The ability of different formulations of artificial saliva to protect dentin from erosive wear

Objective: Evaluate the protective effect of artificial saliva formulations associated or not with mucin on dentin. Materials and Methods: Bovine dentin specimens were randomly allocated to 10 groups (n = 20) according tested presence absence mucin: Amaechi et al. (1998); Klimek (1982); Vieira (2005) Eisenburger (2001) deionized water (control). Samples submitted an erosive cycle consisting two immersions 120 min in saliva, followed by 1 hydrochloric acid solution, new storage for min. Surface loss ( um) was measured before after cycle. Data analyzed using 2-way ANOVA Tukey’s test (p < 0.05). Results: A significant difference observed formulation but mucin. The provided highest surface Eisenburger’s lowest. testing Amaechi, Klimek, did present differences. Conclusion: provides a higher against erosion. increase erosion-preventive formulations.
