Background Art

[0009] The embodiments of the present invention will be described below. The embodiments shown below are one aspect of the present invention and do not limit the technical scope of the present invention.

[0010] <Embodiment 1> The oral sheet according to Embodiment 1 will now be described. Figure 1 is a cross-sectional view showing the oral sheet according to Embodiment 1 in use. The oral sheet 1 is fixed to the user's mandibular molar tooth 100 and the gum 101 below it. By being fixed across the tooth 100 and the gum 101, the oral sheet 1 penetrates the caries-causing bacteria on the surface of the tooth 100, the gum 101, and tartar inside the periodontal pocket 102, killing bacteria and promoting an anti-inflammatory effect.

[0011] Figure 2 is a plan view showing an oral sheet according to Embodiment 1. The oral sheet 1 comprises a sheet base material 2 that can be fixed in the oral cavity and an oral composition 3 attached to the surface of the sheet base material 2. For example, a suitable resin can be selected and used as the material for the sheet base material 2. When viewed from above, the sheet base material 2 has a rectangular shape with chamfered corners, and the oral composition 3 is attached to the central side of the sheet base material 2. The sheet base material 2 has an adhesive portion 4 arranged around the oral composition 3 that can be attached to the user's gums or teeth. The adhesive portion 4 may be adhesive, or it may be fixed in the mouth by adhering to the teeth 100 or gums 101 when it comes into contact with the user's saliva. The oral composition 3 is a combination of anti-inflammatory components (dipotassium glycyrrhizinate) that kill periodontal disease bacteria, bactericidal components (hinokitiol, cetylpyridinium chloride hydrate, isopropylmethylphenol), etc. Furthermore, the oral composition 3 is preferably in gel form so that it can quickly reach and remain inside the user's periodontal pocket 102, thereby enabling effective sterilization. The oral composition 3 dissolves over time in saliva or at body temperature. The sheet base material 2 may dissolve in saliva or at body temperature after the effective time of the oral composition 3 has elapsed, or more specifically, after the sheet base material 2 has been fixed in the mouth and the medicinal effect time (pharmacokinetic time) of the oral composition 3 has elapsed, it may dissolve in saliva or at body temperature.

[0012] The oral sheet 1 according to this embodiment can be easily fixed in the mouth and can partially care for the teeth 100 and gums 101. Furthermore, as shown in Figure 1, by fixing the oral sheet 1 in the mouth so as to cover the periodontal pocket 102 from the teeth 100, the inside of the periodontal pocket 102 can be effectively sterilized.

[0013] Further, the sheet base material 2 may be colored so that the whole has the same color as teeth or gums. For example, when the sheet base material 2 is fixed in the mouth so as to cover only the teeth, the sheet base material 2 may be colored white to the same extent as the teeth. When the sheet base material 2 is fixed in the mouth so as to cover only the gums, the sheet base material 2 may be colored white to the same extent as the gums. When the sheet base material 2 is fixed in the mouth so as to cover both the teeth and the gums, the upper half of the sheet base material 2 may be colored white to the same extent as the teeth, and the lower half of the sheet base material 2 may be colored white to the same extent as the gums. By coloring the sheet base material 2 according to the fixing position in this way, the sense of incongruity in appearance when using the oral sheet 1 can be reduced.

[0014] <Modification Example 1> FIG. 3 is a plan view showing the oral sheet 1 according to Modification Example 1 of Embodiment 1. The oral sheet 1 according to Modification Example 1 is for front teeth and is formed in a stepped planar shape with a narrow upper side and a wide lower side so that the sheet base material 2 can be easily fixed to the user's front teeth. The oral composition 3 is attached to the central side of the sheet base material 2, and the periphery of the oral composition 3 becomes the sticking portion 4. Thus, the oral sheet 1 may be formed in an appropriate shape according to the use location. Further, in the oral sheet 1 according to this modification example, the oral composition 3 may be fixed in the mouth so as to cover only the teeth, may be fixed in the mouth so as to cover across the teeth and the gums, or may be fixed in the mouth so as to cover only the gums.

[0015] <Embodiment 2> Next, the oral sheet according to Embodiment 2 will be described. FIG. 4 is a cross-sectional view when the oral sheet according to Embodiment 2 is cut along the longitudinal direction. The oral sheet 1 according to the present embodiment has the same planar shape as the oral sheet 1 according to Embodiment 1 shown in FIGS. 1 and 3.

