Biological potential of tooth surface and dental pulp has been measured and stud-ied by electrochemical method. For the first time potential difference between these two parts of tooth has been obtained experimentally,the statistical average being 11.1mV. An experimental method of simulating biological potential of living tooth has been established for leaving body tooth. Ion transferred to tooth hard organism was studied by simulating the biological potential of tooth. Change of biological potential of tooth in the real environment of oral cavity has been discussed. Also the feasibility of two commonly used compounds of SrCl₂ and NaF for dental disease was discussed from the viewpoint of the effect of bioelectric field. Scientific basis for the oral local administration has been provided.
