Description

SPECIFICATION Toothbrush with the effect of preventing deposition of tartar and other incrustation of the teeth Background of the Invention Field of the Invention The present invention relates to a toothbrush with the effect of preventing deposition of tartar and other incrustation on the teeth, as the result of generating magnetic or electric field in the surroundings of the bristle part of the toothbrush to change the distribution of electrochemical potential or electric charges.
Description of the Prior Art Tartar may be considered to be formed in the following electrochemical process: Foods ingested into the mouth are masticated in the presence of salivary secretion. The residue of mastication product in the mouth, which are possibly so minute particles as insensible by the nerves distributed on the oral parts, deposits on the teeth, initially in the form coating consisting of a yogurtlike paste, and in the lapse of time converts into tartar or incrustation containing calcium phosphates. The incrustation, which is regarded as an electrochemical process, could not proceed rapidly without participation of ion-change, migration of electrolysis.
Attention is paid also to the process of forming tartar in which the deposition occurs not onto the gum but preferentially on to native and artificial teeth so firmly as not to be readily clean off.
Although soft material has property to undergo deposition on it with difficulty, what does cause deposition onto the smooth upright surface of the teeth? The phenomenon supports the possibility of participation of ion-exchange, migration of electric charges and electrolysis in the process of forming tartar.
From the above-described, if salivary secretion and the gum tissue had electric charge opposite to that of the bony tissue, it would be reasonable that the residue of minute particles carrying negative charge can be deposited onto the bony tissue.
Metallic crowns such as gold or silver crown on the teeth becomes not very much dirty because they are a good electric conductor. On the contrary, material of low electric conductivity or insulator such as bone is of course chargeable. As well-known, there is attraction, repu.sion or neutralization associated with discharge between charged objects.
Tartar can be found also on the artificial gum of synthetic resin and this suggests that tartar may grow by making use of an insulator as a base.
Once the minute-particulate residue containing Ca, P. Protein under the action of salivary secretion deposits on the tooth, they serve as a dielectric medium between salivary secretion of pH 9-11 and the tooth, thus a condensor-like device with difference of potential between them being formed. Thereafter in virtue of the difference of potential, accumulation of tartar goes on.
It is interesting that alkaline water with high concentration of OH-, the so-called ion water is said to have a preventing effect against the deposition of tartar. The effect is considered to be taken by the following mechanism: The bony tissue carries positive charges whereas the residual paste is negatively charged. Such distribution of electric charges leads to the attraction of the residual paste to the surface of the tooth. When strong-alkaline water is held in the mouth, metallic components in the alkaline water, such as Ca++ neutralize the negative charges on the paste. Thus the paste becomes discharged and released from the attraction by the positive charges on the tooth, reflecting easier clearance off residual paste.
The process of forming tartar is as abovedescribed. Though effects of magnetic field on such process is under experimental study, the concept is likely to be established that ion current in the living body can be affected by magnetic field.
Summary of the Invention in the mouth is always found respective electric charges or potentials to the bony teeth, the gum tissue and salivary secretion containing mucin.
The distribution of electric charges or potential is extremely complex or tangled and transitional because of too many parameters for determining it, such as ingested foods, drinks and air, chewing and involving friction etc. In particular, during chewing motion is induced, in the mouth, confusion of positive and negative charges compared with usual electrical conditions, and, as the result, neutralization between them.
The toothbrush according to the invention with magnetic field generating means is expected to take two effects: One is the effect of making electrostatic field disappear by the action of magnetic field. In the report on the use of magnet for aligning the teeth set, it is described that the use of magnet prevented the clinging of bacteria inducing decayed teeth. This may mean that magnetic field would cause the distribution of potential or electric charge in the mouth to change, resulting in preventing from bacteria in salivary secretion from clinging on the teeth. Based on the inference, magnetic field generated by the toothbrush according to the invention would exert the effect of changing in the distribution of potential to make the clearance easier.Taking the occurrence of static electricity by the friction between teeth and a toothbrush into consideration, it also may be expected to take the effect of making electrostatic field vanish by the action of magnetic field, although there is room for study.
The other is the effect of clearing off the paste into water. In the mouth, of course, too strong current should not be applied to avoid any adverse effect. The experiment demonstrated that currents of not more than 20 ,u,A or voltages of not more than 1.5 V cannot make the taste unnatural. A toothbrush manufactured for trial is provided with an alkaline storage battery for a table electronic computer (11.5 #, supply current ranges: 1-5 juA and stainless wires leading to the electrodes of the battery, these being held in the inside of the brush handle body so as not generate static electricity.
Without needing switch, electric current, when bristles of the toothbrush get wet, flows between the electrodes to cause electrolysis, associated with formation of different ions. The salt is allowed to react with H20 and converts into H2, Cl2 and NaOH. Chlorine (Cl2) serves as bactericide and bleaching agent whereas NaOH have a cleasing effect but the amounts of these are only a little.
Inevitably, the distribution of electric charges in the mouth is changed and thus effect of clearing off the residual paste into water can be expected.
