该市第九人民医院口腔科研究所在龋病预防方法研究中,以绿茶提取物茶多酚为主要成分,用聚丙烯酯为基质,研制成功了绿茶多酚防龋涂膜,并于不久前通过了专家鉴定。 在多种防龋方法中,国外使用最多的是氟化物涂膜。由于氟化物与高分子材料的相容性较差,涂膜中氟化物释放快,使其在一定程度上降低了作用效果;又因涂膜中含氟浓度较高,存在氟化物毒性问题。该院课题组在研究
Ninth People's Hospital of the city's Institute of Stomatology in the study of caries prevention methods to green tea extract tea polyphenols as the main component, with polypropylene ester as the substrate, the successful development of green tea polyphenols anti-caries coating, and soon Before passed the expert appraisal. In a variety of anti-caries methods, the most widely used fluoride coating. Due to the poor compatibility of fluoride and polymer materials, the release of fluoride in the coating is quick, which reduces the effect of the coating to a certain extent. However, due to the high concentration of fluorine in the coating, fluoride toxicity exists. The hospital research group in the study