[0016] In the present embodiment, a plurality of layers of the oral composition 3 are formed on the sheet base material 2. Overall, the oral composition 3 has a first layer 3A containing a tooth whitening agent on the side of the sheet base material 2, and a second layer 3B containing an active ingredient for sterilizing dental caries or periodontal bacteria laminated thereon. As shown in FIG. 1, the oral sheet 1 according to the present embodiment is assumed to be fixed in the oral cavity across the teeth and the gums. After the second layer 3B sterilizes the teeth and the gums, the first layer 3A dissolves and the drug elutes, so that the first layer 3A can perform tooth whitening. Thus, by forming the oral composition 3 into multiple layers and forming layers for each use of the drug, the oral sheet 1 can be used for multiple types of oral care.

[0017] Also, the first layer 3A and the second layer 3B have different components so that the drug elutes with a time difference when they are touched by saliva or warmed to about body temperature. For example, when the second layer 3B contains a drug for tooth cleaning and sterilization, at the beginning of wearing the oral sheet 1, the drug for tooth cleaning and sterilization elutes from the second layer 3B to repair the tooth function, and the whitening function of whitening the teeth by the elution of the whitening drug from the first layer 3A may be exhibited. Further, a fluorine coating agent may be included in the first layer 3A so that the fluorine coating agent elutes after the tooth cleaning and sterilization are completed, and the fluorine coating is performed after the teeth are in a clean state.

[0018] <Embodiment 3> Next, the oral sheet according to Embodiment 3 will be described. FIG. 5 is a plan view of the oral sheet according to Embodiment 3, and FIG. 6 is a cross-sectional view of the oral sheet when cut along the line A-A in FIG. 5.

[0019] In the oral sheet 1 according to this embodiment, the sheet base material 2 has a return portion 5 that surrounds the outer circumference and extends toward the user's teeth. The return portion 5 extends from the end of the sheet base material 2 toward the user's teeth. An adhesive portion 4 is provided on the outer surface of the return portion 5. When the oral sheet 1 according to this embodiment is fixed in the mouth, the adhesive portion 4 on the outside of the return portion 5 can be attached to the teeth or gums, and in this state, it is possible to prevent the dissolved oral composition 3 from leaking out of the oral sheet 1.

[0020] <Embodiment 4> Next, an oral sheet according to Embodiment 4 will be described. Figure 7 is a plan view of the oral sheet according to Embodiment 4. The oral sheet 1 according to this embodiment is divided into three regions R1, R2, and R3, as shown by the imaginary lines L1 and L2 extending along the longitudinal direction of the sheet base material 2. The upper region R1 is the region to be aligned with the teeth, the central region R2 is the region to be aligned with the periodontal pocket, and the lower region R3 is the region to be aligned with the gums. In the oral sheet 1 according to this embodiment, the sheet base material 2 is colored differently in each region, and the user can visually confirm which color region to align with which position in the oral cavity by referring to the instruction manual or other means.

[0021] Furthermore, the oral sheet 1 may contain different components of the oral composition 3 placed in each region. For example, region R1 may contain an agent for preventing hypersensitivity or a whitening agent, region R2 may contain an agent for preventing hypersensitivity or a periodontal disease prevention agent, and region R3 may contain an agent for preventing hypersensitivity or a gum inflammation prevention agent. In this way, by changing the agents contained in the oral composition 3 for each region, the oral sheet 1 can perform multiple oral care procedures. In addition, the oral sheet 1 may be divided into two regions with different agents contained in each region, or it may be divided into four or more regions with different agents contained in each region. In this embodiment, even if the agents placed in each region of the oral sheet 1 are different, by using different colors for each region on the sheet base material 2, it is easy to align the agent within each region, and the agent suitable for the teeth, gums, periodontal pockets, etc., can be placed in the desired position. It can be fixed in place inside the mouth so as to make contact. Therefore, the oral sheet 1 can provide effective oral care.

[0022] Furthermore, in the oral sheet 1, the oral composition 3 may be formed in different layers in each region. For example, in region R1, an anti-sensitivity agent and a whitening agent may be placed in separate layers; in region R2, an anti-sensitivity agent and a periodontal disease prevention agent may be placed in separate layers; and in region R3, an anti-sensitivity agent and a gum inflammation prevention agent may be placed in separate layers. By laminating these layers to form the oral composition 3, the oral sheet 1 can perform oral care using different agents over time.

