イオン導入法 (Iontophoresis) についてその研究の歴史

抄録

  Iontophoresis is a kind of electrosterilization.

  Electrolyte molecules are dissolved in water, dissociated and broken up into positive ions (cations) and negative ions (anions). When an electric current passes through a electrolyte solution, cations are attracted to the negative pole (cathode), while anions are attracted to the positive pole (anode).

  This phenomenon is referred to as electrophoresis.

  The resultant ions are destructive to microorganisms.

  The principle of iontophoresis for the treatment of infected root canal is based on this phenomenon.

  Iontophoresis has a long history of nearly one hundred years.

  In this article the history of development of apparatus and the studies on iontophoresis in Japan are described.
