Definitions
- the present invention relates to a toothbrush comprising a handle of substantially rectangular section and a head furnished with a tuft of bristles substantially tangent to one another.
- Toothbrushes of the type defined above are known from documents US-A-3,754,295 and EP-A-60,592.
- Periodontopathies such as gingivitis
- the present invention relates to a brush defined above arranged so as to allow not only the removal of the bacterial plaque which covers the surface of the teeth, but also a massage at the level of the non-keratinized sulcular gum and the epithelium of junction.
- the toothbrush according to the present invention allows 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 intermediate surface, as well as a brushing and massage of the sulcus gum ensuring keratinization of the latter.
- the toothbrush according to the invention 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 shape and the dimensions of the handle to which the head is connected, these differences making it possible to obtain a toothbrush offering the advantages mentioned in the previous paragraph, thanks to a mode of use radically different from that of conventional toothbrushes, as will be seen more far.
- the toothbrush of the type defined in the first paragraph of this specification is essentially characterized in that its head has a circular or elliptical cross section, the diameter or width of which is less than the width of the handle, in that the bristles the tuft have a length, relative to the head, of about 10 to 15 mm and in that the width of the tuft of bristles is about 0.5 to 3 mm.
- the width of the single tuft of hair corresponds substantially to the depth of the sulcus groove.
- the hairs of the tuft are inserted into an elongated window passing right through the head from one face of the latter to its opposite face, this latter face revealing the end of the hairs welded together and having capillary conduits between them.
- the characteristic shapes and dimensions of the toothbrush according to the invention can be used in a completely different way from that of conventional brushes.
- 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. Furthermore, the tangent bristles of the brush according to the invention are used for scraping by their lateral surface, rather than brushing by their ends, the lateral surface of the teeth.
- the brush according to the invention comprises a handle 1 ending in a head 2 carrying a single tuft comprising a multitude of bristles 3 projecting with respect to a face 4 of the head 2 and tangents l to one another.
- the handle 1 of the brush can be inclined or curved so that the head 2 carrying the bristles 3 is at a level lower than that the handle or part of it, when the brush is placed on a surface with its bristles pointing upwards.
- This arrangement favors the access of the hairs to the teeth, especially on the lingual side of the dental crown.
- the tuft of bristles 3 may comprise, for example, one thousand two hundred rigid monofilamentary hairs or strands, for example made of nylon, with a diameter of 0.22 millimeters, forming a dense tuft, the width La of which corresponds substantially to the depth of the sulcus sulcus, this depth being about 0.5 to 3 millimeters.
- the bristles preferably have an identical length and protrude relative to the head 2 over a distance at least equal to the maximum average height of the teeth, ie in practice a length L o 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 pierced right through in the head 2 of the face 4 of the latter to 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 has a circular cross section over its entire length and is connected at 8 to a handle 1 having a rectangular 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 P 1 in FIG. 2, of the tuft of hairs 3 makes an angle of 45 °, with the plane P 2 of at least one face of the handle turned towards the end free from the tuft of hairs 3.
- the plane P 1 is a bisector plane making an angle a of 45 ° with the planes P ⁇ , 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 i also contains the opposite edges 11 and 12 of the handle 1.
- the user has a secure means of properly orienting the tuft of bristles 3 when it takes the brush in hand.
- the user when the user is right-handed and wants to brush the lower teeth, he places the thumb of his right hand on face 10, while when he is left-handed, he applies the thumb of his left hand to the 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. 1 and 2, 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.
- FIGS. 3 to 5 The technique of using the brush according to the invention is illustrated in FIGS. 3 to 5.
- the brush is arranged so that its bristles 3 extend parallel to the vestibular 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 millimeters) of the tuft of hairs 3, the free ends 15 of the hairs penetrate into the groove sulcular 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 sulcular sulcus, the lateral surface of the bristles is applied to the vestibular or lingual lateral surface of the dental crown, marrying, as shown in Figure 3, the sinuous shape of this crown.
- the head 2 of the brush is then subjected to a low amplitude vibratory back-and-forth movement in the direction of the arrows Y, so that the free ends 15 of the bristles 3 pressed into the gingival groove 16 provide massage and a scraping from the inside of this gingival groove 16, while the bristles 3 sweep through their lateral surface the lateral vestibular or lingual surface of the dental crown.
- FIG. 5 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 tangent hairs one at a tre, there is an aspiration of the bacterial plaque from the inside of the gingival groove 16 towards the dorsal face 6 of the head 2 of the brush, while the surface of the crown and the collar of the teeth 13 is cleaned by the face lateral hair that sweeps across this surface.
- the above-described use technique of the brush according to the invention allows perfect elimination of the bacterial plaque contained in the gingival groove and a cleaning of the coronal surface and the neck of the teeth, without gum 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.
