loo THE TREATMENT OF TEETH
counteracted by the lateral use of the point, as well
as the sides of the wedge, and what may be called a
mechanical cohesion of the surface produced by the
great compressing power of the absolute point.
It is often a great convenience to use short
lengths, or oblong pellets, cut from a rope. One end
of the short length is placed against the floor and
pressed up to a side wall. The protruding end is
then folded over and carried down to the floor, and
laterally packed, leaving the doubled end or loop-like
projection protruding slightly beyond the orifice.
Each pellet or piece is thus folded once on itself.
In filling approximal cavities in incisors and canines
the gold is first packed against the cervical wall, and
more pellets are introduced and pressed in the direc-
tion of the cervical wall, taking care the gold is
worked firmly against the lateral walls until the cut-
ting edge is nearly reached. One or more pellets are
then packed against this wall, until a small space, or
hole, only remains to be filled up between the cutting
edge of the gold and the rest of the filling. Fill up
this space, by directly driving a pellet into it of suffi-
cient size to completely fill it up when well condensed.
Then proceed to make holes in the plug, and fill
them up as already described. The presence of the
adjacent tooth usually renders the labial part of
the plug (in working from the back) difficult to easily
