History
On examination a broken lower right canine was found on this 8year old
Border collie. The broken section of the tooth was investigated, using a
dental probe. An exposure was found and the dog reacted when the probe
was pushed into the exposure. A root canal therapy was suggested to the
owner of the dog as this exposed pulp can easily develop into an abscess
if not root canal treated and sealed off. The necessary appointment was
arranged for the tooth to be restored under general anaesthetic.
Treatment
The dog was given general anaesthetic. The fractured tooth was examined
again and the exposure of the pulp was confirmed. The pulp did not bleed
which was an indication that the tooth was non-vital and has been for
quite a period of time. There was a great possibility that this
situation could develop into an abscess and therefore a root canal
treatment was preformed on the tooth.
The length of the canal was determined with a lateral scull X-ray. The
reaming length was 32 mm and the crown down method was used to ream the
canal. The canal was obturated and sealed with Endorez root canal cement
and GP points. The tooth was also reinforced by constructing an
anatomical fibre post, which was bonded into the tooth with dual cure
resin cement (Nexus 2 from Kerr). The tooth was then restored to normal
form, slightly shorter than the opposite, lower left canine. The whole
procedure was successfully completed, and in approximately one and a
half hours the fractured canine was restored to its normal form and
function. The dog recovered normally and seemed quite content when we
left the operating theatre. An amoxicillin injection was given to
prevent any unwanted bacterial infections after the root canal
treatment.
