Embodiment 1～9

[0027] The second reagent was added to the first reagent shown in Table 1, and mixed for a certain period of time to obtain tooth bleaching materials prepared separately.

[0028] Table 1

[0029]

Embodiment 10

[0031] The tooth bleaching material obtained in Example 3 was diluted with purified water, and the pH was adjusted with NaOH to obtain tooth bleaching with a total active oxygen content of 1.3% (1.8% by mass of peroxymethylsuccinic acid, 2.3% by mass of hydrogen peroxide) and a pH of 5. Material.

Embodiment 11

[0033] The pH of the tooth bleaching material obtained in Example 7 was adjusted with NaOH aqueous solution to obtain a tooth bleaching material with a total active oxygen content of 1.1% (peroxysuccinic acid 1.9% by mass, hydrogen peroxide 1.9% by mass) and a pH of 6.

Abstract

A tooth-bleaching material characterized by comprising: hydrogen peroxide and / or a compound which generates hydrogen peroxide in an aqueous solution; a dicarboxylic acid anhydride; a basic compound; and a thickener. Also provided is a method of tooth bleaching characterized by adhering the tooth-bleaching material, optionally after being diluted, to the surface of a stained tooth and irradiating it with light. Thus, the coloring matter (coloration, discoloration) deposited on a tooth is bleached and removed. The tooth-bleaching material is safe and convenient for use and has a high bleaching effect. The method of tooth bleaching employs the tooth-bleaching material.

Description

technical field [0001] The present invention relates to a bleaching material capable of bleaching and removing pigment (staining, discoloration) deposited on teeth and a method of bleaching teeth. Background technique [0002] In recent years, there has been an increasing demand for aesthetic improvement in the form, arrangement, and coordination of teeth in dental treatment. In particular, cases of young women seeking dental treatment for tooth whitening, which is an important factor in beauty, are increasing. [0003] The bleaching materials for teeth are required to meet the following conditions: (a) significant bleaching effect, (b) non-toxic agents used, (c) easy to operate, (d) no deterioration in the physical properties of tooth materials after surgery, (e) Both pulp teeth and pulpless teeth are effective, (f) bleaching effect can appear in a short time, etc. However, the existing bleaching materials use high-concentration hydrogen peroxide as the main agent, and the...
