Definitions

  • This invention relates to toothbrushing, particularly in the prevention and treatment of periodontal disease. More specifically, this invention is directed to improving access to the gingival sulcus.
  • the teeth provide a natural habitat, or ecological niche, for microbiological life that is uniquely adapted for growth upon hard surfaces in the fluid environment of the mouth and gingival crevices.
  • Certain types of microorganisms can attach themselves .to the teeth, proliferate and invade the crevice between the gum margins and teeth, and over a period of years progressively coat the root surfaces.
  • the bacteria that populate the teeth of persons with excellent periodontal health differ markedly from those that inhabit the surfaces adjacent to diseased tissues.
  • Associated with disease are populations that differ with respect to the types of cells, their organization, and also their behaviour.
  • Treatment has traditionally been primarily centered in the dental office.
  • a specimen is removed from selected root surfaces and examined for the prevalance of white blood cells and motile bacteria. All probable spaces are then irrigated or treated with an anti-septic solution, e.g., a 1% solution of chloramine-T.
  • an anti-septic solution e.g., a 1% solution of chloramine-T.
  • the root surfaces are carefully debrided with scalers, files, and other instruments to remove living and mineralized bacterial deposits.
  • the scaling instruments are repeatedly passed through an antiseptic during the debridement procedures.
  • Such self-treatment usually comprises, in addition to toothbrushing, dental flossing, brushing inter-proximally and irrigation with various antiseptic or anti-bacterial solutions.
  • the antibiotic may be continued for another week, unless there is an acute problem, e.g., parietal abscess, the antibiotic is not prescribed before the roots have been scaled as described, and the patient has learned a home-care regimen appropriate for his needs. The antibiotic is not used again unless microscopic findings indicate that a pyogenic or potentially pyongenic population has re-established itself.
  • the oral hygiene programs used by patients are not inflexible, as a number of variations can effectively reduce the germ life that forms on the surfaces of the teeth.
  • various salts sodium chloride, sodium bicarbonate, sodium recinoleate, sodium periodate, aluminum chlorate, magnesium sulface, zinc phenolsulfonate, etc.
  • the brush is held at about a 45°angle towards the gingival margins and it is rapidly jiggled back and forth to distribute the antibacterial paste into the crevices between the teeth and gum margins (gingival crevices).
  • an electro-mechanical toothbrush can be very helpful.
  • One that has a fast circular motion will help to spin the soda paste into gingival crevices and other difficult-to-reach sites.
  • the electric toothbrush made by Water Pik works well for this purpose because of its circular motion.
  • a toothpick held in a special handle, "Perio-Aid" may be used in areas where more positive action is needed.
  • Various types of special brushes may be recommended for special situations. Patients need guidance from a dentist or a hygienist for proper use of these procedures.
  • Various arrangements have been advanced which provide brushes which are particularly suitable for cleaning certain areas of the teeth and gums.
  • One toothbrush arrangement surrounds a group of centre bristles with bristles which are softer and longer in order to provide an improved massage of the gums and improve the cleaning of the teeth.
  • a few toothbrushes have been advanced having curved toothbrush heads or toothbrush heds with oppositely disposed bristles.
  • a toothbrush proposed by Gracey in U.S. Patent 1,513,104 provides a wrap-around arrangement for bristles resulting in the majority of the bristles extending from opposite sides of an oval head. By providing an upwardly-curved portion of the stem, the insides of the teeth can be brushes with the handle held flat and the upwardly-turned portion remaining clear of the front teeth.
  • a curved head toothbrush is described in Funk, U.S. Patent 2,697,239.
  • the brushhead is arranged transversely to the stem of the toothbrush, so that the handle extends outwardly from the mouth, perpendicularly to the gum lines of those teeth being brushed.
  • the present invention consists in a toothbrush comprising a longitudinal stem having a rear handle portion and a forward bristle-supporting portion, characterised in that the bristle-supporting portion has two oppositely-facing surfaces from which the bristles extend in opposite directions, and is curved along its length to provide improved access to the gingival areas of the teeth for penetration into the sulcular areas to provide the user with a means to apply the curved portion of the toothbrush to opposite sides of the teeth located in all areas of the mouth, the teeth defining a curved dental profile; the bristles being grouped in tufts and the tufts being arranged in a plurality of rows along the longitudinal length of the bristle-supporting portion with at least some of the tufts being canted with respect to each of the surfaces of said bristle-supporting portion towards the inside of the curve thereof.
