Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a toothbrush, and more particularly to a toothbrush that is suitable for the prevention and treatment of periodontal ligament diseases and is designed to reach deep into the gingival sulcus.

Even in the natural world, hard objects that are found in places with water are easily infested with various organisms that grow in water, and the gingival crevices in the oral cavity are no exception. In other words, there are places on the tooth that are perfect habitats for microorganisms, that is, ecological niches, including the gingival sulcus. Grows on hard surfaces. Some microorganisms attach themselves to teeth and multiply, invading the gap between the tooth and the gingival margin, and if left untreated, they gradually cover the surface of the tooth root. It is already known that the bacteria that live on the teeth of people with very good periodontal ligaments are very different from the bacteria that live near diseased tissues. Additionally, depending on the disease, the degree of parasitism varies depending on the type, tissue, and behavior of the bacteria. For example, the disease is caused by spirochetes and glidingrods.
, and it has something to do with amoeba and the like. Toxins brought by such microorganisms are a large number for the periodontal ligament,
- When infected, the periodontal ligament becomes inflamed, weakens, and peels off from the surface of the tooth root. Therefore, the main purpose of treatment for periodontal ligament disease is to prevent and eliminate bacteria that spread toxic products in the gingival sulcus and cul-de-sac.
The aim is to suppress the radioactivity (radicular 1nrecLion).

Conventionally, such treatments have been primarily performed at dentists. In particular, new treatment methods involve collecting samples from the root of the tooth every time a patient visits the dentist to check the number of white blood cells and the extent of motile bacteria. Suspicious areas in the oral cavity are then cleaned with a liquid antiseptic.
% solution is used. After cleaning, living bacteria and dead bacteria are carefully removed from the tooth root surface using a scaler 1, a file, or other collecting instruments, and the tooth is scraped many times with the collecting instrument.

While receiving treatment from a dentist as a patient, I habitually brush my teeth and use floss between my teeth every day.
ing), brushing the interproximal surfaces, and cleaning with liquid antiseptics or liquid disinfectants).

However, if the interdental attachment progresses, that is, if the symptoms progress to the point where cavities are formed in the teeth or the bone around the teeth breaks down,
It becomes difficult to suppress the proliferation of bacteria and the increase in white blood cells with only medical treatment or home remedies. When this happens, the patient must undergo treatment for two to three weeks to suppress the bacteria.
For example, you will have to take antibiotics such as tetracycline HCL. In that case, 250mg
Tetracycline 4 times a day, including after meals and at bedtime.
Take with water. If the results of the microscopic examination are negative two weeks after you start taking the drug, you can stop taking the antibiotics, but if the result is not negative, or if your symptoms worsen even after taking the antibiotics, Continue taking antibiotics for another week.

However, if the antibiotics you are taking are not effective, for example, if you have an acute condition such as a mural abscess, the doctor will stop taking the antibiotics, collect bacteria from the tooth root surface, and then treat the patient. Patients are to be informed of home regimens that are deemed appropriate. Antibiotics will not be ordered again unless purulent or latent purulent bacteria are rediscovered by microscopic examination.

, at the initial stage of such therapy, the patient is 6-7°
You will have to take medicine at regular intervals. During treatment, patients whose symptoms have worsened are clinically examined every two to three months, and microscopic bacterial tests are also performed to detect new bacterial activity occurring in and around the tooth roots. It is kept to a minimum. At the same time, each time the patient visits the dentist, cleaning and scaling with antiseptics (
Dental plaque removal) is performed as appropriate.

Whatever oral hygiene procedures a patient must perform should not be neglected, as they are effective in reducing the lifespan of pathogenic bacteria that live on tooth surfaces. This is unacceptable. By using various salts (sodium chloride, sodium carbonate, sodium ricinoleate, sodium periodate, aluminum chlorate, magnesium sulfate, zinc phenolsulfonate, etc.), it is possible to suppress bacterial activity on the tooth root surface and its vicinity. If you can, you should not neglect oral hygiene procedures.

