Abstract: | ObjectiveThis study analysed the anti-erosive effect of experimental solutions containing TiF4 and NaF.MethodsBovine 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).ResultsThe 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%).ConclusionsThe experimental solution containing a specific combination of TiF4 + NaF has the ability to partially reduce enamel erosion. |
