OBJECTIVE
This study analysed the anti-erosive effect of experimental solutions containing TiF4 and NaF.
METHODS
Bovine enamel samples (n=15) were treated with: (1) commercial solution with SnCl2/NaF (Erosion Protection(®)); (2) experimental solution with 0.0815% TiF4; (3) 0.105% NaF; (4) 0.042% NaF + 0.049% TiF4; (5) 0.063% NaF + 0.036% TiF4 or (6) control. The samples were submitted to pH cycles and daily fluoride applications for seven days. The enamel wear was measured using a contact profilometer and analysed by ANOVA (p < 0.05).
RESULTS
The best anti-erosive effect was found for experimental solution with 0.0815% TiF4 (99% reduction in enamel wear), followed by SnCl2/NaF (78%) and 0.049% TiF4 + 0.042% NaF solution (41%).
CONCLUSIONS
The experimental solution containing a specific combination of TiF4 + NaF has the ability to partially reduce enamel erosion.
目的
本研究分析了含四氟化钛（TiF4）和氟化钠（NaF）的实验溶液的抗侵蚀作用。
方法
对15个牛牙釉质样本进行如下处理：（1）含氯化亚锡/氟化钠的商业溶液（防侵蚀液（®））；（2）含0.0815%四氟化钛的实验溶液；（3）0.105%氟化钠；（4）0.042%氟化钠 + 0.049%四氟化钛；（5）0.063%氟化钠 + 0.036%四氟化钛；或（6）对照。样本进行pH循环处理，并每日应用氟化物，持续7天。使用接触式轮廓仪测量牙釉质磨损情况，并通过方差分析进行分析（p < 0.05）。
结果
含0.0815%四氟化钛的实验溶液显示出最佳抗侵蚀效果（牙釉质磨损减少99%），其次是氯化亚锡/氟化钠（78%）和0.049%四氟化钛 + 0.042%氟化钠溶液（41%）。
结论
含特定比例四氟化钛 + 氟化钠的实验溶液有部分减少牙釉质侵蚀的能力。
