264 EXPOSED PULPS.

points presented in passing the instrument up the
canal, to cut or lacerate the pulp. In the removal of
the pulp from the teeth of young persons, care should
be taken lest the instrument pass entirely through
the foramen, at the apex of the root; but with adults,
there is little or no danger of such an accident.
The directions given here would be quite sufficient,
if closely followed, for the removal of the pulps of
the six anterior superior teeth. For the removal of

the pulps from the bicuspids, the entrance can ordi-
narily be effected through the decayed cavity.
Usually, there is some lateral compression of the
roots of these teeth ; and the canal through the root
corresponds in its formation, so that it represents a
mere fissure expanded a little on each side of the
center. It is often difficult, and requires very deli-
cate manipulation, to remove all the pulp from these
fissures : a very fine instrument may be pressed down

each side, and yet a portion of the pulp remain in
the center. This difficulty is most fully presented in
those cases in which there has been an apparent,
though abortive, effort of nature to produce two roots.
The removal of the pulps of the molar teeth is a
more extensive and complicated operation. The pulp
to be operated upon should be fully exposed, the
orifice of exposure being made as nearly as possible
of the size of the pulp-chamber; and the instrument
