Dentition in brachycephalic dogs
|
The aim of the research was to determine the number of teeth, their arrangement in the lower and upper dental arches and the manner of teeth placement in dental alveoli of alveolar processes respective for facial bones in brachycephalic dogs.
Investigations were conducted on 45 adult dogs of various age and both sexes. Morphotype qualification was based on skull index ZyZyAP x100. The pattern of canine permanent dentition that is most common and widely approved as correct was described as 31423143 . The total number of permanent teeth amounts to 42. Only in one (2.22%) out of 45 observed dogs a complete dentition in both dental arches was present, as in the formula above. Full dentition in the lower dental arch was observed only in 6.67% of studied specimen and in the upper dental arch – in 42.22% of dogs. The accepted number of permanent cheek teeth in dogs is 6 in the upper dental arch and 7 in the lower dental arch. The studies performed show that in brachycephalic specimen the reduction of these teeth and rotation related to alveolar processes are common. Own observations suggest that the following 31323132 should be recognized as a correct formula of permanent teeth in this morphotype.
