PULP DEVITALIZATION AND REMOVAL 215
To Check Hemorrhage, should that ensue, wash the chamber and
canals with cold water, dry as quickly as possible, flood cavity with
a drop of adrenalin chloride and apply a plug of dental rubber,
pressing this into the cavity and holding it for a few minutes. Re-
move the rubber and wash again with cold water. If hemorrhage
continues repeat holding the adrenalin confined longer than before
and applying a little more force. Care should be used in this pro-
cedure as a sore tooth will result when the method has been used
too vigorously. Again thoroughly bathe the canals with cold water
or alcohol and dry.
Discoloration Results from allowing any blood to remain in con-
tact with the dentine, even though it be only from one treatment to
another as the iron of the hemoglobin is absorbed or forced into the
tubuli resulting in permanent discoloration. The use of hydrogen
dioxide is not good practice until the blood has been washed from
the dentinal walls as it oxidizes the iron of the hemoglobin and dis-
coloration will result.
Post-Extirpation Pains may be prevented by pumping into the q
canals phenol with a smooth broach continuing this until the nerve "
stump at the foramen is bathed with this agent. This also has th^
effect of coagulating the mouths of the dental tubuli, resulting ^n (/>
sealing them to agents which may cause discoloration. r , ^^
It Is the Best Practice to Dress the Canal or Canals for a few )
days with a stimulating anodyne which is at least mildly antiseptic,
^^
as the anesthetizing of the pulp has probably so much affected the
tissues in the apical space that there is nothing to guide us in prop-
erly filling the pulp canals.
Immediate Canal Filling in these cases is sometimes practiced
where lack of time demands a hurried completion of the case and
is quite successfully accomplished where all is just right. But so
many times ideal conditions for canal filling are not obtainable that
its universal practice is condemned. However, if there is to be im-
mediate canal filling the pulp canals should be bathed with water
and dried with warm air, flooded with phenol and again dried, this
time with the aid of absolute alcohol, when the canal filling may be
introduced as outlined in the chapter on "The Filling of Pulp
'
Canals.
Devitalization With Arsenic Trioxide is the method in most fre-
quent use and although not always to be preferred to anesthetiza-
tion, it may be used in almost any case with satisfactory results.
Arsenic Should Be Combined With Some Agent to allay the pain
