Plain-English summary
A group of dogs with a rare type of jaw tumor called conventional ameloblastoma was studied to understand its symptoms and treatment outcomes. These tumors typically appear as a lump or swelling in the jaw and can cause changes in the bone structure. In the cases examined, the tumors were usually slow-growing and did not spread aggressively to surrounding tissues. Remarkably, none of the dogs experienced a recurrence of the tumor after surgery, even when the surgical margins were narrow.

Abstract
A noninductive tumor of odontogenic epithelium occurs within the tooth bearing regions of the jaw in dogs and fits the conventional definition of ameloblastoma, which is distinct from, and less common than, canine acanthomatous ameloblastoma. In order to clarify the clinical and radiological features of this uncommon odontogenic tumor in dogs, we performed a retrospective study of 20 dogs that were diagnosed between 2007 and 2015. Follow-up information was obtained for 17 of 20 dogs. The study group of dogs showed no apparent age, breed, or gender predilection. Conventional ameloblastoma is typically slow growing, well demarcated, and locally destructive. Tumors most commonly occurred as a mass or focal bony swelling within the maxilla (13/20) or mandible (7/20). Based on cases with available diagnostic imaging, as either dental radiographs or computed tomographic images, the tumors were usually intraosseous and caused mixed lytic/proliferative bone changes. Nevertheless, conventional ameloblastomas did not aggressively infiltrate adjacent tissues and recurrence was not observed within the study group, even in patients with narrow surgical margins or treatment by cyst enucleation.
