测定了Miracle Mix（MM）、Ketac-Silver（KS）和Ketac-Bond（KB）三种玻璃离子产品制成的圆盘在人工唾液中3周的氟释放速率。光盘要么没有上清漆，要么上清漆，要么上清漆并完成。释放速率与产品的氟浓度不成正比，其顺序为：MM > KB > KS。无论使用何种产品或治疗，发生率均随时间急剧下降。根据产品的不同，对光盘上清漆会导致61-76%的减少。完成清漆光盘产生了显着增加的氟释放从MM，但没有影响从KS或KB的释放。在MM的一项单独研究中，确定氟化物的释放速率与用于制备圆盘的粉末：液体比成反比。
The release rates of fluoride from discs made from three glass ionomer products, Miracle Mix (MM), Ketac-Silver (KS) and Ketac-Bond (KB), into artificial saliva for 3 weeks were determined. The discs were either not varnished, varnished or varnished and finished. The release rates were not proportional to the fluoride concentrations of the products and were ordered: MM > KB > KS. The rates declined sharply as a function of time regardless of the product or treatment. Varnishing the discs caused a reduction of 61-76% depending on the product. Finishing the varnished discs produced a significant increase in the fluoride release from MM but had no effect on the release from KS or KB. In a separate study with MM, it was determined that the release rate of fluoride was inversely proportional to the powder: liquid ratio used to prepare the discs.
