Electrical properties of teeth regarding the electric vitality testing

Abstract

In this paper we concentrate on electrical properties of tooth during electrical stimulation using various electrode- tooth interfaces. Established resistances of teeth connections are compared for each type of electrode. Total impedance as well as the voltage step response of tooth is recorded with different electrodes. The current stabilized pulp-tester is built and used to measure the required parameters of stimuli in order to obtain stable and comparable readings. For that purpose intensity-duration curve is recorded. Use of current and voltage stimuli by pulp-testers is reviewed. © 2010 International Federation for Medical and Biological Engineering.
