ELECTRONIC TOOTHBRUSH

摘要

PROBLEM TO BE SOLVED: To extremely improve introduction effects of fluoride ions. SOLUTION: This electronic toothbrush is formed by planting a conductive brush 2 at the tip of a handle 1 and is provided with a power supply part impressing a voltage between the conductive brush 2 and an electrode 10 provided in the handle 1, and is provided with a control part defining a current supplied between the conductive brush and the electrode as a pulse current. The pulse current is supplied to control depolarization in a tooth so as to remove a problem of polarization inhibiting the fluoride ion introduction in the tooth. COPYRIGHT: (C)2006,JPO&NCIPI
