262 EXPOSED PULPS.

stroy the vitality of the pulp, and then remove it ; but,
on the contrary, where there is vigor, a capacity
of endurance, it is preferable to remove the pulp
at once by an operation. To accomplish this, there
are two or three methods of manipulation. In
the first place, however, by whatever method it is
removed, it should be fully exposed ; the orifice of
exposure should be as large as the pulp-chamber, and
the entrance as nearly as possible on a line with the
tooth's axis; hence it will be necessary in many
cases to make an opening into the pulp-chamber at a
point different from that of the opening caused by the

decay. For instance, in the incisor teeth, when the
decayed cavity is small, on the side, near the margin
of the gum, penetrating to the pulp-chamber, and
exposing the pulp, the entrance through this opening
into the canal will be almost at right angles with it
and in such case it would be impossible, through this
opening, to manipulate freely in the root; and it
would be necessary to make an opening with a drill
through the palatal portion of the tooth directly into

the canal and on a line with it ; which opening should
be large enough readily to allow of a removal of the
pulp through it, and of an unimpeded performance of
all the subsequent operations on the canal of the root.
After the pulp has been exposed by the proper
opening, the instrument should be selected for its
