166 TILLING TEETH.

Dr. Badger describes a method of filling a small
cavity on the posterior proximal portion of a second
molar, the third molar gone. The cavity is formed
with a bur drill. A cylinder is then formed in the
usual manner, and forced through a series of holes in
a drawplate, down to the size of the bur with which
the cavity is formed. The block is thus rendered

quite dense. The cavity is then dried, and the block
forced into it, which it exactly fits, protruding a little
from the orifice. This block is pierced in the center
with a sharp instrument, and a small dense roll forced
into it ; and all is then condensed and finished in the
usual manner.
Pellets.—Pellets made by rolling fragments or
pieces of foil between the thumb and fingers, are used
by some operators, and with them they profess to
make as good filling as by any other method. They

are made of various sizes, and packed into the cavity
with sharp-pointed or serrate-pointed instruments.
The pieces may thus be very solidly worked to-

gether, and a good filling made, provided the pellets
are not too large ; they should be small enough to
permit the point or points to work through them into
the preceding portions. Some operators use pellets
and crystal gold together. This may do very well,
if the adhesive property of the gold is employed; but
in that case, either form of the material would answer
