Innervation of pulp and dentine
pulp
- dense innervation
- extensive branching of axons
- myelinated A? and A? axons
- C - fibres, include sympathetic vasomotor
-
dentine
- nerve terminals extend up to 100 µm into some tubules
- mainly over pulp horns
- < 0.2 µm diam.
- no myelin sheath or Schwann cells
- some probably terminals of myelinated axons
- ? functional contacts with odontoblasts
