f. The Fifth Step. The fifth step (the last step) is the withdrawal. The dental
specialist holds the used instrument in the third and fourth fingers opposed by the
thumb. He then takes the first two fingers and opposes the thumb on the instrument
and releases it from the third and fourth fingers. Now he holds the instrument between
the thumb and the first two fingers. Then, the dental specialist is ready to replace the
used instrument on the preset tray. See figure 4-14. For this action, the tray must be
positioned properly alongside the patient's face and over the dental specialist's lap. In
returning an instrument to the operating tray, lay it down gently and return it to its former
place in the arrangement. If you should drop an instrument, leave it and take a fresh
one from the instrument cabinet.
