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

Experientia. 1978 Oct 15;34(10):1354-5. doi: 10.1007/BF01981467.

Abstract

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.
