[Primary distal anomalies due to Schwann cell separation of human pulp myelinated axons].

This paper reports the presence in the human dental pulp of myelinated axons rich in disordered neurofilaments and with stasis of the axonal flow. These axons underwent a process of separation of their axoplasm by cytoplasmic extensions of the Schwann cells observed for the first time. As soon as the bipartition was achieved, one of the cytoplasmic compartments was lysed whereas the other remained intact.
