To compare single-application fluoride formulations on enamel erosion and erosion-abrasion in vitro.
Enamel specimens were pretreated with either sodium, tin, titanium, or sodium/calcium fluoride and subjected to either an erosion model or an erosion-abrasion model, after which optical profilometry was used to measure enamel step height loss.
For erosion, the titanium fluoride (P < .001) reduced enamel loss, whereas the calcium, tin, and sodium treatments showed no significant effects (P > .05). For erosion-abrasion, the titanium fluoride increased enamel loss in comparison to control (P < .001).
Titanium fluoride has differing effects on enamel loss from erosion and erosion-abrasion models.
比较单次应用氟化物制剂对牙釉质酸蚀和酸蚀磨损的作用。
对牙釉质标本进行预处理,分别使用氟化钠、氟化锡、氟化钛或氟化钠/氟化钙处理,然后进行酸蚀模型或酸蚀磨损模型实验,之后使用光学轮廓仪测量牙釉质台阶高度损失。
对于酸蚀,与对照组相比,钛氟化物(P <.001)降低了牙釉质的损耗,而钙、锡和钠处理则无明显效果(P >.05)。对于酸蚀磨损,与对照组相比,钛氟化物增加了牙釉质的损耗(P <.001)。
钛氟化物对酸蚀和酸蚀磨损模型引起的牙釉质损耗有不同的作用。
