双氟保健牙膏双氟保健牙膏由辽宁省卫生防疫站儿少卫生科研制,哈尔滨日用化学厂加工。已在辽宁省部分中小学中试用二年,效果很理想。此种牙膏的药物配方和磨料选型在国内处领先地位,与美国Oral公司生产的双氟牙膏不相上下。双氟保健牙膏中两种氟化物为单氟磷酸钠(Na_2PO_4F)、氟化钠(NaF)。单氟磷酸钠县有高渗透性,牢固地吸附于牙齿表层,与牙齿表层组织磷灰石结合形成更为稳定、更为坚硬的物质;氟磷灰石,提高牙齿的抗酸力、降低釉质的溶解度,防止牙齿脱钙。氟化钠主要作用于牙齿深层;牙本质,参与早期龋损破坏后的修复,再矿化。阻止龋损的扩延和进展。两种药物联合应
Dual fluoride toothpaste fluoride fluoride toothpaste by the Health and Epidemic Prevention Station of Liaoning Province less health research, Harbin Daily Chemical Factory processing. Has been in some primary and secondary schools in Liaoning Province for two years, the effect is very satisfactory. This toothpaste drug formulations and abrasive selection at the leading position in the country, with the United States produced dual-tooth Oral toothpaste comparable. The two fluorides in the dual fluoride toothpaste are sodium monofluorophosphate (Na 2 PO 4 F) and sodium fluoride (NaF). Sodium monofluorophosphate has high permeability and firmly adheres to the tooth surface and binds to the apical surface tissue apatite to form a more stable and harder substance. Fluoroapatite improves the acid resistance of the teeth and reduces enamel The solubility of teeth to prevent decalcification. Sodium fluoride mainly acts on the deep teeth; dentin, involved in the repair of early carious damage, remineralization. Prevent the spread and progression of carious lesions. The two drugs should be combined
