Description

The present invention relates to a periodontal pocket depth measuring device that measures the depth of a periodontal pocket.

In recent years, it has been reported that many people suffer from periodontal disease and diabetes without any subjective symptoms. Periodontal disease, in particular, is a illness that is too late to start treatment after having subjective symptoms such as swelling and bleeding gums, bad breath, or loose teeth, and is a scary illness that will surely cause teeth to fall out if left untreated. is there. On the other hand, it is possible to grasp the outline of periodontal disease by examining the depth of the periodontal pocket or the degree of sway of the tooth. Conventionally, as a method of measuring the depth of the periodontal pocket, a method of inserting the tip of the probe into the periodontal pocket and measuring the depth of the periodontal pocket by a scale provided on the probe has been used (for example). , Patent Document 1).

The inside of such a periodontal pocket is filled with periodontal disease bacteria, tissue fluid, bleeding components and the like. Therefore, since the probe inserted into the periodontal pocket is easily contaminated, it is necessary to disinfect and sterilize it before use. However, if the tip of the probe is not sufficiently disinfected and sterilized, it may contaminate the oral cavity of the person whose depth is to be measured in the next periodontal pocket. On the other hand, by replacing the probe every time the probe is used, it is possible to prevent the oral cavity of the person whose depth is measured in the periodontal pocket from being contaminated.

However, the conventional periodontal pocket depth measuring device has a problem that the cost increases when it is replaced every time it is used. For example, a metal probe costs 2,500 to 5,000 yen, and a plastic probe costs about 750 yen, which increases the cost when disposable. Further, when the periodontal pocket depth measuring device is made disposable, there is a problem that it may adversely affect the global environment.

Further, in the conventional periodontal pocket depth measuring device, the depth measurer of the periodontal pocket cannot visually check the inside of the periodontal pocket. Therefore, when there is tartar in the periodontal pocket, the tip of the probe is used. When it collides with the upper edge of tartar, it has a problem that it may be erroneously determined to be the bottom surface of the periodontal pocket and erroneously measured.

An object of the present invention is that it is possible to prevent the oral cavity from being contaminated by replacing it after use, and it is possible to suppress an increase in cost even when it is replaced after use, and it has an adverse effect on the global environment. It is an object of the present invention to provide a periodontal pocket depth measuring device capable of significantly suppressing the depth of the periodontal pocket and accurately measuring the depth of the periodontal pocket even when tartar or the like is attached to the tooth root.

The periodontal pocket depth measuring device according to the present invention is a periodontal pocket depth measuring device that measures the depth of the periodontal pocket, and is extended from the main body and the main body and inserted into the periodontal pocket. It has a plate-shaped probe, and the main body and the probe are integrally formed of paper.

When inserting the probe into the periodontal pocket for which you want to measure the depth, when the probe comes into contact with tartar or the like adhering to the periodontal pocket, it overcomes the tartar because it is formed of flexible paper. When it reaches the bottom of the periodontal pocket, the used periodontal pocket depth measuring device is discarded, and a new periodontal pocket depth measuring device is used at the next periodontal pocket depth measurement.

According to the present invention, it is possible to prevent the oral cavity from being contaminated by replacing it after use, and it is possible to suppress an increase in cost even when it is replaced after use, and it has an adverse effect on the global environment. It can be significantly suppressed, and the depth of the periodontal pocket can be accurately measured even when tartar or the like is attached to the tooth root.

The connecting portion 231 is not limited to a plate shape, but may be a semicircular shape.

<Operation of periodontal pocket depth measuring device>
The operation of the periodontal pocket depth measuring device 1 according to the first embodiment of the present invention will be described in detail below.

First, the insertion portion 21 of the probe 20 is inserted into the periodontal pocket for which the depth of the oral cavity is to be measured.

At this time, when there is tartar or the like in the periodontal pocket, the insertion portion 21 can get over the tartar without sticking to the tartar because the inclination angle of the inclined portion 211 is large. Further, since the insertion portion 21 has an inclined portion 211 having a wavy shape along the plate width direction or a shape having irregularities on the surface so that the surface has an arabesque pattern, the calculus adhering to the root surface is formed. It is possible to easily get over the upper edge, and it is possible to prevent plastic deformation and the like to improve the strength. When the inclined portion 211 has an uneven surface so as to have an arabesque pattern, it adheres to the tooth root surface as compared with the case where the inclined portion 211 has a wavy shape along the plate width direction. It is possible to make it easier to get over the upper edge of tartar.

Further, since the plate thickness of the connecting portion 231 of the curved portion 23 is smaller than the plate thickness of the portion of the curved portion 23 other than the connecting portion 231, the insertion portion 21 is easily deformed when the inserting portion 21 reaches the tartar. Can and can get over tartar. Further, since the insertion portion 21 is made of paper and is provided with the recess 212 and the recess 216, the insertion portion 21 can be made easy to bend, so that it is possible to easily get over the tartar.

When the teeth adjacent to each other have a contact portion, when measuring the depth of the periodontal pocket immediately below the contact portion, the probe 20 is periodontalized from an oblique direction while avoiding this contact portion. Must be inserted in the pocket. Therefore, the insertion portion 21 is inserted with the connection portion 215 as the tip in the direction of insertion into the periodontal pocket (hereinafter, referred to as “insertion direction”). At this time, by chamfering the connection portion 215, the pain associated with the insertion of the probe 20 into the periodontal pocket can be reduced.

Further, by making the inclination angle of the inclined portion 214 smaller than the inclination angle of the inclined portion 211 to suppress the size of the plate width, the inclined portion 214 is smoothly inserted into the periodontal pocket after the inclined portion 211 gets over the tartar. Can be inserted into.

