Multifocal Odontoblastic Dysplasia in a Dog

摘要

A two-year-old Boerboel dog presented for a discolored left maxillary canine tooth. Dental radiographs revealed abnormally mineralized pulp within the discolored tooth. Similar radiographic findings were also seen in both maxillary third incisor teethand in the remaining canine teeth to varying degrees. The discolored tooth was treated hy surgical extraction and histopathology revealed abnormal dentin deposition within the canal indicative of dentin dysplasia. Although not previously documented in the dog, the pulpal changes in nndtiple teeth of the dog reported here were similar to those described for odontoblastic dysplasia in humans. This case report includes a review of developmental abnormalities of dentin in humans and pulpal response to inflammation and injury.
