High-fluoride dentifrice can be used to manage dental erosion; however, little is known about it effect on root dentine previously demineralized. This study evaluated the effect of high-fluoride treatment on dentin de/remineralization exposed to an erosion challenge in vitro.
Sound and demineralized dentine blocks were submitted to a 5-days-erosive challenge in soft drink (4/day during 90 s) and treated with fluoride solutions (0, 1,100, or 5,000 µg F/mL). After this, the percentage of surface hardness loss (%SHL) or recovery (%SHR) was calculated. Data were analyzed by one-way ANOVA and Tukey post hoc test with p fixed at 5%.
High-fluoride treatment was able to reduce dentine remineralization and increase mineral recovery of previously demineralized dentine compared to other treatments tested (<0.05).
High-fluoride treatment was able to increase the remineralization and reduce the demineralization of root dentine submitted to an erosive challenge in vitro, being an option for the erosion prevention/treatment. Fluorides, root caries, tooth erosion, toothpastes.
高氟牙膏可用于治疗牙釉质侵蚀；然而，此前对于其对先前已脱矿的牙本质的影响知之甚少。本研究评估了高氟处理对体外暴露于侵蚀挑战的牙本质脱矿/再矿化的影响。
将完好的和脱矿的牙本质块置于软饮料中进行为期5天的侵蚀挑战（每天4次，每次90秒），并用氟溶液（0、1、100或5000μg F/mL）进行处理。此后，计算表面硬度损失百分比（%SHL）或恢复百分比（%SHR）。数据采用单因素方差分析和Tukey事后检验进行分析，p值固定为5%。
与其他测试处理相比，高氟处理能够降低牙本质再矿化，并增加先前脱矿牙本质的矿物质恢复（<0.05）。
高氟处理能够增加体外暴露于侵蚀挑战的牙根牙本质的再矿化并减少脱矿，是预防/治疗牙釉质侵蚀的一种选择。氟化物、根龋、牙釉质侵蚀、牙膏。
