摘要：

We have reported that pain could be effectively relieved by Nd:YAG laser irradiation in dental or periodontal treatment, and that painting Chinese ink on the mucogingival surface reinforces the efficacy of anesthesia with laser irradiation. However, the effect of Chinese ink on nerve action potentials (a.p.) in this pain relief is not clear. In this study Xenopus tactile nerve fibers were used to clarify this efficacy. Dorsal surface skin was removed with fine tactile nerve bundles, and was put on the filter paper absorbed physiological buffer solution, and fastened on the rubber mat. From a bundle, a.p. with tactile stimuli on the skin surface were recorded by a silver electrode, and counted by the spike counter. After noncontact Nd:YAG laser irradiation (15 pps, 100 mJ, 60 s), with or without Chinese ink painting, tactile responses were periodically recorded. Results were as follows: (1) The conduction of a.p. was reversibly suppressed in the bundle; (2) Chinese ink painting has a considerable effect on reversible suppression; and (3) the suppressive effect was not certain in nerve bundles without Chinese ink painting. These results endorse that Chinese ink painting is effective for patients on dental or periodontal pain control using laser irradiation. (C) 2003 Elsevier Science B.V All rights reserved.
