Innervation of Dentine

Abstract

Dentine is a specialised mineralised tissue which often becomes exposed by disease or restorative procedure. Once exposed dentine can be very sensitive. Although the present of nerves in dentine is implicated as one of the hypotheses to this clinical feature, its present and extent into dentine is still controversial. This is a review on the present knowledge of the nerve terminal (intratubular axon) in dentine.
