The purpose of this study was to investigate the effect of electrical anesthesia indoor
by non-acupuncture point stimulation on inhibition of amplitude of digastric EMG
evoked by noxious electrical stimuli in teeth and gingiva. Experiments were performed
with dogs anesthetized with intraperitoneal pentobarbital sodium in an initial dose of
30mg/kg. Maintenance doses of 4.0ml/hour were given through a cannula in the femoral
vein using a constant infusion pump. Anterior belly of digastric muscle was exposed
and a pair of 0.1mm wire electrodes were inserted for E.M.G. recording. Bipolar
electrodes were inserted into the labial and lingual surface of upper canine and the labial
area of upper gingiva. Noxious stimuli we delivered to the tooth and gingiva through
those electrodes by electric stimulator. Non-acupuncture point stimulation of 2Hz was
delivered bilaterally to the femoral area. Amplitudes of digastric E.M.G. were measured
from the oscilloscope and the monitor connected to amplifier at different intensities of
electronic anesthesia of 1 volt, 4 volt and volt. The inhibited rate of the amplitudes of
digastric E.M.G. were analysed statistically with paired t-test. The following results
were obtained :
1. Non-acupuncture point stimulation with intensities of 1 volt, 4 volt and 10 vomit
showed the inhibitory effect on pain of 15%, 25%, and 16% in teeth and 15%, 18% and
12% in gingiva respectively.
2. In tooth, statistical significance was observed between control and each group. In
gingiva, there was statistical significance between control and group 1,2 except group 3.
From these results, low frequency electrical stimulation of non-acupuncture point
resulted in reducing of dental and gingival pain, it could be used as adjunct to other
pain control methods.