  • the invention also consists in a toothbrush comprising a stem defining a handle portion and a bristle-supporting portion, said bristle-supporting portion extending generally in a plane, characterised by said bristle-supporting portion curving along its length in said plane to conform to a curved dental profile and having generally oppositely facing bristle-supporting surfaces, said bristles extending substantially perpendicularly from each of said oppositely facing surfaces which are each inclined with respect to said plane so that said bristles are canted inwardly toward the inside of said curve.
  • the invention further consists in a toothbrush wherein a plurality of tufts of bristles extend from opposite sides of a bristle-supporting portion, characterised by a longitudinal stem having a handle portion forming a rear part of the stem and said bristle-supporting portion defining a forward part of the stem and having two oppositely facing surfaces from which said bristles extend, said portion curving along its length with said oppositely-facing surfaces generally parallel to the curvature of said portion providing improved access to the gingival areas of the teeth for penetration into the sulcular areas, and the bristles extending from two opposite sides of the bristle-supporting portion to permit said improved access by providing the user with a means to apply the curved portion of the toothbrush to opposite sides of the teeth located in all areas of the mouth, the teeth defining a curved dental profile, whilst said handle portion is twisted with respect to said bristle-supporting portion, each of the surfaces of the bristle-supporting portion having slightly inclined portions with a step therebetween, the bristles
  • the invention still further consists in a toothbrush wherein a plurality of tufts of bristles extend from opposite sides of a bristle-supporting portion, characterised by a longitudinal stem having a handle portion forming a rear part of the stem and said bristle-supporting portion defining a forward part of the stem and having two oppositely facing surfaces from which said bristles extend, said portion curving along its length to provide improved access to the gingival areas of the teeth for penetration into the sulcular areas, and the bristles extending from two opposite sides of the bristle-supporting portion to permit said improved access by providing the user with a means to apply the curved portion of the toothbrush to opposite sides of the teeth located in all areas of the mouth, the teeth defining a curved dental profile, whilst said handle portion is twisted with respect to said bristle-supporting portion, the oppositely-disposed faces of said bristle-supporting portion forming an angle with each other so that said bristle-supporting portion is wedge shaped, the tufts of br
  • the bristles are moulded into a bristle-supporting portion of the brush so that the brush may be inserted in the interproximal areas of the teeth for the insertion into the sulcus below the interproximal gum lines.
  • the toothbrush 21 comprises a generally planar stem 23 consisting of a handle 25 and a bristle-supporting head 27.
  • the handle 25 and the head 27 are preferably moulded as a single piece.
  • two oppositely disposed faces 29 which are generally parallel to the plane of head 27 appear on the head 27 from which tufts of bristle 31 extend.
  • the head 27 is generally curvate so that the faces 29 form disc portions.
  • the tufts 31 extend completely from the head 27 so as to occur on opposite sides of the head 27.
  • the view of the toothbrush from Figure 1 shows toothbrush curving (looking from the handle 25) to the right, the same toothbrush can be turned over so as to appear curving to the left as shown in Figure 2.
  • tufts 31 extending opposite the faces 29 of the toothbrush, a symmetry is achieved. It is clear, as will be described later, that, even though the toothbrush is curved, the single head of the toothbrush is useful for all teeth as will be described later.
  • the tufts 31 are preferably made from soft or extra soft rounded tip bristles in order to facilitate thorough cleaning of the sulcular areas without lacerating the soft tissue of the sulcus.
  • the curved contour of the toothbrush head 27 improves access to the sulcus. Further enhancement of the function may be had by angling one or more rows of tufts as seen in Figures 4 and 5.
  • tufts 33, 34 and 35 are canted toward the concave side 37 of toothbrush head 27' and 27". While this cant can be provided at various angles, a cant which is 15° from parallel to the axis of curvature would be typical.
  • a tuft concentration is provided at the point where it is most desired to achieve a brushing action; that is under the sulcus, particularly when a minimum of force is applied by the user.
  • the tufts are canted with reference to the major axis of the toothbrush head and extend perpendicularly from the surface of the head.
  • toothbrush head 27A is twisted with reference to handle 25 so that angle ⁇ between major axis A-A of handle 25 and major axis B-B of toothbrush head 27A is about 42° to 48°, preferably 45°.
  • the surfaces 28A, 28C and 28B, 28D of the toothbrush head 27A from which the tufts extend are slanted at an angle of and are separated by step 30A and 30B, respectively. ranges from about 10° to 15°.
