The early effects of segmental surgery on the human pulp

The teeth of two patients requiring preprosthetic segmental surgery were removed between 4 and 10 weeks postoperatively. The pulps of these teeth were examined histologically using sound teeth from patients of the same age as controls and it was generally found that the teeth from the repositioned segment retained their vitality; there was progressive degeneration of nerves except for the nonmyelinated nerves of the autonomac nervous system, which remained intact.
