extraction, but the application of endodontictreatments from humans and brachydont species has resulted in endodontictreatments of equine incisors becoming an alternative treatment option, preserving the teeth. 6 Traditional orthograde endodontic
Surgical endodontictreatment entails an apicoectomy, which is the resection of the most apical portion of the root of a tooth, débridement of the diseased periapical tissues, and retrograde filling of the apical pulp cavity. This procedure was
Objective—To evaluate results of root canal treatment
Sample Population—127 tooth roots in 64 dogs.
Procedure—Radiographs obtained before surgery,
immediately after surgery, and during follow-up
examinations after surgery were evaluated by 2 individuals.
Treatment was considered successful if the
periodontal ligament space was normal and possible
preoperative root resorption, if present, had ceased.
Treatment was considered to show no evidence of
failure if possible preoperative root resorption had
ceased but a preexisting periapical lesion had
remained the same or only decreased in size and not
complete resolved. Treatment was considered to
have failed if a periapical lesion or root resorption
developed subsequent to endodontic treatment, if a
preexisting periapical lesion had increased in size, or
if possible preoperative root resorption appeared to
continue after endodontic treatment.
Results—Follow-up time ranged from 1 to 60 months
(mean, 13 months). Treatment was classified as successful
for 87 (69%) roots, as showing no evidence of
failure for 33 (26%) roots, and as having failed for 7
(6%) roots. The success rate was lower for canine
teeth than for maxillary fourth premolar teeth. Roots
with a preexisting periapical lucency or preexisting
root resorption had lower success rates. The use of
intracanal medication and the method and quality of
obturation were not associated with outcome.
Conclusions and Clinical Relevance—Results suggest
that root canal treatment offers a viable option
for salvage of periodontally sound but endodontically
diseased teeth in dogs. (J Am Vet Med Assoc

Treatment and Outcome
The horse was sedated, and endodontictreatment of the affected tooth was performed. In addition, odontoplasty was performed on the occlusal surface of the fractured tooth to temporarily take it out of occlusion and reduce the

Treatment and Outcome
Orthograde endodontictreatment of the left mandibular canine tooth was performed, and the left mandibular
