Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a device that uses electrolysis to clean teeth and dentition in the oral cavity and their prostheses, or apply or coat them with fluorine, etc. .

[Prior art]

This type of ril has a negative electrode attached to the nozzle or the bristled part of the toothbrush, and the gum side is used as the positive electrode to induce an electrochemical reaction through saliva or tap water. To prevent tooth decay, alveolar pus li, gingivitis, etc. by promoting the penetration of dental fluid into the tooth tissue, removing dental plaque, etc., or by stepping the oral cavity with chemicals mixed in tap water. A semiconductor with a photoelectric effect is attached to the flocked part of the brush, and by photoelectrically converting the light irradiated to this semiconductor, an oxidation reaction that releases electrons from saliva and water occurs around the semiconductor, and saliva and water around the teeth are generated. A reduction reaction that obtains electrons from water is generated to neutralize teeth whose pH has decreased due to plaque and tartar attached to the teeth, and prevent tooth demineralization caused by a decrease in pH. In addition, a device has been proposed that uses polarization to decompose dental plaque that causes cavities, thereby preventing cavities and alveolar pyorrhea and making teeth more beautiful.

However, since the conventional method 14 uses a nozzle or a toothbrush connected to tap water, it is not possible to sufficiently clean the teeth located in the back of the oral cavity or the narrow gaps between adjacent teeth. , it takes a lot of time (requires a lot of time).

Furthermore, it is almost impossible to apply or coat teeth with fluoride to prevent cavities.

[Purpose of the invention]

The present invention has been made in view of the above-mentioned problems, and its purpose is to clean plaque, tartar, etc. adhering to the periodontal surfaces of teeth and dentition without damaging the hard tissues of the teeth. The objective is to provide a device that can Another object of the present invention is to provide a device that can thoroughly clean teeth located deep in the oral cavity and narrow gaps between adjacent teeth, which has not been possible with conventional devices. Another object of the present invention is to provide an apparatus that can apply or coat fluorine or the like to teeth in a very elegant manner.

[Summary of the invention]

To achieve this purpose, the present invention provides an infiltrative insulator that covers a tooth or a row of teeth, and an anode and a cathode embedded in the infiltrative insulator, or only an anode embedded in the infiltrative insulator. and carrying the cathode around the tooth or dentition, impregnating the infiltrative insulator with a required solution containing at least an electrolyte beforehand or after coating the tooth or dentition, and applying a DC voltage to both electrodes. This foams the solution.

Hereinafter, the present invention will be described in detail along with examples.

〔Example〕

FIG. 1 is a perspective view showing an embodiment of the present invention. Reference numeral 1 denotes an infiltrative insulator made of a natural material such as cotton or a chemical substance such as polyurethane/foam, and the dentition (not shown) to be cleaned or coated is covered with the infiltrative insulator 1. Further, an anode 2 and a cathode 3 are buried in the infiltrative insulator 1 so as to face each other with the tooth row in between, and terminals 4 and 5 (not shown) are extended from both electrodes 2.3. Connected to DC power supply.

Note that when the wettable insulator l is impregnated with the solution described below,
In order to prevent the solution from leaking, a cover 6 made of insulating resin or the like is molded into approximately the shape of the tooth row is placed over the permeable insulator 1, or the cover 6 is filled with the permeable insulator 1 and then attached to the tooth row. FIG. 2 is a longitudinal cross-sectional view of the area indicated by ■-■ gland in FIG. It shows.

21 is the gum. Moreover, FIG. 3 is a plan view of FIG.
It shows a state in which they are buried so as to face each other with rows (not shown) in between.

In this embodiment, the cover 6 was used to prevent the leakage of the solution impregnated into the wettable insulator 1. However, if a more efficient and economical configuration is shown, the wettable insulator 1 may be a fresh water-based solution, for example. A polymeric resin material that is easy to mold, such as polyurethane foam, is preferably used, and is foamed into the cover 6 in the shape of a row of teeth, and the wettable insulator 1 and the cover 6 are integrally molded, or
If the insulating insulator 1 is foamed in a mold formed in the shape of an approximately tooth row, and the outer peripheral surface of the insulator 1, that is, the part corresponding to the cover 6, is finished in a water-permeable state, the cover 6 as described above becomes unnecessary. It can be made economically, is disposable, and is hygienic.

A suitable polymeric resin material for the wettable insulator 1 is, for example, incyanate-blocked polyoxyethylene disclosed in JP-A-51-111792 as "Dental or Medical Foam". There are hydrophilic crosslinked polyurethane foams made by reacting polyols with large amounts of water-soluble reactants. When this foam is compressed, it maintains its size until it is used, and when it comes into contact with a solution, it returns to its original size. Therefore, after foaming this foam into the shape of the tooth row, if the part where the tooth row is inserted is compressed, it can be easily attached to the tooth row, and when in use, it will come into contact with the solution and the foam will come into contact with the tooth row without any gaps. and be effective. In each of the above embodiments, the case where the anode 2 and cathode 3 were buried in the permeable insulator l was explained.
The arrangement of i can be modified in various ways. FIG. 4 is a cross-sectional view corresponding to FIG. 2, showing an embodiment of the modified electrode arrangement. In this figure, parts corresponding to those in FIG. 2 are given the same reference numerals and their explanations will be omitted. 12
are anodes, respectively, and 13 is a cathode which also serves as the cover 6 (Fig. t42). With this configuration, the anode! By increasing the number of bubbles 2, it becomes possible to arrange the bubbles uniformly in the wettable insulator i.

In addition, when cleaning or coating the teeth or tooth rows of the upper and lower jaws at the same time, it is sufficient to combine the teeth shown in Fig. 1 or 4 vertically, or to mold the upper and lower parts as one piece. The present invention also includes cases where the invention is carried out in this manner.

[Action of the invention]

When the wettable insulator 1 of the device configured as described above is impregnated with a solution containing the substance to be cleaned, coated, or applied and an electrolyte, and a DC voltage is applied between the anode 2 and the cathode 3, the solution is It is foamed by the electrolytic action and can be brought into full contact with the tooth or dentition through the pores of the wettable insulator 1 for the desired cleaning, coating or scrubbing.

An example will be described in which a solution containing water molecules as the main component is used. Water is a good solvent for many substances,
It is well known that when electrolysis is performed, hydrogen gas is generated from the cathode side and oxygen gas is generated from the anode side, and the amount of gas generated can be controlled by appropriately selecting the overvoltage. The purpose is to utilize this gas as a foaming source for the desired solution.In order to increase the foaming effect, a viscous solute should be appropriately dissolved in water, and the dissolution reaction on the anode 2 side , and a precipitation reaction occurs on the cathode 3 side. Therefore, for the anode 2, an insoluble gold layer such as stainless steel is used, and for the cathode 3, a material having good electrical conductivity to the solution, such as platinum, is used. It is preferable to use

When applying or coating tooth surfaces with, for example, fluorine using the device of the present invention, cleaning with a cleaning agent is performed as a preliminary treatment, but this cleaning and subsequent application or coating are also performed by impregnating with the respective solutions. By preparing the wettable insulator 1 separately,
