[Comparison of the three-dimensional behaviour of the relief of the enamel crown and dentine crown in the permanent dentition in the mole (author's trnasl)].

1. As an example for the dentition of the insectivores, the teeth from 20 wholly conserved skulls of moles were investigated and measured before and after electrolytic decalcification. Every crown was described and photographically registered in the calcified and decalcified states. 2. The relief of the enamel crown was compared to that of the dentine crown. Almost without exceptions, the form of the dentine crown narrowly corresponded to that of the enamel crown. 3. The 3rd lower premolar can be an exception: in one case, its dentine crown showed two cusps while its enamel crown demonstrated only one of them. 4. The form of the crown is determined by genetically fixed and not by functionally induced growth-factors.
