Objective: To determine the prevalence of periodontal
disease and gindivitis and their relationships with probable
influencine, University of Tehran, Iran.(1992-2000). Design: Case series. Animals: 300 dogs were Used in the Study.
Material and methods: Animals with 6 months of age and older include in this study. Factors like: age, diet,
content of bone in the diet (hardness of diet) and occlusion
conformation were recorded in each animal. Based on oral examinations and factors like: dental calculus, depth of gingival sulcus, dental mobility and loosing teeth, the
gingival status of the dogs were determined as: healthy, gingivitis (primary and irreversible lesions)and
periodontitis (irreversible and advance cases).
Statistical analysis: Chi-square test and the frequencies in percent. Results: The frequency rate of gingivitis and periodontitis
in the study were 24% and 12% respectively. Age and
occlusion conformation had not any significant influence on disease progression. Small breeds had a higher
tendency for the dental problems(gingivitis=32.8% and
perodontitis=24.8%) in comparison with larger breeds(gingivitis= 19.2% and perodontitis=0.9%).
Periodontal disease was more common in older animals in
a manner that none of the animals over 5 years old had
healthy gingiva. Furthermore the dogs that had access to bone in their diets had lesser periodontal problems (jealthy
gingiva=79.9%). dental calculus deposits were more
abundant and gingival sulcus was deeper in maxillary
forth premolars and first molars teeth but mobility and
loosing problems were more common in incisors. Discussion: With respect to results of this study
periodontal disease was common in dogs referred to small
animal hospital, faculty of Veterinary Medicine University of Tehran. Therefore, especial attebtion should be paid to
the oral hygiene situation and dog’s especially small
breeds and older animals should be fed with a diet sufficient of hard material. J.Fac. Vet.Med. Univ. Tehran.
