Description
The invention relates to a medicine, in particular to a tooth bleaching preparation for treating pigment teeth such as tetracycline pigmentation teeth, fluorine teeth and the like.
As a result of the abuse oftetracycline for a long time in China, the incidence of tetracycline teeth reaches 86.11% of rural students and 78.50% of urban students in China. As the fluorine content in drinking water and soil in many areas is too high in China, the morbidity of the fluorine-containing Babinya in China is quite high and reaches 69.6 percent. Both of these pigmented teeth seriously affect the aesthetic appearance of the patient. With the improvement of the material culture level of people, more and more patients are required to decolor and beautify teeth. A commonly used bleaching agent today is hydrogen peroxide. Hydrogen peroxide is a strong oxidant, and has unstable performance and short effective action time. The imported bleaching agent is carbamide peroxide, and the bleaching principle is that the carbamide peroxide is decomposed to generate hydrogen peroxide to play a role. After decomposition of carbamide peroxide, hydrogen peroxide is produced, and some substances harmful to human body such as carbamide, ammonia, carbon dioxide, etc. are produced. The quality of the products in China is difficult to guarantee, and the price of imported products is high.
In recent years, some companies such as Xian, Sichuan and Tianjin in China produce tooth bleaching gel, and the main component of the tooth bleaching gel is carbamide peroxide; the traditional bleaching agent is hydrogen peroxide, which is a strong oxidant, has rapid decomposition and short action time, can only be used in medical rooms of hospitals and clinics, and has poor curative effect and inconvenient use.
The invention aims to avoid the defects in the prior art and provide the tooth bleaching gel which has long treatment time, good treatment effect, no side effect on human body, low price and convenient use at home.
The invention is composed of:
the method is characterized in that the advantages and the disadvantages of various bleaching agents in China and China are integrated, repeated tests and comparison are carried out on various peroxides such as peroxybenzoic acid, carbamide peroxide, hydrogen peroxide and the like, finally, hydrogen peroxide is selected as a main raw material, in order to ensure the stable performance of the bleaching agent, a certain amount of quinine hydrochloride is added as a stabilizer (quinine hydrochloride has good anti-reduction reaction capability and can play a role in stabilizing peroxide), and auxiliary components such as glycerol, gelatin, Carbopol glue and phosphoric acid buffer solution are added, and the bleaching agent is processed properly to form viscous paste. The paste has neutral pH, translucence, strong viscosity, slow release of oxygen free radicals, safe use, good bleaching effect and low price. Since urea peroxide is not contained, amine ions harmful to the body are not released by decomposition, and the urea peroxide is harmless to the body even if not swallowed.
The main component of the household tooth bleaching gel is hydrogen peroxide, and the household tooth bleaching gel is characterized in that a quinine hydrochloride stabilizer is added in the bleaching gel, and the specific components and the formula (weight percent) are as follows:
the main components are as follows: (1) 10-15% of hydrogen peroxide.
(2) Quinine hydrochloride 0.5%
Auxiliary components: a. 65 to 70 percent of glycerin
b. 2 percent of gelatin
c. Carbopol (Carbopol) 1%
d. 12 to 22 percent of phosphate buffer solution
The production method of the household tooth bleaching gel comprises the following steps:
mixing the auxiliarycomponents a, b, c and d, stirring, heating in microwave oven at 80-85 deg.C to melt to obtain viscous paste, adding the main components 1 and 2 under stirring, cooling, and packaging in nontoxic plastic tube with cover.
The following steps: hydrogen peroxide (AR, 30%, manufactured by Guanghua chemical company, Zhengzhou city); quinine hydrochloride (produced by Shanghai pharmaceutical company), phosphate buffer (self-made), and other auxiliary components are commercially available products.
Example 1: with hydrogen peroxide (H)2O2) The household tooth bleaching gel prepared from 10 percent of quinine hydrochloride, 0.5 percent of phosphate buffer solution, 65 percent of glycerol, 2 percent of gelatin and 1 percent of carbopol has obvious clinical effect. If the hydrogen peroxide concentration is gradually reduced, the clinical effect of the bleaching gel is gradually reduced.
