龋病是最常见疾病之一,对我国劳动人民健康影响大而广泛,据不完全统计,我国人民患龋病率在50%左右。如何有效地防治龋病,是直接关系到贯彻毛主席革命卫生路线的重大问题。目前,临床上治疗龋病所应用的充填材料,如硅粘固粉、丙烯酸酯类自凝塑胶都存在某些严重的缺陷如硬度小,容易变形等;银汞合金虽然较好,但也存在着汞害、价贵、来源不易、操作较繁等问题。因此,急需研制一种新型的充填材料,来更好地为广大工农兵服务。
Caries is one of the most common diseases, affecting the health of our working people widely and widely. According to incomplete statistics, the caries prevalence of our people is about 50%. How to effectively prevent dental caries is a major issue directly related to the implementation of Chairman Mao's revolutionary health line. Currently, there are some serious defects such as hardness and easy deformation of filling materials used in the treatment of dental caries, such as silicon cement and acrylate self-setting plastic. Silver amalgam is better though it exists With mercury damage, expensive, not easy to source, complex operation and other issues. Therefore, the urgent need to develop a new type of filling material to better serve the workers, peasants and soldiers.
