Effect of enamel after immersion in carbonated and rehydrating beverages

Introduction The daily consumption of soft and sports drinks has a certain impact on dental tissues, causing a decrease in the pH of the oral cavity and demineralization of enamel and dentin. Objective. The objective was to evaluate the effect of carbonated and isotonic rehydrating beverages on dentin enamel microhardness in extracted permanent teeth. Methodology. Longitudinal, experimental, prospective, invitro study carried out at the Micro and Nanotechnology Research Center of the U.V. Contribution. A significant decrease in the enamel microhardness values was found in all groups when subjected to the acidic action of the beverages, and the loss of surface microhardness was evidenced. It was demonstrated that all the industrialized beverages used produced a decrease in the microhardness of the dental enamel, but not in the same intensity, with Coca-Cola having a greater decrease followed by Sidral Mundet, then Powerade and finally Gatorade. Discussion The results agree with Sandra Vargas Casana, who found that Coca-Cola had the greatest decrease in microhardness.
