摘要
目的:观察镧奶对牙齿的再矿化、抗酸脱矿作用。方法:利用显微硬度仪测定镧奶和镧水对早期人工龋的再矿化作用。利用偏光显微镜观察镧奶和镧水的抗酸脱矿作用。结果:镧奶和镧水均有再矿化、抗酸脱矿的作用。结论:体外实验表明含镧4mg.L-1的镧奶防龋作用强于镧水。
Objective： To observe the effects of remineralition and anti-demineralization of lanthanum milk in vitro experiments. Methods： A set of deminerfalized bovine teeth specimens were measured for microhardness to assess the degree of remineralization, and two other sets of bovine teeth specimens were examined with polarizing microscope to assess the antidemineralization. Results： Lanthanum milk and Lanthanum water had significant effects of remineralization and antidemineralization. Conclusion： 4mg·L^-1 lanthanum milk shows better effect of caries prevention than lanthanum water.
