  • the brush hair penetrates through at least one of the electrodes, the ions reach the tip of the brush hair that is electrically conductive with moisture, and the ions flow to the teeth and gingiva where the brush hair tip contacts. This causes the calculus to break down or the gingiva to be activated by a known ionic effect.

Abstract

Brosse à dents dont la tête (2) est pourvue de deux sortes de matières (5, 6) dont le potentiel électrique est très différent, par exemple de l'or et de l'aluminium, lesdites matières étant électriquement connectées, au moins partiellement, l'une à l'autre. Des poils (3) sont implantés au niveau de la tête de la brosse au moins dans une de ces matières. Une grande quantité d'eau et/ou de dentifrice présente dans la bouche lorsque la brosse est utilisée agit comme un électrolyte pour former un système de cellules avec les électrodes desdites deux sortes de matières. Le système génère une grande quantité d'ions à chaque électrode, en fonction du mouvement de l'énergie électrique. Grâce aux poils (3) qui passent à travers au moins une des électrodes, les ions atteignent les extrémités des poils (3) contenant de l'eau et électroconducteurs, puis ils se répartissent entre les dents et les gencives en contact avec les extrémités des poils de la brosse, de sorte que le tartre est décomposé et que les gencives sont massées par l'échange ionique.
