Abstract

L'invention concerne un système de distribution d'une résine de scellement pour puits et fissures des dents, libérant du fluorure. Ce système comprend une cartouche ayant une buse avec paroi entourant un passage capillaire débouchant sur une ouverture et partant d'une chambre cylindrique enfermant une composition de résine de scellement à libération lente ayant une viscosité inférieure à 30.000 cps et comprenant un monomère acrylique polymérisable, des particules de verre libérant du fluorure et un sel renfermant du fluorure. Ce sel est au moins 2 fois plus soluble dans l'eau que le fluorure de calcium. La buse a un rapport longueur sur diamètre d'au moins 6 et elle peut facilement être pliée en arc pour former un angle d'au moins 30 degrés entre la ligne centrale de la chambre cylindrique et la ligne centrale de l'extrémité distale de la buse.
