Forty children aged 8-10 years participated in this study. Half (n =20) of them used orthodontic appliances which contained fluoride-releasing devices embedded in the lingual surface of the appliance and the other half used orthodontic appliances prepared from a fluoride-releasing acrylic polymer. Prior to the adjustment of appliances and after 1, 7, 14, 21 and 30 days salivary and urinary samples were collected and the fluoride concentrations were determined. The mean fluoride release was highest during the first week. However, the values decreased considerably after that and the curves for the two groups became parallel. The results indicate that fluoride-releasing removable appliances could be useful for a prolonged release of low concentrations of fluoride without any systemic effect.
40名8至10岁的儿童参与了这项研究。其中一半（n = 20）使用了正畸矫治器，这些矫治器在其舌面嵌入了含氟释放装置，另一半使用了由含氟丙烯酸聚合物制备的正畸矫治器。在矫治器调整前以及调整后1天、7天、14天、21天和30天，收集唾液和尿液样本并测定氟浓度。氟的平均释放量在第一周最高。然而，此后该值大幅下降，两组的曲线变得平行。结果表明，含氟释放的可摘矫治器可用于长时间释放低浓度的氟且无任何全身效应。
