Description

Toothbrush

The present invention relates to a toothbrush, and more particularly, to a toothbrush for periodontal disease.

Generally, a toothbrush is an oral hygiene appliance used with toothpaste, including a handle, a toothbrush head extending from the handle, and bristles provided on the toothbrush head. The toothbrush can be divided into a manual toothbrush and a powered toothbrush.

The manual toothbrush is a simple form having a knob on one side of the toothbrush body. When the toothbrush body is put into the mouth, the bristles are put into the mouth and the bristles are brought into contact with the teeth, and then the bristles are moved while moving the knobs and bristles.

The electric toothbrush includes a toothbrush body, a brush installed at the tip of the toothbrush body, a brush head protruding outward from a side wall of the brush, a charging battery placed inside the toothbrush body, a motor driven by the power of the charging battery, And a dynamometer for rotating the bristles.

Manual toothbrushes are manufactured in various shapes to suit the application, and toothbrushes for periodontal patients are available.

Referring to FIG. 1, a conventional periodontal disease toothbrush is formed with a circular flap 11 in two rows in a toothbrush head 10, and bristles are vertically fixed to the flap 11.

Such toothbrushes for periodontal disease have insufficient elasticity to effectively remove plaque between the gums and teeth because the number of bristles is less than that of a general toothbrush, and accordingly, the bristles are easily worn and are not suitable for use for three months or more.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a toothbrush that can improve the elasticity and cleaning power of bristles provided in two rows.

According to an aspect of the present invention, there is provided a toothbrush comprising: a toothbrush head having a rectangular flap according to a plurality of rows; And a bristle fixed to the floss groove.

The flocking grooves may have a width of 1.0 mm to 1.5 mm and a length of 2.0 mm to 3.5 mm.

The bristles may be inclined by 3 to 10 degrees with respect to a line segment perpendicular to the upper surface of the toothbrush head.

The plurality of rows include a first row and a second row, and the first bristles fixed to the first row and the second bristles fixed to the second row may abut on ends of the bristles.

The bristles may be fine.

And a handle coupled to the toothbrush head.

Therefore, according to the toothbrush of the embodiment of the present invention, the bristles are fixed to the rectangular flute formed by two rows and having a predetermined area, whereby the elasticity of the bristles can be improved.

Further, the bristles positioned along the two rows abut each other at the upper end of the toothbrush head, thereby further improving the resilience of the bristles and further exerting a cleaning force between the gums and the teeth.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the drawings, the same reference numerals are used to designate the same or similar components throughout the drawings. In addition, the preferred embodiments of the present invention will be described below, but it is needless to say that the technical idea of the present invention is not limited thereto and can be variously modified by those skilled in the art.

2 to 4, a toothbrush 100 in accordance with an embodiment of the present invention includes a toothbrush head 110, bristles 120 and a handle 130, And the bristles 120 are fixed to the knife groove, so that the elasticity of the bristles 120 can be improved. The toothbrush 100 is mainly used by periodontal patients.

The toothbrush head 110 may be made of a synthetic resin material that is harmless to the human body and is inserted into the user's mouth when the user brushes the teeth. The toothbrush head 110 may have a plurality of floss grooves 111 and 112 formed on one surface thereof, and the other surface may be formed as a flat surface. The toothbrush head 110 may be formed in a smooth curved shape without corner portions so as not to damage the user's mouth and to resist irritation when the user brushes the teeth.

Referring to FIG. 3, the toothbrush head 110 may be formed with flock grooves 111 and 112 according to two rows. Here, the two columns include a first column (reference left column in FIG. 3) and a second column (reference right column in FIG. 3). That is, the grooves 111 and 112 may be formed along the first row and the second row. The grooves 111 and 112 may have a rectangular shape.

For example, the flocked grooves 111 and 112 may have a width of 1.0 mm to 1.5 mm and a length of 2.0 mm to 3.5 mm. In this case, when the area of the bristle grooves 111 and 112 along the width and length is 1.0 mm x 2.0 mm or less, the area of the bristle grooves 111 and 112 is narrowed so that even when the bristles 120 are fixed, There is no effect of improving elasticity. In addition, when the width of the flossing grooves 111, 112 is 1.5 mm or more, the entire end surface area of the bristles 120 becomes large, making it difficult to penetrate between the tooth and the gum. In addition, when the vertical length of the grooves 111, 112 is 3.5 mm or more, it is difficult to fix the bristles 120 using the flat lines.

Therefore, the flocked grooves 111 and 112 preferably have a width of 1.0 mm to 1.5 mm and a length of 2.0 mm to 3.5 mm.

Referring to FIG. 4, since the bristles 120 are used for periodontal disease, the bristles 120 may be thin and smooth. The bristles 120 are fixed to the bristle grooves 111 and 112 of the toothbrush head 110 such that the bristles 120 have an angle of inclination inclined by 3 to 10 degrees with respect to the line segments perpendicular to the upper surface of the toothbrush head 110 . As a result, the bristles 120 are improved in elasticity and at the same time, plaque between the gums and teeth (hereinafter, gingival sulcus) can be efficiently removed.

The bristles 120 may include a first bristles 121 fixed to the bristle grooves 111 formed along the first row and a second bristles 121 fixed to the bristle grooves 112 formed along the second rows. And may include bristles 122. The first bristles 121 and the second bristles 122 may have their respective ends abutted against each other. As a result, the bristles 120 are improved in elasticity and at the same time, the dental plaque can be efficiently removed.

The handle 130 is provided for grasping the user when brushing teeth, and can be connected to the toothbrush head 110.

