After de- and subsequent remineralization at 0.03 and 1.0 ppm fluoride and either 0, 1, 10, 20 or 25 mM carbonate, artificial lesions in bovine enamel were demineralized again. The amount of secondary demineralization was determined after 15, 30 and 70 h of demineralization by means of quantitative microradiography. The results showed that fluoride incorporated during the remineralization period retards lesion formation during secondary demineralization. Carbonate incorporated during the remineralization period enhances secondary demineralization. An interaction between both ions was observed.
在牛牙釉质人工龋损先在0.03 ppm和1.0 ppm氟以及0、1、10、20或25 mM碳酸盐条件下脱矿然后再矿化后,再次进行脱矿。通过定量显微放射照相术在脱矿15、30和70小时后测定二次脱矿的量。结果表明,再矿化期间掺入的氟会在二次脱矿期间延缓龋损形成。再矿化期间掺入的碳酸盐会增强二次脱矿。观察到两种离子之间存在相互作用。
