Giải thích
Devices connected to the waterlines are flushed for roughly 20 to 30 seconds after each patient to expel material that may have entered the turbine, and handpieces are then cleaned and heat sterilized between patients. Wiping with alcohol does not sterilize an internal lumen. Soaking in a holding solution or rinsing under tap water neither cleans the internal channels nor sterilizes the device.