Accordingly, since the toothbrush 100 according to the embodiment of the present invention is fixed in such a manner that the bristles 120 are inclined at a predetermined angle in a rectangular flute formed on the top surface of the toothbrush head 110, the brushing force is high when brushing the toothbrush, Even if it is used for brushing for a long time, it can not be bent easily.

Referring to Table 1 and Table 2 below, it is possible to confirm the elastic loss degree and the elastic loss degree index table of the conventional bristles fixed vertically to the circular grooved groove and the bristles fixed at 5 degree inclination to the square grooved grooves having various areas .

Unit: mm Flap heads with a diameter of 1.6 + vertical bristles area
1.2x1.2 flute groove + 5 degree tapered bristles Bristles with an area of 1.5x2.0 + 5 degree inclined bristles 1.5x2.5 grooved grooves + 5 degree tapered bristles 1.5x3.5 flute groove + 5 degree tapered bristles 1.5x4.0 flute groove + 5 degree inclined bristles Elastic loss 24.4% 20.1% 9.8% 7.2% 5.8% 4.2%

division Elastic loss evaluation 1 rating below 10 Most suitable 2 ratings 10-20 fitness 3 ranks 20-30 incongruity 4 ratings 30-40 incongruity

The elasticity loss shown in Tables 1 and 2 is an index indicating the durability of the bristles. The degree of elasticity indicates the extent to which the bristles are worn after the brushing of the bristles. Here, the greater the elastic loss, the greater the widening of the bristles.

The elasticity loss was measured by immersing the toothbrush in the toothpaste slurry and brushing the toothbrush approximately 5,000 times with a brushing machine before measuring the degree of toothbrushing. This elastic loss degree is determined by the following equation (1).

&Quot; (1) "

Elasticity loss (%) = (B-A) / A x 100

In Equation (1), B represents the width of the bristles after brushing of the toothbrush, and A represents the width of the bristles of the toothbrush before brushing.

In Table 1, a conventional toothbrush having bristles fixed vertically to a flute diameter of 1.6 mm in diameter had a resilience loss of 24.4% and was equipped with a 5-degree inclined bristle fixed to a flute groove having an area of 1.2 mm x 1.2 mm The elasticity loss of the toothbrush was 20.1%, and the toothbrush having bristles fixed at an inclination of 5 degrees to the tooth groove of the area of 1.5 mm x 2.0 mm had a resilience loss of 9.8%. The toothbrush having an area of 1.5 mm x 2.5 mm had 5 The toothbrush with bristles fixed at an angle has a resilience loss of 7.2% and a toothbrush with bristles fixed at an inclination of 5 degrees to a tooth groove of 1.5 mm x 3.5 mm has a resilience loss of 5.8% and an area of 1.5 mm The resilience loss of the toothbrush with bristles fixed at 5 degrees inclined to the root of the x 4.0 mm was measured to be 4.2%.

As a result, it can be confirmed that the bristles having an area of 1.5 mm x 2.0 mm or more and inclined at 5 degrees have the most appropriate elastic loss value.

Referring to Table 3, it can be seen that the bristle removing area of the bristles of the conventional bristles fixed vertically to the circular bristle grooves and the bristles fixed at an angle of 5 degrees to the rectangular bristle grooves having various areas.

Unit: mm Diameter 1.6 + vertical bristles 1.0x2.5 + 5 degree inclined bristles Area 1.5x2.5 + 5 degrees inclined bristles Area 2.0x2.5 + 5 degrees inclined bristles Removal area of gingival softening plaque 2.59 ± 1.21 mm ² 6.11 ± 2.62 mm ² 5.25 ± 2.10 mm ² 2.83 ± 1.43 mm ²

The gingival drainage plaque removal area in Table 3 corresponds to the removal area of the artificial tooth surface bacterial membrane. The artificial tooth surface was coated with a polymer that colored the tooth part of the shape of the gingiva. Then, the bristles of the toothbrush were placed horizontally and the bristles of the coated model were placed horizontally, and the bristles of the toothbrush were covered to maximally cover the bristles of the bristles during brushing.

The vertical and horizontal strokes of each of the bristles were alternately performed every 30 seconds for a total of 8 times. The area before and after removal of the bacterial membrane on artificial tooth surface was measured using a microscope (ITplus microscope). Analysis of the collected data was made using the Window SPSS 20.0 statistical package program.

In Table 3, a conventional toothbrush equipped with bristles fixed vertically to a flute having a diameter of 1.6 mm had a tooth bristle removing area of 2.59. + -. 1.21 mm ² and an area of 1.0 mm x 2.5 mm, subgingival plaque removed area of the toothbrush is 6.11 ± 2.62mm ^2, and the area of 1.5mm x 2.5mm is implanted groove 5 also subgingival plaque removed area of the toothbrush to be inclined with a fixed brush is provided with a is 5.25 ± 2.10mm ² , And the area of gingival dental plaque removal of the toothbrush having bristles fixed at an inclination of 5 degrees to a flute of an area of 2.0 mm x 2.5 mm was measured to be 2.83 ± 1.43 mm ² .

As a result of the measurement of the area of removing the dental plaque as described above, it was confirmed that the bristles of the bristle grooves having the widths of 1.0 mm and 1.5 mm were twice as large as the bristles of the prior art. In addition, it was confirmed that the bristles of the bristles of the bristle grooves having a width of 1.0 mm as compared with the bristles of the bristle grooves having a width of 1.5 mm were wider than the bristles of the bristles.

As described above, the toothbrush 100 according to the embodiment of the present invention has a significantly higher effect of removing the gingival sagittal plaque than a conventional toothbrush using a bristle fixed vertically to a circular grooved groove at the time of brushing.

It will be apparent to those skilled in the art that various modifications, substitutions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims. will be.
