摘要: 生命活动中的生物电化学现象已被科学界所公认,生物体存在着特有的生物电位,如表皮电位、神经电位、脑电位、心脏电位、牙体电位等.1969年Heimansohn曾提出假说"电子流从牙体表面流向牙髓",这假说首次由我们的实验数据得到了证实,证明了这一假说的正确性.这些生物电位在生命活动中起着决定性的控制作用.

Abstract: 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 twoparts of tooth has been obtained experimentally,the statistical average being 11.1mV,Anexperimental method of simulating biological potential of living tooth has been establishedfor leaving body tooth.Ion transferred to tooth hard organism was studied by simulating thebiological potential of tooth.Change of biological potential of tooth in the real environmentof 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 bioelectricfield.Scientific basis for the oral local administration has been provided.

Key words: bioelectrochemistry, biological potential, tooth, SrCl2, NaF
