256 EXPOSED PULPS.

the ether or chloroform, filling over it. This method
has the advantage of completely filling and occupy-
ing the space, and exactly conforming to the part.
When the exposure is at a large orifice, if the pulp is
healthy, and the constitution of the patient good, the
same general course of -treatment may be adopted,
except that more care and skill will be necessary in
the performance of an operation. Indeed, it is

difficult to make a good operation in cases of this
kind, using for the covering only a soft or flexible
material.
A method of operating, that is probably more effi-
cient than any other, is, to prepare the cavity as
already directed, place on the pulp two or three drops
of collodion or solution of gutta-percha, letting it
partially stiffen, and then over this fit a gold cap as
exactly as possibly, so that it shall rest on the solid
dentine jfar enough from the orifice of exposure to

preclude it from injurious influence on the pulp. On
this, the filling is introduced as usual, care being had
not to displace the cap, which, in all such cases,
should have a seat made for it, formed at the time
of the preparation of the cavity.
When the pulp of a tooth becomes by exposure,
inflamed or diseased, some more special treatment is
indicated, and usually it is therapeutic. In every
such case, the treatment will contemplate either the
