The maxillary and mandibular teeth were observed by means of the scanning electron microscope and also their vascular supply was investigated using the so-called infusion material. The obtained results are as follosw ; 1. The so-called monocuspid hinged tooth is situated on the so-called dental pedicle with intervene anular sulcus. Three generations of the teeth have their dental pedicles and there are osseous trabecles among the pedicles. 2. First and second generations of the teeth have the superficial and deep capillary net around each of the teeth, which are connected with oblique capillaries, and surround the dental crown and dental pedicle respectively. 3. The dental pulp has no capillary. 4. The capillary plexus under the enamel organs can be seen and this capillary plexus sends small capillary to the dental primordium developping and moving in direction to the mature teeth. In the third generation of the teeth the superficial capillary net surrounds each of them and in the second or first generations of the teeth the newly developed deep capillary net surrounds each of them.
