Incorporating Arginine in fancy water beverages lowers erosive tooth wear potential of these beverages: Study
Researchers have reported that the addition of arginine (Arg) in flavored fancy waters significantly lowers their potential to cause erosive tooth wear. Erosive tooth wear is a progressive loss of enamel caused by acidic beverages, commonly seen among young people. A recent study was conducted by Mohammed N. and colleagues published in the Journal of Dentistry.
With the increased popularity of flavored sparkling and carbonated beverages, erosive wear is an important issue. The oral health benefits of L-arginine have been reported in various studies. In this study, the efficacy of five commercially available fancy waters containing L-arginine was tested in reducing tooth wear over a controlled period of 72 hours.
The five commercial fancy waters, Oasis Lemon, Oasis Lemon Mint, Perrier Lemon, Perrier Grapefruit, and Pellegrino Lemon, were enriched with 2% L-arginine (w/v). Deionized water was used as a negative control. Key parameters, such as pH, buffer capacity, and fluoride (F−) concentrations, were measured to determine the impact of arginine addition.
To prepare, specimens were subjected to baseline volumetric analysis using micro-CT imaging. The specimens were then placed in the beverages for 72 hours at 37°C, with solutions changed every 24 hours. Post-exposure, 3D volumetric assessments and structural reconstructions were conducted to quantify and visualize enamel wear.
