Abstract


The present paper using classical and transmission electron microscopy brings the first data on the pulp of the fangs of Viperidae (poisonous serpents with terrestrial or semi-aquatic habits).

The pulp of the fangs of Viperidae shows a poor collagen and fibroblast content and a high developed vascular system.

The odontoblasts are polarized, with a high organelle content. The interconnections are constituted of lateral «gap junction» systems.

At a late secretion stage, the odontoblastic processes show a poor cytoplasm, mainly constituted of microfilaments.