Apart from treatment at the dentist, if there is food residue in the mouth, especially carbohydrates, it is easy for bacteria to proliferate (also, it is easy to attach and grow on the tooth surface, so if possible, brush your teeth immediately after eating. It is important for patients to perform interdental cleanings.In addition, before going to bed and after the last meal or snack of the day, patients are often advised to take the following steps:

1. Perform interdental cleaning using thread or dental tape. When this is done, the gap between some of the adjacent teeth can be widened and removed, but the surface of the collapsed area is still insufficiently cleaned.

2. Rinse with water after cleaning between teeth. For patients with severe dental tissue damage, start with intraoral cleaning without interdental cleaning. If the tissue damage is severe, warm saline is usually used during the initial stages of treatment. If the patient regularly uses an irrigation device, such as a WaLer Pick (trade name), set the fountain intensity setting knob to the low pressure side unless directed otherwise by the physician. We will explain how to use the cleaning nozzles (some of which are made to order) using models next to the chairs, but if necessary, we will demonstrate them at the sink.

3. After the aforementioned cleaning, treatment is taken with a mixed solution of 3% hydrogen peroxide, salt, (sodium chloride), baking soda (sodium bicarbonate). To give an example of how to prepare this mixed solution, first pour a capful of hydrogen peroxide into a tumbler, and then add 1/4 teaspoon of salt. Dip a toothbrush in the mixture to moisten the tip, then dip it in baking soda. The baking soda then adheres to the tip of the toothbrush, much like a conventional toothbrush, which is coated with baking soda to begin with. The toothbrush thus prepared is placed in the oral cavity, allowing the solution to soak into the gingival margins and interdental spaces. At this time, it is normal to not brush the teeth with a toothbrush. 11:4 Instead of brushing the toothbrush, use the sharp barb on the free end of the toothbrush handle (for example, Patra 600
1 Use a rubber prick attached to a toothbrush to connect @root surfaces and @l! on the front and back sides of the teeth. 1 Remove bacteria and pus from the gap by wiping. At this time, if you use an external mirror with a miniature lamp, you can easily and definitely perform this method. After cleaning each tooth in this way, brush the teeth with a brush coated with the above-mentioned mixed solution.

After completing the above steps, brush your teeth using a small toothbrush with soft bristles, but at this time, make sure that the toothbrush is tilted 45 degrees to the gingival sulcus, and move it vigorously back and forth. the groove between the tooth and the gingival margin (i.e.
Rub the antiseptic paste into the gingival sulcus. In this case, the power of using an electric toothbrush is much more advantageous than doing it by hand. In particular, an electric toothbrush that allows you to swing the toothbrush in a circular motion allows you to rub the soda paste into the gingival sulcus and other hard-to-reach areas.

In particular, the electric toothbrush manufactured by Water Pik is suitable for this purpose because it can be oscillated in a circular motion as described above. For example, [Perio Ai]
d, trade name)].

If you use a toothpick with a special handle, you can apply the paste to areas that require more vigorous rubbing. It is also possible to use other special toothbrushes depending on the situation. In any case, you will need to receive guidance from a dentist or dental hygienist until you are able to perform this technique.

After brushing your teeth with the chemical as described above, rinse them with water until all residual salt is removed. However, for patients whose salt intake is restricted, magnesium sulfate (Epsom salt, Mg5O,) may be used in place of sodium chloride and sodium bicarbonate in the above-mentioned drugs. In this case, for first-time users, it may taste bitter, but there is no particular problem. Additionally, with the substitution of magnesium sulfate, PACE-R becomes somewhat rough. Glycerol, glyoxide,
Other activators may also be used. The effects of using this drug and the progress of treatment can be confirmed by periodically observing specimens collected from the tooth root space under a microscope.