Then, the tip surface 213 of the insertion portion 21 reaches the bottom of the periodontal pocket. At this time, when the insertion portion 21 reaching the bottom of the periodontal pocket is pressed in the insertion direction, the repulsive force from the bottom of the periodontal pocket causes the insertion portion 21 to be in the opposite direction of the insertion direction (hereinafter, simply referred to as "opposite direction"). To be described). The larger the pressing force in the insertion direction, the larger the pressing force is received by the inserting portion 21 in the opposite direction, and the received pressing force is transmitted to the curved portion 23. In the curved portion 23, the greater the pressing force in the opposite direction to the insertion portion 21, the smaller the distance between the opposite side portion 233 and the opposite side portion 234 facing each other through the gap 232, and the more the curved portion 23 is relative to the insertion portion 21. When a predetermined pressing force is applied in the opposite direction, the facing side portion 233 and the facing side portion 234 come into contact with each other as shown in FIG.

Here, the predetermined pressing force applied from the bottom of the periodontal pocket to the inserting portion 21 in the opposite direction is larger than the pressing force received by the inserting portion 21 from the tartar in the opposite direction. Therefore, the operator of the periodontal pocket depth measuring device 1 determines that the tip of the insertion portion 21 has reached the bottom of the periodontal pocket due to the contact between the facing side portion 233 and the facing side portion 234. be able to. At this time, by forming the connecting portion 231 into a plate shape, the insertion portion 21 side of the curved portion 23 is not twisted with respect to the gap 232 and the main body portion 10 side of the gap 232 is not twisted, so that the insertion portion 21 is smoothed. Can be inserted into the periodontal pocket.

When the operator of the periodontal pocket depth measuring device 1 determines that the insertion portion 21 has reached the bottom of the periodontal pocket, the operator visually measures the depth by visually observing the scale 29.

After the measurement of the depth of the periodontal pocket is completed, the insertion portion 21 is pulled out from the periodontal pocket. As a result, the pressing force transmitted from the insertion portion 21 to the curved portion 23 is released, and the facing side portion 233 and the facing side portion 234 face each other through the gap 232 due to the elastic recovery force of the paper. Return to the indicated state.

After this, the used periodontal pocket depth measuring device 1 is discarded. Next, when measuring the depth of the periodontal pocket, a new periodontal pocket depth measuring device 1 is used.

By forming the periodontal pocket depth measuring device 1 from paper, it is flexible because it has fibers, it is possible to prevent severe pain when it touches the gingiva, and it softens the calculus when it touches the calculus. You can get over it.

Incidentally, in order to alleviate the severe pain that occurs when the periodontal pocket depth measuring device is inserted into the periodontal pocket, it is conceivable to make the tip of the probe thinner to make it easier to bend, but the tip of the probe is made thinner. In some cases, severe pain will occur at the bottom of the gingiva. On the other hand, in the present embodiment, by forming the periodontal pocket depth measuring device 1 from paper, it is possible to easily cause bending without making the tip of the probe 20 extremely thin.

As described above, according to the present embodiment, the main body portion 10 and the plate-shaped probe 20 extending from the main body portion 10 and inserted into the periodontal pocket are integrally formed of paper for use. By replacing it later, it is possible to prevent contamination of the oral cavity, and even if it is replaced after use, it is possible to suppress an increase in cost and significantly suppress adverse effects on the global environment. In addition, the depth of the periodontal pocket can be accurately measured even when tartar or the like is attached to the tooth root.

(Second Embodiment)
<Configuration of periodontal pocket depth measuring device>
The periodontal pocket depth measuring device 2 according to the second embodiment of the present invention will be described in detail below with reference to FIGS. 6 and 7.

Since the periodontal pocket depth measuring device 2 has the same configuration as the periodontal pocket depth measuring device 1 except that it has a curved portion 33 instead of the curved portion 23 of FIGS. 1 to 5, other than the curved portion 33. The explanation of is omitted.

The curved portion 33 connects the insertion portion 21 and the base end portion 22, and is curved so that the insertion portion 21 and the base end portion 22 are located on the same plane. The curved portion 33 is provided on the inner peripheral side portion R1, and is a plate-shaped connecting portion 331 that connects the insertion portion 21 and the base end portion 22 and movably holds the insertion portion 21 with respect to the base end portion 22. And a gap 332 adjacent to the connecting portion 331 on the outer peripheral side portion R2, and a space 335 which is continuously provided in the gap 332 and widens from the gap 332 side toward the connecting portion 331 side. .. The curved portion 33 includes a facing side portion 333 and a facing side portion 334 facing each other through a gap 331.

The facing side portion 333 and the facing side portion 334 are inclined so as to be separated from each other as they are separated from the connecting portion 331 (as they move upward in FIG. 6). As a result, the facing side portion 333 and the facing side portion 334 can come into contact with each other on the entire surface as shown in FIG. 7 when the inserting portion 21 is pressed in the opposite direction. Further, by forming the space 335 so that the hem expands from the gap 332 side toward the connecting portion 331 side, it is possible to make it easier to move the facing side portion 333 and the facing side portion 334.

As described above, according to the present embodiment, in addition to the effect of the first embodiment, the insertion portion 21 is opposed to each other because the facing side portion 333 and the facing side portion 334 can be brought into contact with each other on the entire surface. When a predetermined pressing force is applied in the direction, the facing side portion 333 and the facing side portion 334 can be reliably brought into contact with each other.

The present invention is not limited to the above-described embodiment in terms of the type, arrangement, number, etc. of the members, and the constituent elements thereof are appropriately replaced with those having the same effect and effect, as long as the gist of the invention is not deviated.
