Description
Technical field
The invention belongs to whitening field, and in particular to a kind of bleaching agent and its method for bleaching.
Background technology
In recent years, in terms of beauty, the pigment (i.e. so-called whitening) for removing tooth and skin has caused extensive concern,
But whitening product on the market has the defects of certain, thus must further integrate improve bleaching agent blanching effect and its
Security.The demand for such as improving tooth contour, Dental Aesthetic as arrangement and integrality improves is existed in tooth therapy
It is stepped up.Particularly there is demand to make teeth whiter in women young in more situations to this kind of tooth therapy
For the important component of beauty.
In general, tooth discoloration or pigmentation or pollution the reason for belong to following classes：(1) external cause, such as
The deposition of coloring matter (tobacco, tea, pollutant etc.), the pigment for producing bacterium, filler (mainly composite resin) and gold
Belong to the discoloration of salt (mainly mercury alloy, silver nitrite and ammonia silver)；(2) internal cause, such as aging, chemical substance or medicine
(such as fluorine, tetracycline etc.), dysbolism and heredity and injury of teeth.
The position that the reason for skin is also exogen or endogenous is easily colored.As the coloration reason of external cause,
There is the coloring of the calmness, pigment generation bacterium of coloring matter；As the coloration reason of endogenous, has age increase, pigment deposition, generation
Thank exception and genetic disease, the injury of skin etc..
However, in the bleaching agent of routine or method, main bleaching agent is that 30wt%-35wt% hydrogen peroxide is water-soluble
Liquid and its oxidation characteristic are the bases of bleaching teeth.Therefore, had difficulties in terms of ease of handling and security.In the presence of use
10wt% urea peroxides solution substitutes other method for bleaching of 30wt%-35wt% aqueous hydrogen peroxide solution；However, this method
The problem of in terms of there is also medical efficacy and security.
In existing method, Japanese correlative study person has found：It is splendid as being showed in terms of security and simplification
And to must tooth and nonessential tooth show remarkable efficacy in a short time and without using highly toxic 30wt%-35wt% mistakes
Aoxidize the new bleaching agent and method for bleaching of aqueous solution of hydrogen:Titanium dioxide and low concentration peroxide with photocatalysis is applied in combination
It is effective to change the bleaching agent of aqueous solution of hydrogen；However, the storage stability of dental bleaching agent and inadequate；20% hydrogen peroxide into
Divide after being stored 1 month in the refrigerator of 5 DEG C~8 DEG C temperature shielded (varnishes)；In addition, show by because of thickener
Effect reduces and causes to apply the insufficient situation generation of difficult and caused bleaching effect in dental surface；Therefore, it is necessary to have
There is the preferable dental bleaching agent of storage stability.
Hereafter Japanese correlative study person has invented the formula of bleaching agent, configuration technique and application method in more detail.But
Scheme of this method due to having used A, B agent, before Clinical practice mix rear can be used, be just inevitably generated with
Lower problem points：
1st, due to having used the scheme of A, B agent, manually mixed before Clinical practice, just necessarily cause bleaching agent denseness not
Greatly, easily slid from tooth.
2nd, due to having used A, B agent so that the hydrogen peroxide keeping concentration of the A agent containing hydrogen peroxide increases at double, and
This legal restriction transported certainly again.
3rd, A, B agent manually mixes before Clinical practice, cause medicament mixing it is uneven, have impact on effect.Increase doctor
The workload of business personnel.
Existing technology has proposed that a variety of methods, but, can as the aesthstic ameliorative way to discored tooth and skin
A certain degree of color reversal etc. can be present.This method for bleaching substantially takes off coloring matter by chemical reaction
The method of color.Have in the past various on including various chemical substances based on required method for bleaching and nonessential method for bleaching
Bleaching agent and using this kind of reagent method for bleaching report.
The content of the invention
In order to solve various problems existing for bleaching agent in the prior art, the invention provides a kind of bleaching agent, overcome
Above-mentioned problem of the prior art, there is good extended storage stability, be easy to be applied in discoloration in actual applications
Tooth on and obtain enough bleaching effects without declining original photocatalytic activity, in addition in terms of security
It is splendid.Present inventor is directed to combining the research of above-mentioned bleaching agent and being subsequently found contains inorganic thickening in bleaching agent
Agent and phosphoric acid, it is easy to that gratifying bleaching effect is applied on discored tooth surface and have also obtained in practical application
It is also splendid in terms of security in addition without declining original photocatalytic activity；Stabilizer is added, can be improved long-term
Storage stability.
