Neuropeptides in the dental pulp: distribution, origins, and correlation.

It is known that many factors participate in the process of inflammation and pain transmission. Recently, various neuropeptides have been demonstrated in the intrapulpal nerve fibers immunobiohistochemically. These neuropeptides may play some role in the process of inflammation and transmission of pain sensation. In this presentation, the distribution, origins, and correlation of neuropeptides in the dental pulp is reviewed.
