Brachycephalic breeds of dogs, and more recently cats, have been gaining popularity as pets. According to the Cat Fanciers' Association, Persian and Exotic cats have ranked as the most popular purebred cats in the United States in the past few years.1 The structure of their skulls gives these cats a unique appearance but may also result in developmental dental anomalies2,3 that can be categorized on the basis of number, shape, structure, and position. These anomalies can cause problems on their own but can also contribute to oral and dental diseases,4 the most commonly reported diseases in feline veterinary practice.5,6 Thus, information on the prevalence and types of dental anomalies in brachycephalic cats, particularly Persian and Exotic cats, would help veterinarians counseling owners of these cats and individuals considering obtaining them.
To the authors' knowledge, only 1 published report7 has suggested that certain cat breeds are predisposed to dental disease, and studies8–10 evaluating and characterizing dental abnormalities according to breed or skull anatomy are scarce and mainly address dog breeds. The goals of the study reported here were to determine the prevalence of dental anomalies in a population of purebred, brachycephalic Persian and Exotic cats from various geographic regions and analyze potential relationships with oral disease.
Preliminary results were published in Portuguese as part of a dissertation research project of Dr. Louro supervised by Drs. Mestrinho and Requicha. Presented in abstract form at the 25th European Congress of Veterinary Dentistry, Dublin, Ireland, May 2016.
