A nine year old neutered male Lab was referred for a fractured right maxillary 4th premolar. The owner complained that the patient was showing a decrease in appetite. The oblique slab fracture extended subgingivally but at the time of referral the presence of a pulp exposure was in question. The patient had previously been treated by another veterinarian for a right in–fraorbital swelling with antibiotics and steroids, resulting in temporary improvement.

A twelve year old neutered male Poodle was referred for evaluation and treatment of a chronic, recurrent fistulous tract on the ventral aspect of the rostral right mandible. This lesion had been present for at least one year. The patient was painful when touched in this area and the owner felt that he had been exhibiting signs of “head shyness” for over a year. Numerous exploratory procedures had been performed to search for a cause of these symptoms and foxtails had been removed on at least two occasions. The patient had been placed under anesthesia for these procedures four times in the past year.

February 2010 (pdf 1.1mb) A fourteen month old neutered male Toy Fox Terrier was referred for
assessment and treatment of a discolored right maxillary canine tooth.

See the previous case report for a complete discussion of the pathogenesis and rationale for treatment. The owner in this instance elected root canal therapy to save the tooth and retain its function.
