龋齿是危害人体健康的常见病。兰州地区普查学龄儿童发病率达78.9％,尤其是恒磨牙(牙合)面龋,发病迅速而损坏广泛,发病率占恒牙龋的89.4％,近年对牙(牙合)面窝沟等龋齿好发部位进行封闭以防龋是一种新的途径和方法。自74年以来,我们对光固化封闭剂进行了探讨现予报道。我们将化工部兰州涂料研究所合成的 EA—15与美国 Nuva-Seal 进行了实验室理化性能及临床观察。76年后,鉴于氟素防龋的明显效果,封闭剂中加氟是否能提高封闭剂的防龋
Caries is a common disease that endangers human health. Lanzhou area census of school-age children incidence rate of 78.9%, especially permanent molar (occlusal) surface caries, rapid onset and widespread damage, the incidence rate of 89.4% of permanent dental caries, teeth in recent years, It is a new way and method to prevent the caries by sealing the good site. Since 74 years, we have discussed the photocuring blocking agent is reported. We will Laboratory of Chemical and Lanzhou Department of Chemical Industry, EA-15 and the United States Nuva-Seal laboratory physical and chemical properties and clinical observations. 76 years later, in view of the obvious effect of fluorocarbon anti-caries, fluoride in the sealant can improve the anti-caries of the sealant
