Title (EN) TOOTHBRUSH AND BRISTLE
(FR) BROSSE A DENTS ET SOIES
Abstract: front page image
(EN)Toothbrush (1) comprising a plurality of T-shaped bristles (5). Each of the bristles (5) comprises an elongated cleansing head (11, 12) terminated at each end by rounded ends (13, 27) and having between the ends a plurality of cleansing elements (12, 24). The rounded ends (13, 27) are provided for presenting a non-abrasive surface to the subgingival surfaces (17) surrounding a tooth when the cleansing surface of the cleansing head (11, 12) is moved across the surface of the tooth during cleansing of the tooth. In one embodiment, the cleansing elements (12, 24) are conically shaped members (12) terminated by a relatively sharp tip. In another embodiment of the invention the cleansing elements (12, 24) comprise parallel, substantially rectangular members (24) terminated by a relatively sharp edge (25). While flexible, the tip or edge (25) of the cleansing elements (12, 24) of the head (11, 22) generally remains in contact with the surface of the tooth while the head (11, 22) is moved across the surface of the tooth.
(FR)Une brosse a dents (1) comprend une pluralite de poils en forme de T (5). Chaque poil (5) comprend une tete allongee de nettoyage (11, 12) terminee a chaque bout par des extremites arrondies (13, 27) et ayant entre les extremites une pluralite d"elements de nettoyage (12, 14). Les extremites arrondies (13, 27) sont concues pour presenter une surface non abrasive aux surfaces sous gingivales (17) entourant une dent lorsque la surface de nettoyage de la tete de nettoyage (11, 12) est deplacee transversalement a la surface de la dent pendant le nettoyage de celle-ci. Dans un mode de realisation, les elements de nettoyage (12, 24) sont des organes de forme conique (12) termines par un bout relativement pointu. Dans un autre mode de realisation, les elements de nettoyage (12, 24) consistent en des organes paralleles, sensiblement rectangulaires (24) termines par un bord relativement pointu (25). Tout en etant flexible, le bout ou bord (25) des elements de nettoyage (12, 24) de la tete (11, 22) reste generalement au contact de la surface de la dent lorsque la tete (11, 22) est deplacee transversalement sur la surface de la dent.
