The purpose of this study was to gain a deeper understanding of factors affecting fluoride-ion release from a newly developed fluoride releasing resin (F-resin) under various conditions. Both higher temperature and longer immersion times resulted in a greater amount of fluoride ion released from this material, whereas thermal cycling did not accelerate the fluoride release. It was also found that the amount of released fluoride ion increased with increase in pH. The experiments performed also demonstrated that the fluoride release rate was reduced by polishing or heating the test disc of F-resin. Although the amount of released fluoride ion varied with each experimental conditions employed, a fluoride ion release was always observed under all experimental conditions.
本研究的目的是更深入地了解在各种条件下影响一种新开发的释氟树脂（F-树脂）氟离子释放的因素。较高的温度和较长的浸泡时间都会导致该材料释放出更多的氟离子，而热循环并不会加速氟的释放。还发现释放的氟离子量随pH值的升高而增加。所进行的实验还表明，通过对F-树脂测试盘进行抛光或加热会降低氟的释放速率。尽管在每种采用的实验条件下释放的氟离子量有所不同，但在所有实验条件下均始终观察到氟离子的释放。
