Method of tooth anesthetizing during dental treatment and device for effecting same

摘要

Stablized d.c. voltage signals are applied to a tooth in the course of treatment, preferably, through the electric circuit between the ear lobe and the tooth. The voltage is selected between 1.7 and 2.2 volts. Electroanesthesia is induced by electric signals arriving from a d.c. voltage source which generates voltage of 1.7 to 2.2 volts. The positive terminal of the source is connected to the stomatological instrument, whereas the negative terminal is connected to an ear lobe.