4. If the gums have softened and the tooth root surface has become sensitive, use a cotton swab, prickly bristles, brush, etc. to apply a gel-like fluorine compound (neutralized or weakly acidified 1
, ()% fluoride thorium gel, which can be made with a prescription. ) Add 2-3 drops of This fluoride application treatment should be performed after the teeth have been cleaned as described above, and the patient should not gargle after the treatment. Then, the stinging pain will be relieved within 2-3 days. This fluorine coating treatment may be performed again if necessary.

As mentioned above, since steps (1) to (4) have to be performed, it is not only very tedious, but also takes 35 minutes or more if done every day. In addition, as a dentist, it takes manpower to perform such treatment, and if the patient has to perform it himself,
This is difficult to do unless you have a good memory. Therefore, apart from the above-mentioned step (5), there has been a desire for a toothbrush that allows the remaining steps to be completed once or twice.

BACKGROUND OF THE INVENTION To date, several toothbrushes suitable for cleaning the gums and surrounding areas have been proposed. For example:)5Iin・
Jolu+ O, ButlerCo
, ) from the product name [Profsa Brush (Proxal)
The toothbrushes sold at rusl+)J are sized to penetrate into the interproximal spaces between the teeth and are supported by special handles. This toothbrush is disclosed in US Pat. No. 4,222,143.

It is desirable to be able to clean the interproximal spaces between teeth, and the present invention is designed to thoroughly clean the flat areas between the gums and teeth.

A variety of toothbrushes suitable for cleaning teeth and gum areas are commercially available. There are already commercially available toothbrushes that have bristles that are softer and longer than the bristles in the center of the toothbrush, and that can simultaneously massage the gums and clean the teeth. The purpose is to There are some toothbrushes on the market that have curved bristles or have bristles on both sides. Among these toothbrushes, for example, the toothbrush disclosed in U.S. Pat.
-around) In addition to being J-shaped, the handle has an upwardly curved part, so if you hold the handle flat, you can brush the inside of your teeth, and the upwardly curved part will not hit your front teeth. It looks like this.

U.S. Pat. No. 2,697,239 also discloses a toothbrush with a curved head. This toothbrush is designed so that, when in use, the handle protrudes outward from the mouth, particularly in a direction substantially perpendicular to the gum line of the teeth being brushed.

Although there are various types of conventional toothbrushes, the head section with bristles is curved to make it easier to brush the teeth and also to clean flat areas. To date, a toothbrush with bristles on both sides of the head has not been developed. When the head is curved, the direction of movement of the toothbrush when brushing teeth can be determined in one direction, thereby allowing the toothbrush to be aimed only at the area within the oral cavity. For example, when the stem between the head and the handle turns its bristles downward, the toothbrush curves to the left with respect to the handle. Useful for brushing the side areas. However, it is too bulky to use as a toothbrush for brushing the teeth on the lower right and upper left jaws.

Furthermore, if you want to remove the interdental grooves, the head of the toothbrush should be curved so that the bristles can reach between the gums and the roots of the teeth without causing lacerations. is sometimes necessary.

By equipping your toothbrush with bristles suitable for cleaning the grooves of your teeth, you can make the daily dental treatment procedures much easier and faster. Seem. That is, if the bristles can get into the grooves, it is possible to not only dislodge teeth, but also use it as a regular toothbrush without much effort.

OBJECTS OF THE INVENTION In view of the above, the main object of the present invention is to provide a toothbrush suitable for cleaning teeth, particularly grooves in various places on teeth. Furthermore, the toothbrush is controlled and shaped so that the bristles can reach the grooves formed by the gums and thoroughly clean the grooves, especially when treating periodontal ligament diseases. It is another object of the present invention to provide.

The purposeful toothbrush of the present invention simplifies and reduces the time required for daily home therapy for patients, and allows even people of average intelligence to learn the procedure firsthand. It has the advantage of being easy to use.

Structure of the Invention According to one embodiment of the present invention, the head of the toothbrush is curved, and bristles are planted on both sides of the head so as to extend in opposite directions.

