Embodiment 1

[0037] Disperse 10g of sodium fluoride with an average particle size of 0.7μm and 3g of colloidal silicon dioxide in 50ml of 96% ethanol solution through an ultrasonic disperser, then add 88g of polymerized rosin, a film-forming material, and add maleated rosin, an adhesion promoter, after fully dissolving 70g, then add 3g of saccharin, 1g of watermelon essence, and continue to disperse for 3 hours until all the ingredients are completely dissolved, that is, the content of sodium fluoride is 5mg / ml, the content of film-forming material is 40%, the content of volatile solvent is 20%, and the adhesion promoter Fluoride coating material with a content of 30%. The fluoride can also be sodium monofluorophosphate, the solvent can be propanol and isopropanol, the film-forming material can be shellac, Copa resin, hydrogenated rosin, and the film-forming accelerator can be octadecyl phosphate , The suspending agent can also choose kaolin.

Embodiment 2

[0039] Disperse 10g of sodium fluoride with an average particle size of 10μm and 7g of colloidal silicon dioxide in 40ml of 96% ethanol solution through an ultrasonic disperser, then add 155g of shellac, fully dissolve, add 3g of octadecyl phosphate, and then add 2g of saccharin, 1g of strawberry essence, stirring and dispersing for 3 hours until all ingredients are completely dissolved, and then a fluoride coating film material with a sodium fluoride content of 5mg / ml, a film-forming material content of 70%, and an adhesion promoter content of 30% is obtained . Copal resin can also be used as the film-forming material, stearyl phosphate as the film-forming accelerator, and kaolin clay as the suspending agent.

Embodiment 3

[0041] Disperse 6g of sodium fluoride powder with an average particle size of 3.0μm and 1g of colloidal silicon dioxide in 130ml of 96% ethanol solution through an ultrasonic disperser, then add 60g of shellac, and after fully dissolving, add 3.1g of octadecyl phosphate , then add 2g of saccharin and 1g of strawberry essence, and continue to stir and disperse for 3 hours until all the ingredients are completely dissolved to obtain a fluoride coating with a sodium fluoride content of 5mg / ml, a solvent content of 60%, and an adhesion promoter content of 1.5%. Material. The film-forming material can also be selected from polymerized rosin or Kepa resin, the film-forming accelerator can also be selected from octadecyl phosphate, and the suspending agent can also be selected from kaolin.

Abstract

The invention relates to a hydraulic fluoride varnish material, which includes a film-forming material, a fluoride and a volatile solvent, and also includes an adhesion promoter and a suspending aid. The fluoride is superfine inorganic fluoride powder with good water solubility and its adding amount in a coating material is 1-7mg / ml; the particle size of the inorganic fluoride powder is 0.1-10.0 micrometers; and the content of the film-forming material in the coating material is 20%-90%. The hydraulic fluoride varnish material provided in the invention is a premixed single-component fluoride particle suspending magma and contains 5% of fluoride. During application, the hydraulic fluoride varnish material is directly daubed on a tooth surface, needs no blow drying, and gradually hardens into a film after encountering saliva in the oral cavity. The hardened varnish has a porous microstructure, and has good hydrophilicity, can fully release fluorine ions, and bring tooth fluorination and caries prevention functions into play.

Description

technical field [0001] The invention belongs to the technical field of dental fluoride products, and relates to a hydraulic fluoride coating film material. Background technique [0002] Dental caries is a common disease of the oral cavity. The process of caries is the process of demineralization of enamel and dentin under the action of various cariogenic factors, that is, the main inorganic component of enamel or dentin, hydroxyapatite, is dissolved by the action of acid, resulting in the demineralization of enamel minerals. lost. [0003] A large number of studies have shown that local application of fluoride ions to teeth can improve the demineralization resistance of tooth hard tissues and reduce the occurrence of caries. The anti-caries mechanism of local application of fluoride ions mainly has three aspects: (1) The released fluoride ions can diffuse into the interior of enamel or dentin through the microporous structure in the enamel or dentin structure, replacing so...
