Definitions
- the present invention relates to improvements in toothbrushes.
- known toothbrushes have a head mounted at the end of a handle, this head having a flat or curved profile comprising, on one of its faces, a series of tufts of bristles.
- the head of known brushes generally has a length of 20 to 30 millimeters, a width of 10 to 12 millimeters and a thickness of 4 to 5 millimeters.
- the free end of the head is often rounded, so as to prevent irritation of the soft tissues of the oral cavity.
- the bristles are grouped in tufts inserted into cavities formed in the head.
- the bristles are often made of nylon and have a variable diameter of up to 0.28 millimeters.
- the present invention relates to a toothbrush arranged so as to allow its use under conditions such that it allows not only the removal of the bacterial plaque which covers the surface of the teeth, but also a massage in the gum. non-keratinized sulcular and junctional epithelium.
- Periodontopathies such as gingivitis
- the present invention relates to a toothbrush allowing the removal of bacterial plaque from the entire surface (non-chewing and chewing) of the teeth, including the surface at the level of the sulcular gum and the interdental surface, as well as a brushing and massage of the sulcus gum ensuring keratinization thereof.
- the subject of the invention is also a toothbrush which differs from conventional toothbrushes, as much by the dimensions and the shape of the tufts of bristles as by the shape and the dimensions of the head carrying these tufts of bristles, as well as by the shapes and dimensions of the handle to which the head is connected. These differences make it possible to obtain a toothbrush offering the advantages mentioned in the previous paragraph, thanks to a method of use radically different from that of conventional toothbrushes, as will be seen below.
- the toothbrush according to the invention which has a head furnished with at least one tuft of individual bristles tangent to one another is essentially characterized in that the tufts or tufts have a width corresponding substantially to the depth of the groove sulcular. In practice, this width is approximately 0.5 to 3 millimeters.
- the head relative to which protrudes at least one tuft of bristles has a constant section of circular or elliptical shape, the diameter of which is approximately 3 to 5 mm, the head length preferably being greater than that of the rows of premolar and molar teeth.
- the head of the brush is connected to a handle of polygonal cross section, while, preferably, the median longitudinal plane of the tuft or tufts of bristles makes an angle of less than 90 ° with the plane of at least one face of the handle of polygonal section, facing the free end tuft or tufts of hair, said angle preferably being 45 °.
- the median longitudinal plane of the tuft or tufts of bristles is a bisector plane with respect to the planes of two symmetrical faces of the handle of polygonal cross section, turned towards the end free from tuft or tufts of hair.
- the teeth are brushed using the free ends of the bristles in an alternating movement.
- the brush according to the present invention is eminently suitable for use according to an original technique allowing the ends of the bristles to penetrate to the bottom of the sulcus groove, between the gingival crest and the teeth, so as to ensure a gentle massage of the internal surface of the gingival gum and to favor the homogeneous appearance of a protective keratinization of this surface.
- the tangent bristles of the brush according to the invention are used. lises to scrape by their lateral surface, rather than to brush by their ends, the lateral surface of the teeth.
- the brush according to the invention shown in Figures 1 to 3 of the drawings, comprises a handle 1 ending in a head 2 carrying a multitude of bristles 3 perpendicular to a face 4 of the head 2 and tangent to each other .
- the handle 1 of the brush can be tilted or curved so that the head 2 carrying the bristles 3 either at a level lower than that of the handle or part thereof, when the brush is placed on a surface with its bristles pointing upwards.
- This arrangement promotes access of the bristles to the teeth, in particular on the lingual side of the dental crown.
- the tuft of bristles 3 may comprise, for example, one thousand two hundred rigid monofilament bristles or strands, for example nylon, with a diameter of 0.22 millimeters, forming a dense tuft, the width La of which corresponds substantially to the depth of the sulcular sulcus, this depth being approximately 0.5 to 3 millimeters.
- the bristles preferably have an identical length and protrude relative to the face 4 of the head 2 over a distance at least equal to the maximum average height of the teeth, ie in practice a length L of 10 to 15 millimeters.
- the free ends of the bristles form a flat surface, this surface however being able to be slightly convex and concave.
- the surface formed by the free ends of the hairs is dense and free of protruding hairs and roughness.
- the length L o of the tuft of bristles 3 is not critical. It can vary, for example, between 15 and 25 millimeters.
- the tuft of bristles 3 is inserted into a window 5 provided with reinforcing bars 7 and pierced in the head 2 of the face 4 thereof on its opposite face 6.
- This face 6 reveals the end of the bristles welded together and having hundreds of capillary conduits.
- the free ends of the individual hairs preferably have the shape of a rounded head, such as a mushroom head.
