This 30-day study, compared the amounts and patterns of fluoride release from 5 commercially available fluoride-containing pit and fissure sealants: FluroShield, Helioseal-F, Ultraseal XT, Baritone L3, and Teethmate-F; Delton without fluoride, was used as control. Disc-shaped samples of each sealant were immersed in distilled water and the fluoride release was measured periodically until day 30. All the fluoridated sealants tested released measurable fluoride throughout the test period in a similar pattern: the greatest amount of fluoride was released in the first 24 hours after mixing, fell sharply on the second day and decreased slowly for the last days. On day one, Baritone L3 released significantly more fluoride than all other materials. Teethmate-F released the highest amount of fluoride during all the other time intervals from day 2, until day 30.
这项为期30天的研究比较了5种市售含氟窝沟封闭剂（FluroShield、Helioseal-F、Ultraseal XT、Baritone L3和Teethmate-F）的氟释放量和释放模式；不含氟的Delton用作对照。将每种封闭剂的圆盘形样本浸入蒸馏水中，定期测量氟释放量，直至第30天。所有测试的含氟封闭剂在整个测试期间都以类似模式释放出可测量的氟：混合后最初24小时内释放的氟量最大，第二天急剧下降，在最后几天缓慢减少。在第1天，Baritone L3释放的氟比所有其他材料都多得多。从第2天到第30天的所有其他时间段内，Teethmate-F释放的氟量最高。
