ABSTRACT
OBJECTIVE:
This in vitro study assessed the anti-erosive effect of experimental mouthrinses containing TiF4 and NaF on dentin erosive loss. MATERIAL ANDMETHODS:
Bovine dentin specimens were randomly allocated into the groups (n=15) (1) SnCl2/NaF/AmF (Erosion Protection/GABA, pH 4.5, positive control); (2) experimental solution with 0.0815% TiF4(pH 2.5); (3) 0.105% NaF (pH 4.5); 4) 0.042% NaF+0.049% TiF4 (pH 4.4); (5) 0.063% NaF+0.036% TiF4 (pH 4.5); (6) no treatment (negative control). Each specimen was cyclically demineralized (Sprite Zero, pH 2.6, 4x90 s/day) and exposed to artificial saliva between the erosive challenges for 7 days. The treatment with the fluoride solutions was done 2x60 s/day, immediately after the first and the last erosive challenges of the day. Dentin erosive loss was measured by profilometry (µm). The data were analyzed using Kruskal Wallis/Dunn tests (p<0.05).RESULTS:
Mouthrinses containing TiF4or Sn/F were able to show some protective effect against dentin erosive loss compared to negative control. The best anti-erosive effect was found for experimental solution containing 0.0815% TiF4 (100% reduction in dentin loss), followed by 0.042% NaF+0.049% TiF4 (58.3%), SnCl2/NaF/AmF (52%) and 0.063% NaF+0.036% TiF4 (40%). NaF solution (13.3%) did not significantly differ from control.CONCLUSION:
The daily application of experimental mouthrinse containing TiF4 and NaF has the ability to reduce dentin erosion, as well as Erosion Protection and TiF4 alone.
