part (near the root canal at the needle handle). If you grip the lower part (blade or moving part), it will wear the metal part of the file folder and the resin part. [Picture Picture 21 Picture 22 b) When measuring the length of root canal, please don’t use the metal needle file. If you operate the device without the dentistry glove,it will cause leakage and the result of measurement will be inaccurate.Therefore, please use the resin needle file and remember don’t touch the metal part with finger.
it is inconvenient to measure the back teeth [Picture 23]. Picture 23 4.2.7 Please remove the lip hook,file clip or touch probe after shutting down. 4.2.8 The components that touch body must be autoclaved under high temperature and high pressure. The shell and measuring wire should be cleaned by 75% alcohol. Attention: Avoid the silk-screen when cleaning.