The curved head forms an extension of the toothbrush handle, and since both sides lie within a plane of curvature, the bristles can easily reach the flat grooves between the teeth and gums.

According to another aspect of the present invention, good control of the toothbrush is achieved by having at least one row of bristles tilted inward toward the concave surface of the curved head. Not only that, but it also allows the hair to easily reach the grooves. The controllability of the toothbrush can be further improved by providing the handle of the toothbrush with a finger rest for placing the thumb and other fingers.

Furthermore, since the bristles are implanted in the head portion of the toothbrush when the toothbrush reaches adulthood, the bristles can be inserted into the grooves below the gingival margin and into the adjacent interdental areas.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 to 3, 21 is a toothbrush according to the present invention, and this toothbrush 21 consists of a handle 23 having a handle 25 and a head portion 27 for supporting flocking. As with conventional toothbrushes, the handle 25 and head portion 27 are preferably integrated. The head portion 27 is substantially flat and has both surfaces 29, on which brushes 31 are erected and extend in opposite directions. The flat head portion 27 is curved laterally so that both surfaces 29 draw an arc.

FIG. 3 shows how the brushes 31 extend from both surfaces 29 of the head portion 27 in opposite directions.

When viewed from FIG. 1, the head portion 27 of the toothbrush has a handle 25i.
When viewed from above, the toothbrush is curved to the right, but when the toothbrush is turned over, the head portion 27 is curved to the left as shown in FIG.

Therefore, if brushes are placed on both surfaces 29, the front and back surfaces will be symmetrical. In addition, as will be clear from the description below, even if the head portion 27 is curved, it is more convenient for all the teeth to have only one head portion, as will be described later.

The brush 31 is made of soft or extremely soft bristles with rounded tips in order to thoroughly brush flat areas without causing lacerations to the soft tissue of the gums. is desirable. By bending the head portion 27 as described above, the brush 31 can be inserted into grooves. If you want to improve the accessibility to the groove in this way,
- The row or rows of main groups may be tilted as shown in FIGS. 4 and 5. In FIGS. 4 and 5, the brushes 33, 34, 35 are inclined toward the fourth part 37 of the head parts 27', 27'', and although the angle of inclination may be arbitrary, Generally, the angle is 15° from a plane parallel to the curved longitudinal axis of the section.

In particular, in FIG. 4, in order to be able to clean the underside of the gingival sulcus with a particularly gentle application of the toothbrush, there is a section of the head section 27 that is suitable for this purpose. It is desirable to make the brushes densely grown as shown in 39.

Furthermore, if the brush 31 is tilted inward, there is an advantage that the implanted bristles do not rub the inner surface of the cheek roughly.

In the embodiment shown in FIGS. 15 and 16, the brushes are flocked at an angle with respect to the main axis of the head part, and
It extends perpendicularly from both surfaces of the head portion. Especially the first
In FIG. 5, the head portion 27a is connected to the handle 25,
It is twisted so that the angle a between the main axis A-A of the handle 25 and the main axis B-B of the head portion 27a is 42° to 48°, preferably 45°. Then, the surface areas 28a, 28c, 28 of the head portion 27A are flocked with hair.
b.

28d is a slope inclined so that the angle β is approximately 10' to 15°, and slopes 28a and 28c are
1 and slopes 28b and 28d are separated by steps 30'a and 301+, respectively. These slopes 28a
, 28b, 28c, and 28d are inclined with respect to the main axis B-H of the head portion 27a, and the brushes 34a,
Since the brushes 34b, 35a, and 35b extend from the respective surfaces of the head portion 27a in a direction orthogonal thereto, the brushes are inclined with respect to the main axis B--B. Generally, the lengths of the brushes 34a, 35a, 34b, and 35b are exactly the same.

In an alternative embodiment of the head section shown in FIG. 16, the head section 27B is twisted relative to the handle 25 by the same angle as the head section of the embodiment shown in FIG.

