Abstract

This work is carried out to confirm the existence of the surface potentials in extracted tooth by electrochemical method. The surface potentials were measured between enamel crown’s buccal side and tooth root. Surface potentials examined in all the teeth in the presence of KCl. It is found that potential increased with increasing KCl concentration and after acid corroded. The results suggest that potentials can be affected by the surrounding electrolytes and establish an electrical double layer. It is also found that on passing electric current through enamel causes degradation.