  • tufts 34A, 34B, 35A and 35B extend perpendicularly from the surfaces, the tufts are canted with reference to axis B-B.
  • tufts 34A, 35A, 34B and 35B have the same length.
  • toothbrush head 27B is twisted with reference to handle 25 at the same angle as shown in Figure 5A.
  • the cross-sectional view of the head has the form of a wedge and the surfaces in which the tufts are embedded are not provided with any steps, i.e. the surfaces are continuous.
  • toothbrush head 27B is wedge-shaped, with side W of the head being thicker than the other, T.
  • Tufts 34, 35 extend perpendicularly from surfaces 28E and 28F of the head.
  • Surfaces 28E and 28F are inclined with respect to major axis C-C of the toothbrush head at an angle of from about 10° to 15°.
  • surfaces 28E and 28F form an angle of from about 20° to 30° with each other.
  • tufts 34, 35 are canted with reference to axis C-C although they extend perpendicularly out of surfaces 28E and 28F.
  • tufts 34, 35 have the same length.
  • the embodiments shown in Figures 5A and 5B have rounded corners to prevent the user from lacerating his gums.
  • the toothbrush 21 normally is used in a manner specifically directed to improve access to the sulcular areas. This is accomplished by holding the brush at an acute angle to the surface of the teeth so as to direct the bristles 31 down into the sulcular areas. As can be seen in Figure 8, since the sulcus 41 is normally diseased when such treatment is prescribed, it tends to be separated from its adjacent tooth 43. There, the toothbrush 21 is so positioned that most of the bristles 31 contacting the teeth are closely adjacent the gingival margins 45 defined by the boundaries between the gums and the teeth and consequently the sulcus 41 where the gums contact the teeth. Specifically, it is desirable that at least a portion of the tufts 31 penetrate so as to contact the sulcus 41 and the sulcular areas of the tooth 43.
  • the handle 25 is preferably contoured as can best be seen in Figures 1 and 2.
  • the handle 25 has been twisted, leaving depressions 49 on either side of the handle.
  • the user is then able to grip the round part 51 of the handle 25 with his fingers and is able to place his thumb in one of the depressions 49 or at that portion of the stem 23 leaving adjacent the brush head 27 in accordance with his preference.
  • the depressions 49 occur on both sides of the toothbrush 21, the toothbrush is reversible. Therefore, in Figure 6, side A is turned upward whereas in Figures 11, side A is turned downward.
  • the small brush 55 is provided with a row of bristle tufts 57 which extends from two sides of a curved brushing head 59 in a manner previously described. These tufts can be single-bristle tufts or the multi-bristle tufts 57 shown. Additionally, the bristles can be moulded from the same material together with the remainder of the toothbrush 55, eliminating a necessity to join the bristles in the tufts 57 to the brush head 59 during the moulding of the small toothbrush 55.
  • the interproximal areas 65 between adjacent teeth 67,68 become enlarged during advanced periodontal disease because the diseased gums recede downward. Nevertheless, the interproximal spaces, such as interproximal space 65 remains somewhat confined. Therefore, the small brush 55 according to the present invention should be less than 1 centimeter between the ends of the tufts 57. Therefore, each tuft should be no more than 4 millimeters long in order to accommodate the physical denominations of the brush head 59. In the preferred embodiment, the tufts 57 are approximately two millimeters long, with the total distance between the tips of the tufts being six millimeters.
  • a small flat handle 67 is provided, the handle being suitable for grip between the user's thumb and forefinger. This enables the user to aim and angle the small toothbrush 55 into each of the sulcular areas adjacent each tooth, as can be seen in Figure 14.
  • the handle 67 exhibits a symmetry permitting reversal of the direction of curvature of the toothbrush by the user in a manner such as the handle 25 permits a reversal of the direction of curvature of toothbrush 21.
  • a straight head rather than a curved head may be provided.
  • This type of straight head would readily conform to the curvature of the interradicular sulci. It may well be that such a straight brush head may be advantageous because the patient would not be required to rotate the brush head in accordance with the direction of curvature.
  • the brushes according to this invention would be provided with a stem adapted to mount on conventional motorized (electric) toothbrush handles. This would permit the patient to take advantage of the efficiency of a motorized toothbrush.
  • the brush heads 27, 59 may themselves be made removable from their respective handles 25, 67. This permits the heads to be changed between brushings, giving the heads a chance to more thoroughly dry and therefore reducing sepsis.
