An autoradiographic study of the sensory innervation of teeth. II. Dental pulp and periodontium.
Autoradiography of axoplasmically transported proteins revealed that both dental pulp and periodontium receive sensory innervation from the trigeminal ganglion in the form of plexuses and free and organized sensory receptors, including apparent corpuscular ones. Corpuscular receptors in the pulp suggest this tissue may be responsive to modalities other than pain.
