A delivery tip (14) for use on a delivery device for applying a dental composition to tooth surfaces includes a tubular member (30) having a proximal end (32) and a distal end (34). The proximal end (32) of the tubular member (30) is coupled to the delivery device, while a plurality of fibrous bristles (50) are disposed at the distal end (34) of the tubular member (30). The fibrous bristles (50) are attached to the distal end (34) of the delivery tip (14) in such a manner that the composition can be delivered through a passageway in the tubular member (30) without interference from the bristles (50). The fibrous bristles (50) can be used in an agitating action to remove entrapped air bubbles from the applied composition, and can also be used to coat the composition on tooth surfaces.
La pointe (14) utilisée sur un dispositif d'application d'une composition dentaire sur les surfaces des dents comprend un élément tubulaire (30) ayant une extrémité proximale (32) et une extrémité distale (34). L'extrémité proximale (32) de l'élément tubulaire (30) est couplée au dispositif d'apport, tandis qu'une pluralité de soies fibreuses (50) est disposée au niveau de l'extrémité distale (34) de l'élément tubulaire (30). Les soies fibreuses (50) sont fixées à l'extrémité distale (34) de la point d'apport (14) de manière que ladite composition dentaire puisse être amenée au travers d'un passage ménagé dans l'élément tubulaire (30) sans que les soies (50) ne génent le passage. Il est possible d'impartir un mouvement d'agitation aux soies fibreuses (50) afin d'éliminer les bulles d'air emprisonnées de la composition dentaire appliquée. Ces soies peuvent être utilisées pour revêtir avec la composition dentaire les surfaces des dents.
