Abstract

L'invention concerne une composition de traitement dentaire qui contient un agent granulé d'effacement, les granules qui constituent l'agent d'effacement étant dimensionnés pour rouler sur une surface. Les particules ont un diamètre maximum moyen compris entre 30 et 1000 microns et comprennent un précipité de carbonate de calcium. Etant donné que les granules sont sphériques, quand ils sont appliqués sur une surface dentaire, ils roulent sur la surface, absorbant les débris, taches, plaque, tartre ou similaires déposés sur la surface sans endommager la surface dentaire. L'invention concerne également un procédé de traitement des dents qui utilise une composition de traitement dentaire selon l'invention.
