title: Relationship between diet, dental calculus and periodontal disease in domestic and feral cats in Australia.
abstract: OBJECTIVE
  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.
  
  
  METHODS
  Twenty-nine feral cats and 20 domestic cats were included in the study.
  
  
  METHODS
  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.
  
  
  RESULTS
  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.
  
  
  CONCLUSIONS
  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.
