Operator Responsibilities

Use a non verbal signal to indicate a need to exchange an instrument; this avoids tedious and repetitious verbal communication throughout the workday.
Withdrawal of the used instrument from the operative field often serves as a non verbal signal and it repositions the used instrument for better access by the dental assistant.
Place the used instrument in their hand in a position that enables the assistant to safely retrieve it.
The assistant grasps the used instrument.
The assistant transfers the new instrument.
Maintain eyes on the operative field.
Refrain from removing instruments from or replacing instruments onto the pre-set tray.