However, as is clear from the comparison between FIG. 15 and FIG. No stepped portion is formed on both surfaces of the head portion 27b,
Rather, it is a continuous surface. As shown in FIG. 16, the head portion 271] is approximately wedge-shaped;
The thickness of the portion of the head portion 27b indicated by W is thicker than that of the portion on the opposite side.

The brushes 34 and 35 touch both surfaces 28e and 28f of the head part.
and extends perpendicularly to it. Also, both surfaces 28e
, 28f is approximately 10° to the main axis C-C of the toothbrush.
It is inclined at an angle γ of 15°. In other words, both surfaces 28e and 28f are at an angle of 20° to 30° to each other.
It forms an angle of 0°. Both surfaces 28 of the head portion 27b
Since the brushes 34 and 28f are inclined as described above, the brushes 34 and 35 are perpendicular to the surfaces 28e and 28f, but are planted at an angle with respect to the main axis C-C. It turns out. Also in this embodiment, the brush 34.3
5 are usually the same length. Needless to say, in the embodiments shown in FIGS. 15 and 16, the tip of each flocked hair constituting the brush is also rounded.

Although the brushes in the toothbrushes shown and explained so far are shown as being constructed by forming two rows of flocked hair on each surface of the head, the number of rows is not limited.
Various modifications can be made to the material 14 as well. For example, a brush with rounded tips may be made of nylon as usual, but it is also possible to use natural bristles such as raccoon dog bristles. Furthermore, the length and angle of inclination of the brush can be selected in any manner as long as the purpose of the present invention is achieved.

Hereinafter, how to use the toothbrush 21 according to the present invention will be explained with reference to FIGS. 6 to 8. In order to remove the flat part of the tooth and make it visible, implant hair into the gingival sulcus 3.
It is best to hold the toothbrush so that the brush makes an acute angle to the surface of the tooth so that the tooth can enter the tooth. As shown in Figure 8,
Usually, the gingival sulcus 41 is diseased or the teeth 43 are separated by some distance when treatment is ordered. Therefore, the toothbrush 21 is applied so that most of the grafted hair comes into close contact with the gingival margin 45 at the boundary between the gum and the tooth, and the gingival groove 41 where the gingiva contacts the tooth. In particular, it is desirable that a portion of the bristles 31 enter the gingival sulcus and come into contact with the gingival sulcus 41 and the flat portion of the tooth 43.

In order to allow the toothbrush to be held as described above, the handle portion 25 has a special shape as shown in FIGS. 1 and 2. In FIGS. 1 and 2, the handle 25 is bent so that recesses 49 are formed on both sides of the handle. Therefore, if you put your finger on the rounded part 51 of the handle part 25, your thumb will naturally come into contact with the recess 49, but at that time, you should either put your thumb on the recess 49 or touch the recess 49 and the head. It is up to the user's preference whether to apply it to the part of the handle 23 between the handle 27 and the handle 27. still,
Since there are brushes on both surfaces of the head and there are recesses 49 on both sides of the handle 25, the toothbrush according to the invention is, so to speak, reversible. In other words, it can be used even if the front and back sides are changed. Therefore, in the case shown in FIG. 6, one side A of the toothbrush is oriented upward, but in FIG. 7, it is used with one side A facing downward. In any case, a brush extending from the surface 29 of the head part opposite said side A is in contact with the teeth. However, in FIG. 6, among the two rows of brushes 31, the bristles 31 in the fourth row of the head part contact the outside of the teeth, and in FIG. 7, the bristles 31 in the row on the opposite side mainly contact the teeth. are in contact. As is clear from the drawing, if you try to brush another tooth, you will notice that the tooth has a row of bristle implants 31.
will come into contact. Although not shown, when brushing the outside of the teeth, it is also possible to close the jaw and brush the upper and lower teeth at the same time. This can also be done more successfully if the flocks constituting the brush are tilted as shown in FIG. 5, FIG. 15, or FIG. 16.

