Squamous cell carcinoma in a cat mandible

by Brett on Dec.15, 2009, under Veterinary Dental Cases

This middle aged cat presented with drooling and a rostral oral mass.  Further evaluation revealed severe mandibular inflammation with “floating teeth” present.  Radiographs reveal destruction of bone surrounding the teeth of the left mandible.  The mass crosses the midline in the caudal oral cavity partially displacing the tongue.  Surgical cure is not possible.  Analgesic management has been instituted to provide a good quality of life until discomfort or anatomical problems warrant euthanasia.

Periodontal Disease in a Young Cat Canine Tooth

by Brett on Dec.13, 2009, under Veterinary Dental Cases

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.

This is the same patient from the prior post.  This is an example of Type I tooth resorption on the mesial root and Type II resorption on the distal root.

Tooth resorption in the 3rd mandibular premolar in a cat

This 3rd mandibular premolar has very subtle swelling of the gingiva distal to the crown

Tooth resorption in the 3rd mandibular premolar in a cat

Radiographically you can see the periodontal ligament space on the mesial root classifying this as type I tooth resorption. This requires full root extraction. In the distal root the space is not present and bone is replacing the rooth. In this case crown reduction of more specifically here partial tooth extraction may be performed to remove tooth to the point where only bone is present. This requires extensive experience and a very high powered head surgical magnifyer to perform properly.

Tooth Resorption in the Canine Tooth of a Cat

by Brett on Nov.25, 2009, under Veterinary Dental Cases

This 10 year old domestic short haired cat was referred for oral evaluation and likely tooth resorption and missing teeth this week.  The procedure for crown amputation show here applies to only Type II resorption.  As you can see there is no discernable periodontal ligament space around the root that is in the final stages of replacement with bone.  5-0 monocryl was used to close.  As always regional nerve blocks are employed.

Maxillary Canine Extraction Site Trauma Secondary to the Mandibular Canine Treated by Crown Reduction, Vital Pulpotomy and Pulp Therapy

by Brett on Oct.23, 2009, under Veterinary Dental Cases

This cat had a maxillary canine tooth extracted.  Upon recheck at the referring veterinary hospital the mandibular canine was causing a mucosal defect at the extraction site.  Options for therapy were crown reduction and vital pulpotomy followed by vital pulp therapy or extraction. 
The crown was reduced to the level of the incisors.  Several millimeters of pulp and dentin were removed with a small diamond bur.  Bleeding was minimal and controlled with a paper point.  Mineral trioxide aggregate was placed over the pulp followed by glass ionomer and composite as shown on radiographs.  The purple is the acid etchant applied prior to the composite.  The patient will be checked radiographically in a year to ensure success of the procedure.  The ulcer will heal within 10 days.
