Reinnervation of teeth after segmental osteotomy.
The reinnervation of 8 canine teeth denervated by segmental osteotomy has been investigated in cats by using electron microscopy. 12 weeks after osteotomy, the mean total number of axons at the canine apices was 36% of that found in normal animals. The myelinated axons were smaller than normal with thinner myelin sheaths. In non-myelinated fibres, there were fewer axons per fibre (Remak bundle) and more fibres containing only one axon. The proportions of myelinated and non-myelinated fibres were normal.
