Abstract

The invention relates to the field of dental medical treatment and in particular discloses fluorine-strengthened bioactivity mineral powder and a preparation method and an application thereof. The component system of constitution of the mineral powder is as follows: SiO-CaO-Na2O-P2O5-F. The powder comprises the following components in percentages by weight: 40-55% of SiO2, 15-30% of CaO, 15-30% of Na2O, 2-12% of P2O5 and 0.01-6% of F. According to the invention, by taking sodium monofluorophosphate as an importing components of fluorine element and controlling the mass ratio of sodium monofluorophosphate and phosphorus pentoxide added at 0.8-1.2, in a processing course, the loss of a volatile matter phosphorus pentoxide can be effectively reduced at a melting temperature of a material, so that calcium, phosphorus and fluorine in the material better meets a pre-designed proportion. By means of a shock chilling function of water, the amorphous state with more intermediate states is more easily formed, so that more crystal hydroxyapatite is formed during a reaction with water and is of higher activity. In the reaction process of the mineral powder and water, a phosphate component is further generated, thereby forming a better environment for generation of hydroxyapatite.

Description

technical field [0001] The invention relates to the field of oral medicine, in particular to a fluorine-enhanced bioactive mineral powder dental treatment. Background technique [0002] Dentin hypersensitivity (DH) is a common and frequently-occurring disease in the oral cavity. According to hydrodynamics, reducing the diameter of dentinal tubules and closing the openings of dentinal tubules to reduce and avoid fluid flow in dentin is the fundamental way to treat dentin sensitivity. The current treatment concept of anti-dentin hypersensitivity is gradually changing to early diagnosis and minimally invasive treatment, and the mineralization restoration treatment of dentinal tubules is well in line with this development trend. In long-term practice, it has been proved that apatite bioactive material and fluoride, as a traditional remineralization anti-caries substance, can also play a good role in sealing and repairing the defect of dentinal tubules. The repair process of de...
