Abstrakt: Objectives: To evaluate the effects of dentifrices containing sodium fluoride (NaF) combined with NovaMin (Sensodyne Repair & Protect-SRP), NaF combined with stannous fluoride (SnF 2 , Oral-B Pro-Gengiva-OBP), and amine fluoride (AmF, Colgate Elmex-ELM) on enamel subjected to simulated erosive cycling.
Materials and Methods: Bovine enamel-dentin discs (n = 10/group) were subjected to erosive cycling with orange juice (pH = 3.29, 5 min, 3x/day), artificial saliva (SA-2 h, 3x/day and overnight) and treated with dentifrice (2 min, 2x/day) or without treatment (CONT). Surface microhardness (SMH) was evaluated at baseline (T 0 ), on the first (T 1 ) and fifth (T 5 ) days. SMH loss (%SHL) was calculated. Surface roughness (Ra, μm) was determined at T 0 and T 5 . Morphology and mineral content were evaluated under scanning electron microscopy and energy-dispersive x-ray spectroscopy. Data were analyzed using ANOVA/Tukey or Bonferroni (α = 5%).
Results: No differences in %SHL were detected among groups at T 1 . At T 5 , OBP promoted %SHL, Ra, and ΔRa significantly lower than all the other groups (p < 0.05). All groups exhibited morphological changes in topography and similar Ca/P means before and after treatments.
Conclusions: Dentifrice containing SnF 2 minimized the negative effects on the SMH and Ra caused by exposure to orange juice after 5 days of simulated cycling.
Clinical Relevance: Patients who are more exposed to risk factors for dental erosion could benefit from the use of dentifrice containing SnF 2 .
