OBJECTIVE(S): The aim of the study was to examine the potential of arginine (Arg)-enriched fancy waters in preventing erosive tooth wear. METHODS: L-arginine (2 % w/v.) was added to five commercial fancy waters: Oasis-Lemon, Oasis-Lemon Mint, Perrier-Lemon, Perrier-Grapefruit, Pellegrino-Lemon
and deionized water served as a negative control. The pH, buffer capacity of added Arg, and F RESULTS: The pH and F CONCLUSION: Incorporating Arg in fancy waters reduces the potential of erosive tooth wear associated with these beverages. CLINICAL SIGNIFICANCE: Consuming fancy water beverages (flavoured sparkling/carbonated) can lead to erosive tooth wear in young people. Incorporating Arg in fancy water beverages can prevent the erosive wear potential of these beverages while alleviating the burden of oral care on individuals at risk to erosive wear.
