Degeneration of unmyelinated axons in the dental root canal induced by 6-OH-dopamine

  • K. Fried

The pulpal nerve fibres of feline incisors were examined ultrastructurally after i.v. administration of 6-OH-dopamine. The presence of degenerating unmyelinated fibres at this site provides conclusive morphological evidence that sympathetic fibres enter the dental pulp.
