This study reviews rim excision as a treatment for canine acanthomatous ameloblastomas (CAA) in dogs with <3 mm of bone involvement. Removal of a canine tooth was involved in 47% of the cases; 33% cases involved the caudal dentition. Follow-up ranged from 3 months to 5 years. No evidence of recurrence was seen. Client satisfaction with cosmesis and the animal's ability to masticate was judged to be good. With appropriate case selection, rim excision appears to be a viable option for CAA and results in improved dental occlusion, cosmesis, and no evidence of epulis recurrence.