[0023] Furthermore, in the oral sheet 1, the adhesive properties of the adhesive portion 4 may differ in each region. For example, in region R1, the adhesive portion 4 may be formed with an adhesive that adheres easily to the teeth and not easily to the gums, while in region R3, the adhesive portion 4 may be formed with an adhesive that adheres easily to the gums and not easily to the teeth. By using different adhesive materials for each region in the adhesive portion 4 in this way, it is possible to prevent the oral sheet 1 from being fixed in the mouth with the dental medication in contact with the gum side and the medication for preventing gum inflammation only in contact with the teeth. This prevents the oral sheet 1 from being fixed in the wrong position, enabling effective oral care.

[0024] Furthermore, the oral sheet 1 has a different texture for each region R1 to R3, or a fold along the boundary between regions R1 to R3, making it easier for the user to distinguish between the regions. The oral sheet 1 prevents being fixed in the wrong position, allows the adhesive function to be fully exercised, and allows the medication to remain on the affected area for the appropriate time.

[0025] <Embodiment 5> Next, an oral sheet according to Embodiment 5 will be described. Figure 8 is a plan view of the oral sheet according to Embodiment 5. In this embodiment, the oral sheet 1 does not have the oral composition 3 attached to the sheet base material 2 in advance, and the oral composition 3 is applied to the sheet base material 2 immediately before use. The oral sheet 1 is used by placing the oral composition on the sheet base material 2 or by applying the oral composition to the tooth side of the sheet base material 2. In this embodiment, the entire tooth side of the sheet base material 2 is the adhesive portion 4.

[0026] Furthermore, in this embodiment, similar to embodiment 4 described above, the sheet base material 2 is divided into three regions R1, R2, and R3 as indicated by virtual lines L1 and L2 extending along its longitudinal direction. The upper region R1 is the region aligned with the tooth portion, the central region R2 is the region aligned with the periodontal pocket, and the lower region R3 is the region aligned with the gums. In the oral sheet 1 according to this embodiment, the sheet base material 2 is colored differently in each region, and the user can visually confirm which colored region should be aligned to which position in the oral cavity by referring to the instruction manual or other means.

[0027] Furthermore, in the oral sheet 1, the adhesive performance of the adhesive portion 4 may differ in each region. For example, in region R1, the adhesive portion 4 may be formed with an adhesive that adheres easily to the teeth and not easily to the gums, while in region R3, the adhesive portion 4 may be formed with an adhesive that adheres easily to the gums and not easily to the teeth. By using different adhesive materials for each region in the adhesive portion 4 in this way, it is possible to prevent the oral sheet 1 from being fixed in the mouth with the dental medication in contact with the gum side and the gum inflammation prevention medication in contact only with the teeth. This prevents the oral sheet 1 from being fixed in the wrong position, enabling effective oral care. As in this embodiment, by using different adhesive components for each region, it is possible to form an adhesive portion 4 that is suitable for the object to which it is to be applied.

[0028] Furthermore, at both ends in the width direction of the sheet base material 2, the adhesive portion 4 may be formed to adhere closely to the teeth and gums. With this configuration, the oral sheet 1 is positioned on the center side in the width direction. By applying composition 3 and ensuring that both ends of the sheet substrate 2 in the width direction are in close contact with the teeth and gums, it is possible to suppress saliva from entering the oral sheet 1, preventing the oral composition 3 from flowing out and the adhesive strength of the attachment portion 4 from weakening. Furthermore, the sheet substrate 2 may have liquid impermeability to prevent the oral composition 3 from permeating to the tooth side and to prevent saliva from permeating to the tooth side.

[0029] <Other Embodiments> In the above embodiment, an example of use was shown in which the oral sheet 1 is fixed from the teeth to the gums, but the oral sheet 1 is not limited to this. For example, if the oral composition 3 contains only a drug targeting teeth, it is preferable that the oral sheet 1 be fixed in the oral cavity so that the oral composition 3 is in contact only with the teeth. Also, for example, if the oral composition 3 contains only a drug targeting gums, it is preferable that the oral sheet 1 be fixed in the oral cavity so that the oral composition 3 is in contact only with the gums.

[0030] Furthermore, in embodiments 1 to 4 described above, the oral composition 3 is pre-attached to the sheet base material 2, but it is also possible to apply the oral composition 3 to the sheet base material 2 immediately before using the oral sheet before using it. The oral composition 3 may be separately filled into a tube or the like, and the oral care kit may consist of the sheet base material 2 and the tube filled with the oral composition 3.

[0031] The features included in each embodiment and its modified form disclosed above can be combined in any way. [Explanation of Symbols]
