Abstract

La présente invention se rapporte à une brosse interdentaire (1, 1') ayant une partie brosse (2) qui comprend deux pieds torsadés ensemble (4A, 4B) d'une partie fil (4) et des filaments de brosse (5) maintenus serrés entre les pieds (4A, 4B), et à un procédé permettant de produire une telle brosse interdentaire (1, 1'). Afin d'améliorer en particulier la limite de fatigue en flexion de la partie fil (4), selon l'invention, une partie de fil (4) réalisée en acier austénitique est utilisée, qui présente une teneur en chrome de 15 à 17 % en poids, une teneur en manganèse de 12 à 16 % en poids et une teneur en molybdène de 0 à 4 % en poids et la partie fil (4) est formée ayant une section transversale ovale avec une ovalisation O dans une plage comprise entre 0,4 et 0,9, l'ovalisation O étant mesurée en tant que rapport entre une longueur (LQk)) d'un petit axe transversal (Qk) et une longueur d'un grand axe transversal (Qg) de la section transversale.