- the head 2 of the brush advantageously has a width A of approximately 3 millimeters and a thickness of approximately 2 to 3 millimeters, the length L "of this head possibly being from 30 to 60 millimeters.
- the second embodiment of the toothbrush according to the invention differs from that shown in Figures 1 to 3 in that the head 2 has a circular cross section over its entire length and is connected in 8 to a handle 1 having a polygonal cross section.
- the diameter of the head 2 is preferably about 3 to 5 millimeters.
- the head 2 can have an elliptical cross section.
- the handle 1 has a square cross section.
- the median longitudinal plane, shown diagrammatically by the dashed line P1 in FIG. 5, of the tuft of hairs 3 makes an angle less than 90 °, preferably an angle of 45 °, with the plane P 2 of at least one face of the handle facing the free end of the tuft of bristles 3.
- the plane P 1 is a bisecting plane making an angle a of 45 ° with the planes P 2 , P 3 of two symmetrical faces 9 and 10 of its handle 1 of square cross section, facing the free end of the tuft of bristles 3.
- the plane P 1 contains, moreover, the opposite edges 11 and 12 of the handle 1.
- the user has a safe means of properly orienting the tuft of bristles 3 when he takes the brush in hand.
- the user is right-handed and wants to brush the lower teeth, he places his thumb with his right hand on side 10, while when he is left-handed, he applies his thumb with his left hand to side 9 of the handle.
- the handle 1 is held in the right hand in this way, the tuft of bristles 3 is oriented, so as to allow the use of the brush according to the technique described below which is entirely different from the conventional mode or modes use of known toothbrushes.
- the head 2 and the tuft of bristles 3 of the compact sulcular brush according to the invention have dimensions much smaller than those of conventional brushes.
- the brush according to the invention in particular that illustrated in FIGS. 4 and 5, can be used according to a technique making it possible to dislodge the plate. bacterial as well as the desquamated cells of the junctional and sulcular gum, while allowing scraping of the vestibular and lingual surfaces of the teeth.
- the brush is arranged so that its bristles 3 extend parallel to the buccal or lingual surface of the dental crown, that is to say so that the bristles, at their free end, are tangent to the lateral surface of the teeth 13 at their collar 14. Thanks to the reduced width (0.5 to 3 millimeter of the tuft of hairs 3, the free ends 15 of the hairs penetrate into the sulcular groove 16 between the gingival crest 17 and the teeth 13. While the free ends 15 of the bristles are in contact with the bottom of the sulcus sulcus, the lateral surface of the bristles is applied to the lateral vestibular or lingual surface of the dental crown, by marrying, as shown in FIG. 7, the sinuous shape of this crown.
- the head 2 of the brush is then subjected to a low amplitude vibrating back-and-forth movement in the direction of arrows Y, so that the free ends 15 of the hairs 3 pressed into the gingival groove 16 provide a massage and scraping of the interior of this gingival groove 16, while the hairs 3 sweep through their lateral surface the lateral vestibular or lingual surface of the dental crown.
- FIG. 9 shows the sinuous movement which the bristles 3 take in scraping by their lateral surface the coronal surface of the teeth, while the free ends 15 of the bristles massage the gingival groove 16.
- the bristles 3 of the brush according to the invention extend parallel to this lateral surface.
- the free ends 15 of the bristles 3 pressed into the gingival groove 16 undergo almost no displacement in this groove and simply massage the gingival and papillary sulcus. Thanks to this massage and the capillary effect created by the hairs tangent to each other, there is an aspiration of the bacterial plaque from inside the gingival groove 16 towards the dorsal face of the head 2 of the brush, while the surface of the crown and the collar of the teeth 13 is cleaned by the lateral face of the bristles which sweeps across this surface.
- the technique of use described above of the brush according to the invention allows a perfect elimination of the bacterial plaque contained in the gingival groove and a cleaning of the coronal surface and the collar of the teeth, without gingival irritation, without - risk of scratching - or abrasion of the coronal surface and the neck of the teeth and without pressure being exerted by the keratinized part of the gum on the tooth (which avoids any risk of gingival recession).
- Massage of the internal surface of the gingival groove by the free ends 15 of the bristles 3 promotes homogeneous keratinization ensuring protection of the cell layer of this internal surface.
- the shape and dimensions of the head 2 of the compact sulcular brush according to the invention make it practically impossible any brushing liable to cause gingival lesions and other lesions in the mouth of the user.
- the toothbrush may comprise two tufts spaced from one another or more in the direction of the length of the head 2.
- the handle 1 of the brush may have a section in the shape of any regular polygon, for example in the shape of an equilateral triangle, regular pentagon, regular hexagon, etc.
