Supernumerary maxillary fourth premolar teeth in five related Burmese cats

This article reports a case series of five Burmese cats with supernumerary teeth. All included cases displayed either unilateral or bilateral supernumerary maxillary fourth premolar teeth. Two cases also displayed supernumerary mandibular fourth premolar teeth, and in one case bilateral supernumerary maxillary third incisor teeth were found. Examination of the pedigrees of the affected cats revealed that all five cats were related with one common ancestor. All patients in this case series were successfully treated.

Supernumerary maxillary fourth premolar teeth in cats have not been reported previously in the literature. As all five cats in this case series were shown to be related, supernumerary maxillary fourth premolar teeth may be yet another heritable health condition affecting the Burmese breed. Therefore, Burmese breeders should endeavour to reduce the incidence of supernumerary teeth within the breed by having animals examined by a veterinary dentist prior to breeding, and neutering affected, as well as related, individuals. Burmese cat owners must be made aware of the condition in order to institute early evaluation, diagnosis and treatment.
