a globular enlargement (3) or may be sharp ended (2') or blunt-ended (2"). One end of the bundle may be enlarged to form a handle portion (6).

摘要： A method for manufacturing a non-superelastic file comprising the steps of:
(i) providing a superelastic file having an austenite finish temperature; and
(ii) heating at least a portion of the superelastic file to a temperature from 300 °C to 600 °C for a period of time from 5 minutes to 120 minutes to alter the austenite finish temperature thereby forming the non-superelastic file; wherein the altered austenite finish temperature of the non-superelastic file is from 20°C to 40°C;
further comprising the step of
(iii) cooling the portion of the non-superelastic file and
(iv) heating at least a portion of the cooled non superelastic file to a temperature from 300 °C to 650 °C for a time period from 1 minute to 45 minute to shape-set the portion of the shaft thereby forming a shape-set non-superelastic nonlinear file.摘要翻译： 一种用于制造非超弹性文件的方法，包括以下步骤：（i）提供具有奥氏体终止温度的超弹性文件; 和（ii）将超弹性文件的至少一部分加热至300℃至600℃的温度，持续5分钟至120分钟的时间，以改变奥氏体终点温度，从而形成非超弹性文件; 其中非超弹性锉的改变的奥氏体终止温度为20℃至40℃; 还包括以下步骤：（iii）冷却非超弹性文件的部分，和（iv）将冷却的非超弹性文件的至少一部分加热至300℃至650℃的温度1分钟 至45分钟，以形成轴的部分，从而形成形状非超弹性非线性文件。
