High-efficiency tooth bleaching gel for dental treatment room

Abstract

The invention relates to a high-efficiency tooth bleaching gel for a dental treatment room. The high-efficiency tooth bleaching gel comprises a first gel containing at least one peroxide and a second gel containing an activator gel, wherein the activator gel contains at least one organic amine; a weight ratio of the first gel to the second gel is 4:1-10:1; the organic amine is hydroxyl-alkylamine which has the general formula of HOR-NH-ROmH; and in the formula, m is 0 or 1, and R refers to alkyl and has the general formula of CnH2n, wherein n is 1, 2, 3, 4, 5, 6 or 7. The high-efficiency tooth bleaching gel has a high-efficiency and stable bleaching treatment effect on discolored teeth required to be bleached, and also has antiallergic and remineralizative effects on the teeth. The bleaching treatment effect is obviously enhanced, and the excellent bleaching effect percentage is 78.75 percent; meanwhile, tooth hypersensitivity is reduced, and the sensitivity rate is only 22.5 percent.

Description

technical field [0001] The invention belongs to fine chemical industry, and relates to a tooth bleaching product for a dental office. More specifically, the invention particularly relates to a powerful two-component tooth bleaching gel for a dental office. Background technique [0002] In daily life, a person's teeth can become discolored or darkened due to prolonged and repeated exposure to substances such as tea, coffee, cola, red wine, cigarettes, colored foods, or certain drugs (such as tetracycline) and excessive fluoride. In order to solve this problem, cosmetic treatment of teeth is usually required. Teeth bleaching can be divided into two types: dental clinic and home use according to the place of use. The home-based tooth bleaching method is cumbersome to operate, slow to take effect, lasts for a long time, and is more likely to demineralize and sensitize the teeth, so it is not easily accepted by patients. The method of tooth bleaching in the dental office usuall...

Problems solved by technology

[0003] However, the tooth bleaching materials used in dental clinics in the past usually consist of 35% by weight of hydrogen peroxide gel and an appropriate amount of transition metal salts as a catalyst to form a two-component tooth bleaching system. When the products are mixed and extruded, they are applied to the teeth that need to be bleached. When the two components are mixed, the hydrogen peroxide-free catalyst dilutes the concentration of hydrogen peroxide, and its actual hydrogen peroxide content is only 28%. In order to prolong the shelf life of hydrogen peroxide gel as much as possible, the shelf life often needs to be one year or even longer. Hydrogen peroxide gel is designed as an acidic system with a pH value of 3-5 or even lower. Hydrogen oxide will also decompose in a small amount and produce hydrogen ions, and the acidity will be enhanced, so the pH value will be lower in actual use. The teeth exposed to the acidic peroxide environment will cause the dissolution and loss of calcium, resulting in tooth demineralization. become sensitive and more likely to re-stain, often as bleached teeth quickly turn yellow or darker in a short period of time
