title: Effect of experimental mouthrinses containing the combination of NaF and TiF4 on enamel erosive wear in vitro.
abstract: 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.
