Abstract

Objective

The purpose of the study was to compare the fluoride release in two conventional glass ionomer cements (Ionobond, Ketac Molar) and two resin-modified glass ionomer cements (Vitrebond, Fuji II LC) adapted with halloysite nanotubes preloaded with sodium fluoride at different concentrations.

Methods

In total, 96 samples were prepared and distributed into four control groups and eight experimental groups (5 % and 10 %). Totals of 10 % and 5 % of the total weight of ionomer powder needed to prepare the samples were replaced with nanotubes, preloaded at 2,000 parts per million, respectively. The experimental groups were followed for 120 days at seven time intervals. All the samples were stored at 37 °C.

Results

All the experimental groups showed significant differences compared with the control groups; likewise, differences were observed between the concentrations of 5% and 10%.

Conclusion

The experimental groups (conventional and resin-modified glass ionomer cements adapted with preloaded nanotubes) released a higher and more constant amount of fluoride compared to the control groups.

含氟预载埃洛石纳米管在传统和树脂改性玻璃离子聚合物水门汀中增强氟释放的体外研究

该研究的目的是比较两种传统玻璃离子聚合物水门汀（Ionobond、Ketac Molar）和两种树脂改性玻璃离子聚合物水门汀（Vitrebond、Fuji II LC）中氟化钠的释放情况。制备样品所需的离子聚合物粉末总重量的 10 % 和 5 % 分别被预载了 2,000 ppm 的纳米管所取代。对实验组进行了为期 120 天的跟踪观察，每次间隔 7 天。所有实验组与对照组相比都有显著差异；同样，5% 和 10% 浓度的实验组之间也有差异。
