This patient had what appears to be a normal right mandibular canine tooth.  The left mandibular canine was fractured with pulp exposure. The radiograph shows root resorption and a large pulp cavity with a periapical lucency.  Periapical changes are also present on the right mandibular canine tooth.  The final root canal procedure, the crown prep and crown placement are demonstrated.

The right mandibular canine (top) has a smaller pulp cavity than the left. Periapical lucencies are present on both. The left canine is undergoing apical root resorption as well. The left tooth had exposed necrotic pulp.

Although the right canine is fine on gross examination the pulp on this tooth is also necrotic.

Root canal therapy is the treament of choice.

The tooth is prepared with a chamfer margin and a detailed impression made and sent to the lab from crown fabrication.

A cast metal alloy crown is placed at the next visit to complete the procedure.

This is a 4 year old cat with extrusion, 3 mm pockets.  Radiographic changes show increased PDL space apical to the marginal bone, consistent with periodontal disease.  Other teeth show no changes.  Likely this cat traumatized the tooth predisposing it to periodontal changes.
