[Tooth homology in mammals].
The development of the chewing, lacerative and omnivorous dentition type was confirmed on the base of the author's studies on the dentition of placentalia representatives. The use of vegetable food by the rodents and herbivorous mammals induces an efficient development of molars, absence or reduced number of incisors and canines of the upper jaw and increased number of incisors and absence of canines of the lower jaw, resulting into the proposal of an alteration of the dentition formula for rabbits and for the rest of the rodents (Simplicidentata), for herbivorous and for horses. In beasts of prey, besides the efficient development of the canines, a transition of the premolars and certain molars into laceratives is found. In omnivorous mammals, together with the efficient development of canines, an efficient development of molars and premolars as chewing teeth is also established.
