Objective To study the effect of several fluorides on resistance to erosion of beverage on enamel and remineralization of etched enamel . Methods The enamel slabs were prepared from human retained primary teeth. After treated with 0.1%NaF solution, fluoride Protector and Bifluorid 12 respectively, they were immersed at intervals in beverage. The SMH were measured before and after experiments. Morphological changes of enamel surface were observed by SEM. Results The SMH of all enamel slabs descended obviously after exposed to beverage. The difference between control group and test groups was significant statistically. The variable degree etch caused by beverage were found by SEM. The SMH of etched enamel increased significantly after treated with fluoride, and the Bifluorid 12 showed the highest significant increase. Conclusion The treatment of enamel with topical fluoride can enhance the resistance of enamel to acid etch of soft drinks and the remineralization of enamel following exposed to beverage. This study recommends the Bifluorid 12 is an efficacious fluoride in remineralization of etched enamel.

目的观察三种氟化物处理后的乳牙釉质表面抵抗软饮料酸蚀及促进受损牙釉质再矿化的能力。方法应用显微硬度仪和扫描电镜,观测分别用NaF溶液、氟保护剂、双氟脱敏剂处理后再经饮料浸泡的乳牙釉质表面的显微硬度值(surfacemicrohardness,SMH)及形态的变化。结果饮料浸泡后,各组乳牙釉质的SMH均有明显降低;氟化物处理组的釉质SMH降低的程度明显低于对照组(P<0.001);氟保护剂和双氟脱敏剂组釉质SMH的降低无显著性差异,而低于单纯的NaF溶液组;扫描电镜可见釉质表面有不同程度的溶解。饮料侵蚀后又经氟化物再矿化的乳牙,釉质SMH明显增加,其中双氟脱敏剂组的釉质SMH增加最明显。结论釉质表面应用氟化物,能明显增强乳牙釉质抵抗软饮料酸蚀,并能促进受损牙釉质的再矿化修复能力,其中双氟脱敏剂的作用最明显。

Objective To investigate the effect of tea polyphenol (TP) on the mineralization behaviour of enamel in two sterile, in vitro systems. Methods In the demineralization study, sound enamel sections were pH-cycled. Treatments were 2000 mg/L TP, 200 mg/L TP, 2000 mg/L TP+100 mg/L fluoride, 100 mg/L fluoride, and deionized water. In the remineralization study, surface-softened enamel was used and pH-cycled as above. Test treatments were 2000 mg/L TP, 2000 mg/L TP+250 mg/L fluoride, 250 mg/L fluoride, and deionized...

In the remineralization study, surface-softened enamel was used and pH-cycled as above. Test treatments were 2000 mg/L TP, 2000 mg/L TP+250 mg/L fluoride, 250 mg/L fluoride, and deionized water. The acidic buffers were retained for calcium analysis. The enamel was analysed before and after pH-cycling by microhardness. Results In the demineralization study,the calcium depletion rates(CDR) were (0.43±0.05), (0.49±0.006), (0.21±0.02), (0.21±0.03) and (0.50±0.11) μg/(mm 2·h) respectively. The Knoop hardness values(KHV) percent reduction were 94.19±3.50, 96.62±0.63, 74.74 ±4.09, 77.79±3.11 and 97.32±4.03 respectively. There were no significant differences within either the TP-only groups or the fluoride groups, but the fluoride groups were significantly more efficacious than the TP-only groups (P<0.05). In the remineralization study, the KHV percent increase were -11.96±10.1, -21.32±11.3, -49.52±24.6 and -4.24±8.51 respectively. Notably more remineralization was observed in the fluoride group. There were no significant differences between the other groups (P>0.05). Conclusion The data of this in vitro study suggest that TP has no effect on de/remineralization of enamel blocks and there is no synergetic action of TP and fluoride in a sterile system. This finding supports the proposition that tea polyphenols exert an anti-caries effect via an anti-microbial mode-of-action.
