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 decolorization and whitening liniment for dental fluorosis. Background technique [0002] In the prior art, the methods for treating dental fluorosis mainly adopt bleaching, grinding and covering methods. The bleaching method uses strong acid and strong oxidant. Although strong acid can improve the color, it is easy to cause local depression, defect and tooth hypersensitivity on the tooth surface. But it was poorly calcified and chalky, like ground glass. With the prolongation of time, the phenomenon of tooth recoloration after bleaching is more obvious, as short as three or five months, and as long as two or three years. The grinding method is to remove the stained layer of 0.1-0.2 mm from the surface of the tooth body. This method is easy to damage the enamel and is difficult for patients to accept. The covering method is to use composite resin coating, veneer restoration, porcelain crown, etc., because it is difficult to achiev...
