Abstract

BACKGROUND

We aimed to determine the fluoride release and fluoride-recharging ability of a sealant containing surface pre-reacted glass (S-PRG) ionomer filler particles (BeautiSealant) with a fluoride-releasing resin sealant (Helioseal F), and a glass-ionomer sealant (Fuji VII).

METHODOLOGY

Forty-eight disc-shaped specimens of each material were immersed in deionized water to determine the fluoride release utilizing a fluoride ion-selective electrode. After 21 days, 8 specimens were soaked in 0.22% Sodium Fluoride solution for 2 min; 8 specimens were coated with 1.23% Acidulated Phosphate Fluoride (APF) gel for 4 min, and the fluoride-recharging ability was evaluated for 40 days. Data were analyzed using one way-ANOVA and Bonferroni post hoc tests.

RESULTS

Total fluoride release over the 21-day period was: Fuji VII > BeautiSealant > Helioseal F, (P = 0.000). After refluoridation of the specimens with 0.22% Sodium Fluoride solution, the cumulative fluoride release during the 40-day period for each material was: BeautiSealant > Fuji VII > Helioseal (P = 0.000). After exposure to 1.23% APF gel, the cumulative fluoride release during the 40-day period for each material was: BeautiSealant > Fuji VII > Helioseal F (P = 0.000).

CONCLUSION

Glass ionomer-based sealants (Fuji VII) exhibited higher initial fluoride release whilst the surface pre-reacted glass-ionomer filler containing sealant (BeautiSealant) demonstrated superior fluoride recharging properties.

摘要

背景

我们旨在测定含表面预反应玻璃（S-PRG）离聚物填料颗粒的窝沟封闭剂（BeautiSealant）、含氟释放树脂的窝沟封闭剂（Helioseal F）以及玻璃离子窝沟封闭剂（Fuji VII）的氟释放量和氟再充注能力。

方法

每种材料制备48个圆盘形样本，将其浸入去离子水中，使用氟离子选择性电极测定氟释放量。21天后，8个样本浸泡于0.22%的氟化钠溶液中2分钟；8个样本涂覆1.23%的酸性磷酸氟（APF）凝胶4分钟，评估40天内的氟再充注能力。数据采用单因素方差分析和Bonferroni事后检验进行分析。

结果

21天内的总氟释放量为：Fuji VII > BeautiSealant > Helioseal F，（P = 0.000）。用0.22%的氟化钠溶液对样本进行再氟化后，每种材料在40天内的累积氟释放量为：BeautiSealant > Fuji VII > Helioseal（P = 0.000）。暴露于1.23%的APF凝胶后，每种材料在40天内的累积氟释放量为：BeautiSealant > Fuji VII > Helioseal F（P = 0.000）。