In order to brush down to the gums in the interproximal spaces between teeth, it is convenient to use a small toothbrush with a curved head, as shown in FIGS. 9 to 14. First, as shown in FIG. 9, brushes 57 are provided on both surfaces of a curved 5-rad portion 59 of a small-sized toothbrush 55, with bristles 57 implanted in a negative row. This brush 57 may be one in which one bristles are arranged outside at a predetermined interval, or it may be one in which a plurality of bristles are made into a bundle and arranged outside at a predetermined interval as shown in the figure. Furthermore, the bristles are made of the same material as the toothbrush 55,
It may be formed integrally when the toothbrush 55 is molded; in this case, the head portion 5 is used to form the brush 57.
This eliminates the hassle of having to perform hair transplantation.

In other words, it is possible to reduce the number of manufacturing steps for the toothbrush 55. In addition, as shown in FIG. 11 and FIG. Even if the brush were to be oriented in such a way as to result in contact with the head 59, let alone the brush 57, there is the advantage of being able to clean that part of the tooth.

FIGS. 13 and 14 show how to use the small toothbrush constructed as described above. Generally, when periodontal ligament disease has progressed considerably, the gingiva near the affected area recedes downward, so the gap 65 between adjacent teeth 67, 68 widens. Although this adjacent gap 65 may be said to be widening, it appears to be somewhat closed. Therefore, the length of each flocked hair constituting the brush 57 should not exceed 4 mm, taking into consideration the physical dimensions of the head portion 59.

In the illustrated embodiment, the length of the flocked hair is about 2 mm, so the distance from tip to tip of the flocked hair on both surfaces of the head portion 59 is 6 mm. This may seem large, but when brushing the gingival sulcus with the brush 57 on one surface of the head section 59, the brush 57 on the other surface comes into contact with the teeth, causing a force to be applied to the brush 57 on the one surface □. This is sufficient to make it possible to add. Since the small toothbrush 55 is literally small, the amount of external force that the user can apply with his or her hands or fingers is limited. Therefore, the small toothbrush 55 is
Since almost no external force other than push-in, pull-out force is required when brushing, the handle 67 is flat and wide enough to be held between the thumb and index finger. The fact that the handle part 67 is made flat means that it is not gaping, which is convenient for gripping with fingers, as described above, but rather
As shown in the figure, it is convenient to insert the head portion 59 into the gap between adjacent teeth or to tilt it. In addition, the handle portion 67 is symmetrical about the longitudinal axis of the toothbrush 55 so that the toothbrush 55 can be used facing either the front or the back.

Note that various modifications can be made to the present invention. For example, it is also possible to form the toothbrushes described with reference to FIGS. 1 to 8 and the toothbrushes described with reference to FIGS. 9 to 14 at both ends of one handle, respectively. It is.

Although the structure is different from the present invention, the basic concept of providing toothbrushes at both ends of one handle is, for example, described in US Patent No. 890,
No. 143.

Furthermore, in the small toothbrushes described with reference to FIGS. 9 to 14, the head portion 59 can be made linear. In this case, if the head portion 59 is made flexible, The same effect as that of a small toothbrush having a head portion 59 which is curved from the beginning can be expected. In any case, a small toothbrush with a straight head may be well suited for patients who do not need to rotate the toothbrush along a curved surface.

Furthermore, in any of the toothbrushes, the toothbrush holder of the electric toothbrush may be shaped so that it can be inserted into the socket without forming the handle portion 51.67 as shown.

In the illustrated embodiment, the handle portion 5L67 and the head portion are described as being integrated, but they may be separated into one piece from each other. In this case, the teeth are brushed on the outside. Sometimes, if one brush gets wet, you can connect another brush to the common handle and continue brushing your teeth.

In particular, performing dental pine surgery with a dry toothbrush is effective in preventing sepsis.

Therefore, it should be understood that such modifications are included in the present invention as long as they do not depart from the scope of the present invention.
