This study aimed to evaluate and compare fluoride ion release by Cention-N (self-cure and light-cure) and conventional glass-ionomer cement (GIC) at different pH levels and time intervals.
For fluoride release assessment, 240 samples (10 mm diameter, 2 mm height) of Cention-N and conventional glass-ionomer cement were created using rubber rings. Samples were stored in deionized water, and the cumulative fluoride ion release and change in pH were assessed using a spectrophotometer and pH meter, respectively, at the end of 7 days, 14 days, and 21 days. The obtained data were subjected to statistical analysis.
All three samples exhibited very high fluoride release in an acidic medium compared to the neutral medium. Although GIC demonstrated superior fluoride release, Cention-N displayed adequate fluoride release over a longer duration.
Within the limitations of this study, it can be concluded that both Glass ionomer cement and Cention-N showed an initial fluoride burst.
本研究旨在评估和比较Cention-N（自固化和光固化）与传统玻璃离子水门汀（GIC）在不同pH水平和时间间隔下的氟离子释放情况。
为评估氟释放情况，使用橡胶圈制作了240个Cention-N和传统玻璃离子水门汀的样本（直径10毫米，高2毫米）。样本储存在去离子水中，分别在7天、14天和21天结束时使用分光光度计和pH计评估累积氟离子释放量和pH值变化。对获得的数据进行统计分析。
与中性介质相比，所有三个样本在酸性介质中均表现出非常高的氟释放。尽管GIC显示出更好的氟释放，但Cention-N在更长时间内显示出足够的氟释放。
在本研究的局限性内，可以得出结论，玻璃离子水门汀和Cention-N均表现出初始氟离子突释。
