Abstract

It was hypothesized that CO2 laser irradiation may reduce the early responses to nociceptive stimuli during tooth movement. The distribution of Fos- immunoreactive (Fos-IR) neurons in the medullary dorsal horn of rats was evalu- ated. Two hours after tooth movement, Fos-IR neurons in the ipsilateral part of the medullary dorsal horn increased significantly. CO2 laser irradiation to the gingiva just after tooth movement caused a significant decrease of Fos-IR neurons. PGP 9.5-and CGRP-positive nerve fibers were observed in the PDL of all study groups. It was suggested that CO2 laser irradiation reduced the early responses to nociceptive stimuli during tooth movement and might not have adverse effects on periodontal tissue.
