Remineralization of noncavitated enamel is dependent on the bioavailability of calcium, phosphate, and hydroxyl ions in saliva. However, it is enhanced by the presence of fluoride. This study compared the remineralizing potential of three different topical fluoride agents.
Fifteen extracted premolars were selected for the study. The crown of each tooth was longitudinally sectioned buccolingually and mesiodistally using a diamond disc so as to obtain sixty specimens which were embedded in acrylic molds. The specimens were immersed in demineralizing solution for 3 days. The specimens were randomly assigned to four groups, namely Duraphat fluoride varnish, ReminPro paste, ClinPro Tooth Crème, and control group (no surface treatment). A pH cycling includes alternate demineralization and remineralization. Surface mean hardness (SMH) was recorded with 50 g load for 5 s using VHN machine at baseline, after demineralization and pH cycling. The four groups were compared for difference in SMH using one-way ANOVA followed by Tukey-Kramer test. All testing was done with alpha 0.05.
SMH recovery results for ClinPro, Duraphat, and ReminPro were 54.88%, 43.42%, and 26.86%, respectively. The difference in the percentage SMH recovery for ClinPro paste was better than Duraphat and ReminPro, and this difference was statistically significant ( < 0.05).
ClinPro tooth Crème showed the best remineralization potential among the three materials tested followed by Duraphat and ReminPro.
非龋性釉质再矿化取决于唾液中钙、磷和氢氧根离子的生物利用度。然而，氟的存在会增强再矿化作用。本研究比较了三种不同局部用氟剂的再矿化潜力。
选取15颗拔除的前磨牙进行研究。使用金刚石切割盘将每颗牙齿的牙冠沿颊舌向和近远中向纵向切割，从而获得60个标本，将其嵌入丙烯酸模具中。将标本浸泡在脱矿溶液中3天。将标本随机分为四组，即Duraphat氟漆、ReminPro糊剂、ClinPro护齿霜和对照组（未进行表面处理）。pH循环包括交替脱矿和再矿化。在基线、脱矿后和pH循环后，使用维氏硬度计在50 g载荷下持续5 s记录表面平均硬度（SMH）。使用单因素方差分析和Tukey-Kramer检验比较四组在SMH方面的差异。所有测试的α值均为0.05。
ClinPro、Duraphat和ReminPro的SMH恢复结果分别为54.88%、43.42%和26.86%。ClinPro糊剂的SMH恢复百分比差异优于Duraphat和ReminPro，且这种差异具有统计学意义（<0.05）。
在测试的三种材料中，ClinPro护齿霜显示出最佳的再矿化潜力，其次是Duraphat和ReminPro。
