214 CLASSIFICATION OF DECAYED CAVITIES.

pits, and make a groove from one to the other. Some
operators prepare these cavities by making pits in
each of the walls. This, however, is unnecessary, if
the cervical wall is properly prepared.
The cavity being prepared, the rolls of bibulous

paper or napkin should be placed on the gum inside,
and between the gum and the lip; and if the former
has been wounded between the teeth, or if it elimi-
nates mucus, a small piece of soft wood or of rubber
should be crowded down upon it below the cavity.
The gold, prepared as already described, should then
be introduced with a small plugger serrated with four
points, and somewhat flattened about a line above the

point, so as to be freely used' when introduced into
the cavity. The gold is taken up on the point of this
plugger, and condensed in the pits of the cervical wall;
which being completely rilled, and the gold extending
from one to the other, the foundation is ready for the
remainder of the rilling.
Great care is requisite in packing the gold into these
cavities, perfectly to adapt and adjust it to all points,
so as to insure its thorough contact with every part
of the interior. If the form of the tooth has been
measurably retained, and the border of the cavity is
even, the surface of the plug should, when finished,
be slightly convex, or as nearly the original form of

the tooth as practicable; and, in introducing the fill-
