Producing of a T-type voltage application device applying uniform current for bacterial suspensions.

Abstract

The major current treatment of the apical periodontitis had been cleaning of the root canal with chemicals and specialized equipment. Recently, electro-magnetic apical treatment called EMAT have been proposed. However, optimal conditions and sterilization mechanisms in treatment have not been clarified sufficiently. In this study, a device(Trench-type) was produced to apply a uniform current to the target bacterial suspensions for fundamental experiments. The simulation results confirmed that a device had a uniform current density. In addition, it was observed significant electro-sterilization effects in the experimental results. In the future, it is necessary to carry out comparative experiments between heat sterilization and electro-sterilization under precise temperature control.
