[A propos of the premolars and molars in milk and permanent dentition of dogs (author's transl)].

On the base of our investigation the last 2 teeth of each half-jaw were established to be molars in the milk dentition of dogs: on the upper jaw they are distinguished by a third mediopalatal root and masticatory surface, articulating with the corresponding two molars on the lower jaw. In permanent dentition the fourth premolar of the upper jaw is distinguished by a third mediopalatal root, its masticatory surface articulating with the first molar of the lower jaw, peculiarities characterizing it as the first molar of the same jaw.
