Abstract

L'invention concerne un appareil de mesure de dimension de canal radiculaire. L'appareil de mesure de dimension de canal radiculaire selon la présente invention comprend : un manchon qui est utilisé pour mesurer la dimension d'un canal radiculaire lorsque le canal radiculaire d'une dent est traité, et a une forme de bâton à introduire dans le canal radiculaire ; et un matériau de noyau métallique formé dans le manchon dans la direction longitudinale. Selon la présente invention, l'appareil de mesure de dimension de canal radiculaire est utilisé dans un état dans lequel le matériau de noyau métallique est formé dans le manchon constitué de silicium élastiquement déformable, de telle sorte que le diamètre d'une extrémité du canal radiculaire et la longueur du canal radiculaire peuvent être mesurés en même temps, et la rigidité suffisante peut être garantie par le matériau de noyau même lorsque l'appareil de mesure de dimension de canal radiculaire est formé pour être relativement mince. De plus, lorsque la dimension d'une matière d'obturation est sélectionnée, le diamètre d'une extrémité de la matière d'obturation est mesurée au préalable, de telle sorte qu'il est inutile d'identifier la dimension en déposant directement la matière d'obturation dans le canal radiculaire. Ainsi, la présente invention peut empêcher le gaspillage de matériaux et la fatigue d'un opérateur.
