The instrument should be selected based on the size and location
of the root to be removed. Start with a blade which is approximately
one third the size of the circumference of the root to be removed.
Instruments used for luxation of roots need to be properly held
whilst in use. The handle is placed flat in the palm of the hand
with the forefinger aligned along the long axis of the instrument.
A finger of the same hand or, possibly, a finger of the other hand
must then create a fulcrum and a "rest" or "stop".
The function of the rest is to prevent slippage of the blade.
Holding the wrist next to the body and keeping it straight prevents
excessive force. You cannot overdo the force in this position.