Example 2: the household tooth bleaching gel prepared from 14.5% of hydrogen peroxide, 0.5% of quinine hydrochloride, 12% of phosphate buffer, 70% of glycerol, 2% of gelatin and 1% of carbopol has good clinical effect because the hydrogen peroxide concentration is increased and the nascent oxygen is increased.
Quinine hydrochloride is a polynuclear aromatic compound which takes nitrogen-containing naphthalene as a main structure and has a side chain. The compound has two characteristics: (1) aromatic anions can be generated in an inert solvent or under air-isolated conditions when a reducing agent is encountered: (2) when the hydrocarbyl group reacts with oxygen, an inactive peroxide radical is generated: . These two properties, either in the presence of a reducing agent or in the presence of oxygen, favor the formation of free radicals for peroxides, and the presence of excess free radicals can hinder the nascent oxygen formation or free radical formation of peroxides.
The formation of free radicals is slowed down by the addition of a suitable amount of quinine hydrochloride to the hydrogen peroxide. The bleaching mechanism of hydrogen peroxide is: the free radicals can penetrate through enamel to chemically react with pigment groups in dentin, so that the color of the dentin is changed to achieve the aim of bleaching. Therefore, the addition of quinine hydrochloride to the hydrogen peroxide can prolong the effective bleaching time by 4 to 6 times.
The american scholars Haywood and Heymann, 1989, first reported bleaching of pigmented teeth with 10% carbamide peroxide, the mechanism of carbamide peroxide bleaching is via the action of hydrogen peroxide generated by decomposition of carbamide oxide, which, in addition to hydrogen peroxide, generates harmful substances such as urea, carbon dioxide, ammonia, etc. The quality of the products in China is difficult to guarantee, and the price of imported products is high.
Through literature search, no report is found about adding quinine hydrochloride as a stabilizer into a bleaching agent taking hydrogen peroxide as a main component in a formula of the tooth bleaching gel at home and abroad.
The household tooth bleaching gel produced according to the components and the formula is prepared by the steps of: as a result of toxicity test, the tooth bleaching gel has no morphological influence on heart, liver, spleen, lung, kidney, esophagus, oral mucosa and the like of animals; the result of stimulation test shows that the tooth bleaching gel has no stimulation reaction to oral mucosa, esophageal mucosa and squamous epithelium of animals; as a result of allergy test, the tooth bleaching gel did not show delayed allergic reaction to animals.
The tooth bleaching gel prepared from hydrogen peroxide and quinine hydrochloride as main ingredients is used for treating tetracycline, fluorine teeth, and various pigment teeth with exogenous pigment deposited on teeth such as cigarette, tea, colored beverage, food, etc. The patient can provide necessary appliances under the guidance of doctor by medical unit, and the tooth bleaching gel is taken home for self-treatment, so the tooth bleaching gel is called as household tooth bleaching gel. The product can be preserved at low temperature below 4 deg.C for a long period.
The household tooth bleaching gel is a viscous paste, the pH of the paste is neutral, semitransparent, non-flowing, free of peculiar smell, moderate in viscosity, capable of slowly releasing oxygen free radicals, stable in bleaching performance, long in validity period, good in curative effect, free of stimulation to oral mucosa, free of anaphylactic reaction, free of toxic and side effects, safe and convenient to use, low in medium (70% lower than that of an imported product), and suitable for being used by a patient for birth.
The morbidity of pigment teeth such as tetracycline pigmentation teeth, fluorine plaque teeth, tobacco and tea stain teeth and the like in China is high, the appearance of a patient is seriously affected by various pigment teeth, and particularly young people cannot completely remove yellow teeth and dirty teeth and replace complete dentures. With the improvement of living standard and social interaction activities of people, health and beauty have gradually become hot spots pursued by people. According to survey and statistics, about two hundred million people exist in nationwide patients with various pigment teeth, so that the household tooth bleaching gel has wide popularization and application prospects.
