• Equus caballus
• Premolar
• Wolf tooth

In horses, the first premolar teeth of the upper arch, or wolf teeth are small and characteristically vestigial, appear positioned immediately mesial to the root of the first molar tooth, do not act functionally in chewing and can also cause pain in animals. There were evaluated 63 animals of Campolina breed and 58 of Thoroughbred in relation to the presence or absence of wolf teeth. The findings showed that 42.86% of the Campolina horses presented wolf teeth, as well as 3.45% of the Thoroughbred. The variable frequency found discloses that the presence of this tooth is a particular and individual feature of animals. It was observed by applying the Fisher%26apos;s test (p %26lt;= 0.05) that among equine breeds Thoroughbred and Campolina, there was significant difference (p %26lt;= 0.0001). Otherwise for each of the breeds the occurrence of presence of this tooth among the genders was not observed Thoroughbred (p %26lt;= 0.496) and Campolina (p %26lt;= 0.083).
