The objective of this research was to establish the erosive effect of three industrialized beverages on dental enamel. This was an experimental in vitro study conducted at the Sputtering Laboratory of the Faculty of Sciences at the National University of Engineering. The sample consisted of 32 completely healthy teeth, without restorations and extracted less than a month prior, which were exposed to the action of four types of beverages (carbonated, rehydrating, energy drinks, and physiological serum) for 10 minutes at a temperature of 37ºC. The teeth were then rinsed and stored in physiological serum. This procedure was repeated once daily for 5 days. Results: The carbonated beverage caused a 0.07% reduction in baseline microhardness by the third day and 12% by the fifth day. The rehydrating beverage caused a 20.07% reduction in baseline microhardness by the third day and 38.66% by the fifth day (p=0.012). The energy drink caused a 32.17% reduction in baseline microhardness by the third day (p=0.004) and 40.91% by the fifth day (p<0.001). The physiological serum caused a 9.15% reduction in baseline microhardness by the first day. Conclusion: There is an erosive effect from all three industrialized beverages on dental enamel. However, the beverage that produced the greatest enamel hardness loss in the shortest amount of time was the energy drink.
