The effects of electronic dental anesthesia on the neuropeptides in rat tooth pulp
Abstract：AIM: To examine the influence of electronic dentalanesthesia(EDA) on pulpal neuropeptides in rat. METHODS: Immunohistochemical method. RESULTS: Vitality testing caused the SP-, CGRP-immunoreactive nerve fibers disappeared completely in the pulp but not in the periodontium or the gingiva. While the EDA caused the SP-, CGRP-immunoreactive nerve fibers decreased in the pulp and disappeared completely in the gingiva of the tooth involved. CONCLUSION: The pulp vitality testing excited the afferent nerve fibers in the pulp only, while the EDA excited the afferent nerve fibers not only in the pulp but also in the gingiva. The afferent nerve fibers were excited possibly belong to the different functional groups. Excitation of each group of fibers will cause algesia or analgesia respectively.
