普洱茶水浸液抑制牙釉质脱矿作用初探
Preliminary study of Pu'er tea on inhibition of enamel demineralization
摘要
Abstract
Objective To explore the inhibitory effect of different solvent extracts of Pu'er tea (raw tea and ripe tea) on enamel demineralization. Methods Phosphorus ion concentration of lactate buffer was tested and phosphorus dissolution rate in free teeth was calculated before and after treatment with different solvent extracts of Pu'er tea (raw tea and ripe tea) and the effect of different solvent extracts of Pu'er tea in inhibiting enamel demineralization was evaluated by setting 20 mg/ml NaF group as the positive control group and deionized water group as the negative control group. Results Compared with the blank group of water, the phosphorus dissolution rates were significantly different in the different solvent extracts of Pu'er tea (raw tea and ripe tea), NaF group and deionized water group (P < 0.05) and there were also significant differences among the different solvent extracts of Pu'er tea (raw tea and ripe tea) (P < 0.05). At the same concentration, the raw tea had stronger effect than the ripe tea with significant difference (P < 0.05). Conclusions Different solvent extracts of Pu'er tea (raw tea and ripe tea) can inhibit enamel demineralization. The higher the concentration of Pu'er tea extracts, the stronger the effect.关键词
