Infection ControlQuestion 75 of 100
What should be done with handpieces and other devices attached to dental unit waterlines after each patient?
a.Wipe the outside with alcohol and reuse immediately
b.Flush the device to discharge water and air for about 20 to 30 seconds, then clean and heat sterilize the handpiece
c.Soak the handpiece in a holding solution until the end of the day
d.Rinse the handpiece under running tap water only
Explanation
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.
