To compare the dental calculus scores and prevalence of periodontal disease in domestic cats eating commercially available canned and dry foods with those in feral cats consuming a diet consisting of small mammals, birds, reptiles and insects.
Twenty-nine feral cats and 20 domestic cats were included in the study.
A dental chart and dental calculus scores were recorded using the maxillary canine, maxillary third and fourth premolar, mandibular canine, mandibular fourth premolar and first molar teeth on both sides. Periodontal disease was recorded using gingival recession, increased periodontal pocket formation, radiographic alveolar bone loss, osteomyelitis, furcation and root exposure, and the presence of calculus as indicators.
Dental calculus scores were significantly higher in domestic cats than in feral cats. There was no statistical difference in the prevalence of periodontal disease between the two groups.
It can be inferred that diet may play a role in the accumulation of calculus, but a diet based on live prey does not protect cats against periodontal disease.
比较食用市售罐装和干粮的家猫与以小型哺乳动物、鸟类、爬行动物和昆虫为食的野猫的牙结石评分和牙周疾病患病率。
本研究纳入了29只野猫和20只家猫。
使用两侧上颌犬齿、上颌第三和第四前磨牙、下颌犬齿、下颌第四前磨牙和第一磨牙记录牙科图表和牙结石评分。使用牙龈退缩、牙周袋形成增加、放射影像学牙槽骨丧失、骨髓炎、根分叉和牙根暴露以及牙结石的存在作为指标记录牙周疾病。
家猫的牙结石评分显著高于野猫。两组之间牙周疾病的患病率没有统计学差异。
可以推断饮食可能在牙结石的积累中起作用，但以活体猎物为基础的饮食并不能保护猫免受牙周疾病的侵害。
