摘要:
目的    检测4种不同含氟窝沟封闭剂的氟离子释放和回收能力。    方法      采用4种不同的含氟窝沟封闭剂,包括Fuji VⅡ、FujiⅡLC、Fissurit F 以及Teethmate F-1。将各种材料制备成圆盘状样本,储存在含有5 ml去离子水的聚乙烯试管中,21 d后,用1.23%酸性磷酸氟(APF)凝胶处理每个样本,用氟离子选择性电极检测1~7、14、21、22、28、35 d和42 d的氟释放量。    结果      玻璃离子封闭剂Fuji VⅡ氟离子释放量最高;树脂加强型玻璃离子封闭剂FujiⅡLC氟离子回收能力最强;Fissurit F氟离子回收能力最差。在整个检测时间段内,玻璃离子类封闭剂比其他封闭剂有更高的氟离子释放(P<0.05);4种封闭剂在APF凝胶处理后氟离子释放均有显著性增高(P<0.05)。    结论      在6周的短期研究中,玻璃离子为基础的封闭剂Fuji VⅡ和FujiⅡLC与其他封闭剂比较显示了较高的氟离子释放及回收能力。
Abstract:
Objective      To determine the fluoride release and recharge of 4 different types of fluoride-containing pit and fissure sealants in vitro.     Methods      Fuji VⅡ, FujiⅡLC, Fissurit F and Teethmate F-1 were used to investigate fluoride release and recharge. Disk-shaped specimens were prepared from each material. Specimens were stored in a polyethylene test tube containing 5.0 ml ultrapure water. On day 21, specimens were exposed to 1.23% APF gel. Fluoride release was measured using a fluoride-specific ion electrode at days 1 to 7, 14, 21, 22, 28, 35 and 42 respectively.     Results      The glass-ionomer sealants Fuji VⅡ had the highest fluoride release, and resin-modified glass-ionomer cement FujiⅡLC had the highest fluoride recharge, but Fissurit F had the lowest recharge. The glass-ionomer based sealants had significantly higher fluoride release than the other materials at all times tested (P<0.05). Fluoride release of all materials tested was increased following exposure to 1.23% APF gel (P<0.05).     Conclusion      In this short-term study of 6 weeks, glass ionomer-based sealants Fuji VⅡ and FujiⅡLC have higher initial fluoride release as well as higher fluoride recharge than other sealants.
