To determine the fluoride release from Giomer and Compomer, using different topical fluoride regimes, and to compare the amount of fluoride release from giomer with that of compomer.
Forty-eight specimens of each giomer and compomer were divided into four treatment groups, namely, control group, fluoridated dentifrice (500 ppm) once daily group, fluoridated dentifrice (500 ppm) twice daily group, fluoridated dentifrice (500 ppm) once daily + fluoridated mouthwash (225 ppm) group. Each specimen was suspended in demineralizing solution for six hours and remineralizing solution for 18 hours. Fluoride release was measured in both the demineralizing solution and remineralizing solution daily for seven days. Total daily fluoride release for each specimen was calculated by adding the amount released in the demineralizing solution to that released in remineralizing solution.
The fluoride release (ppm) was found to be more in Giomer when compared to Compomer. The fluoride released from Giomer and Compomer was significantly greater in the acidic demineralizing solution than in the neutral remineralizing solution. It was found that increasing fluoride exposure significantly increased fluoride release from the giomer and compomer. It was found that the fluoride release from the subgroups of giomer and compomer was in the following order: fluoridated dentifrice twice daily > fluoridated dentifrice once daily + fluoridated mouthwash > fluoridated dentifrice once daily > control group. It was found that the giomer showed a greater fluoride uptake than the compomer.
采用不同的局部用氟方案，测定聚硅氧烷增强型玻璃离子粘固剂（Giomer）和复合体（Compomer）的氟释放量，并比较Giomer和Compomer的氟释放量。
将Giomer和Compomer各48个样本分为四个治疗组，即对照组、每日一次使用含氟牙膏（500 ppm）组、每日两次使用含氟牙膏（500 ppm）组、每日一次使用含氟牙膏（500 ppm）+含氟漱口水（225 ppm）组。每个样本在脱矿溶液中悬浮6小时，在再矿化溶液中悬浮18小时。连续七天每天测量脱矿溶液和再矿化溶液中的氟释放量。通过将脱矿溶液中释放的量与再矿化溶液中释放的量相加，计算每个样本的每日总氟释放量。
与Compomer相比，Giomer的氟释放量（ppm）更高。Giomer和Compomer在酸性脱矿溶液中释放的氟明显多于中性再矿化溶液。研究发现，增加氟暴露量可显著增加Giomer和Compomer的氟释放量。研究发现，Giomer和Compomer各亚组的氟释放顺序如下：每日两次使用含氟牙膏＞每日一次使用含氟牙膏+含氟漱口水＞每日一次使用含氟牙膏＞对照组。研究发现，Giomer比Compomer摄取的氟更多。
