Decoloring agent for dental fluorosis

Abstract

A liniment for removing the fluorine spots from tooth includes two products. The liniment A is prepared from 7 Chinese-medicinal materials including dahurian angelica root, as arum herb, Chuan-xiong rhizome, fresh tangerine peel, etc through proportional mixing, immersing in 2-8 % solution of hydrochloric acid and filtering. The liniment B is prepared from pumice through grinding, immersing in solution of sodium fluoride, and filtering. Its advantages are high speed, no damage to tooth enamel, and 100% of cure rate.

Description

Technical field [0001] The invention is a decolorizing and whitening liniment for dental fluorosis. Background technique [0002] In the prior art, the methods for treating dental fluorosis mainly adopt the bleaching method, the abrading method and the covering method. The bleaching method uses strong acids and strong oxidants. Although strong acids can improve the color, local dents, defects and tooth hypersensitivity are likely to occur. The strong oxidants form demineralization under the enamel surface, the surface refractive index changes, and the tooth color may become white. But it is poorly calcified and chalky, like ground glass. As time goes by, the color of teeth after bleaching is more obvious, ranging from three to five months as long as two to three years. The abrasion method is to remove the stained layer from the surface of the tooth body by 0.1 to 0.2mm. This method is easy to damage the enamel and is difficult for patients to accept. The covering method is to use...
