This in vitro investigation was to evaluate the fluoride release and recharge abilities of three recently introduced dental fissure sealants (FS).
Three dental FS were assessed: Teethmate F-1 (Kuraray), Fissurit F (Voco), BeautiSealant (Shofu), and a conventional glass ionomer cement FX-II (Shofu) as a control. Eight cylindrical specimens (7 × 2 mm) of each material were made and immersed individually in 5 ml de-ionized water in plastic containers. Fluoride release of the tested materials was evaluated during the experimental period (28 days) utilising a fluoride ion-selective electrode. At the end of the test period, the specimens were soaked for 5 min in a fluoride solution (0.05 % NaF) and fluoride release was evaluated for the next 5 days. The data were statistically analysed using one-way ANOVA and Bonferroni post hoc test and the level of significance was preset at α = 0.05.
The total fluoride release over the 28-day period for each material was: FX-II (408.6 ± 45.66 μg/cm(2)) > Teethmate F-1 (89.45 ± 12.32 μg/cm(2)) > Fissurit F (68.62 ± 8.72 μg/cm(2)) > BeautiSealant (33.32 ± 4.91 μg/cm(2)), (p < 0.05). After the re-fluoridation of the specimens with 0.05 % NaF solution the cumulative fluoride re-release during the 5-day period for each material was: FX-II (99.53 ± 13.21 μg/cm(2)) > Teethmate F-1 (9.76 ± 1.62 μg/cm(2)) > BeautiSealant (5.69 ± 0.89 μg/cm(2)) > Fissurit F (4.76 ± 0.72 μg/cm(2)), (p < 0.05).
The three tested sealants exhibited different capabilities to release and uptake fluoride ions after re-fluoridation but significantly lower than the glass ionomer tested.
本体外研究旨在评估三种新推出的牙科窝沟封闭剂（FS）的氟释放和再充氟能力。
评估三种牙科窝沟封闭剂：Teethmate F-1（可乐丽）、Fissurit F（VOCO）、BeautiSealant（松风），并以传统玻璃离子水门汀FX-II（松风）作为对照。每种材料制作8个圆柱形试件（7×2毫米），分别浸入塑料容器中的5毫升去离子水中。在实验期（28天）内，使用氟离子选择性电极评估受试材料的氟释放情况。在试验期结束时，将试件在氟溶液（0.05% NaF）中浸泡5分钟，然后在接下来的5天内评估氟释放情况。数据采用单因素方差分析和Bonferroni事后检验进行统计学分析，显著性水平预设为α = 0.05。
每种材料在28天内的总氟释放量为：FX-II（408.6±45.66μg/cm²）> Teethmate F-1（89.45±12.32μg/cm²）> Fissurit F（68.62±8.72μg/cm²）> BeautiSealant（3,32±4.91μg/cm²），（p < 0.05）。用0.05% NaF溶液对试件进行再充氟后，每种材料在5天内的累积氟再释放量为：FX-II（99.53±13.21μg/cm²）> Teethmate F-1（9.76±1.62μg/cm²）> BeautiSealant（5.69±0.89μg/cm²）> Fissurit F（4.76±0.72μg/cm²），（p < 0.05）。
三种受试封闭剂在再充氟后表现出不同的氟离子释放和摄取能力，但明显低于受试的玻璃离子水门汀。
