Oral and dental anomalies in purebred, brachycephalic Persian and Exotic cats

OBJECTIVE To determine the prevalence of dental anomalies in brachycephalic cats from various geographic regions and analyze potential relationships with oral disease. DESIGN Prospective multicenter cross-sectional study. ANIMALS 50 purebred Persian (n = 42) and Exotic (8) cats. PROCEDURES Cats were anesthetized, and a complete dental examination, dental charting, 3-view oral photography, and full-mouth dental radiography were performed. RESULTS Malocclusions were observed in 36 (72%) cats. Crowding of the teeth was evident in 28 (56%) cats, with the incisors being most commonly affected. Malpositioned teeth were noted in 32 (64%) cats, with abnormal orientation being the most common anomaly followed by rotation and impaction. Numerical abnormalities were present in 38 (76%) cats, including 6 (12%) with hyperdontia and 32 (64%) with hypodontia. Periodontal disease was reported in 44 (88%) cats, and cats with periodontal disease were older than cats without. Tooth resorption was evident in 35 (70%) cats. O...
