牙结石可以导致牙龈炎或牙周病的进一步发展,已有文献报道由于茶中含有鞣质(多酚类)和大量的氟及茶的杀菌作用,所以饮茶可以有效地减少人或大鼠龋齿和牙周病的发病率。因此,作者试图通过条和其它抗牙结石物质的比较研究,以期评价茶的抗牙结石作用。本实验探讨了三种茶(红茶、乌龙茶、绿茶)浸出物及甘草溶出物对磷酸钙沉淀物的形成及钙螯合能力的影响。 材料与方法:①将上述3种袋泡茶浸 Dental calculus can lead to the further development of gingivitis or periodontal disease. It has been reported in the literature that drinking tea can effectively reduce the human or rat due to the bactericidal effect of tea containing tannins (polyphenols) and a large amount of fluoride and tea. The incidence of dental caries and periodontal disease. Therefore, the authors attempted to evaluate the anti-calculus effect of tea by comparing bar and other anti-calculus substances. This experiment explored the effects of three tea (black tea, oolong tea, and green tea) leachates and licorice leachate on the formation of calcium phosphate precipitates and calcium chelation. Materials and Methods: 1 The above 3 kinds of teabag dip
