RESUMO:

Objective: To evaluate, in vitro, the erosive potential of energy drinks modified by different variations and concentrations of calcium on dental enamel. Methodology: This is an in vitro study in which 60 specimens of healthy human dental enamel were used. Initially, all specimens had their surface roughness (Ra and Rz1max) and microhardness measured using a rugosimeter and a Vickers microhardness tester, respectively. Subsequently, they were divided into three groups and 12 subgroups (five per subgroup) to be exposed to the tested beverages, which were as follows: Experimental group (G1 to G9 – Red Bull® traditional energy drink modified with concentrations of 0.71, 1.43, and 2.15 grams of the calcium/phosphorus/potassium complex; 0.83, 1.66, and 2.50 grams of dicalcium malate; and 1.26, 2.53, and 3.80 grams of calcium citrate malate, respectively); negative control group (G10 – Traditional Red Bull® energy drink and G11 – Deionized water); and positive control group (G12 – Low-Calorie Life Mix Orange Juice® supplemented with calcium). The pH of all beverages was measured using a calibrated pH meter with a pH electrode. After preparing all the beverages, the specimens were exposed to them for two minutes. Finally, their surface roughness (Ra and Rz1max) and microhardness were reevaluated. For statistical analysis, the Kruskal-Wallis, Mann-Whitney, and Wilcoxon tests were applied, adopting a significance level of 5%. Results: Regarding the pH behavior of the beverages, modifications to the energy drink with concentrations of the calcium/phosphorus/potassium complex increased its pH concurrently with the substance concentration. As for the analysis of specimen roughness, the experimental group showed a significant difference (p < 0.004) compared to subgroups G10, G11, and G12 for the Ra and Rz1max parameters. In the evaluation of specimen microhardness, significant differences (p < 0.004) were observed between subgroups: G3-G10, G6-G10, and G10-G11. All specimens exposed to the beverages in the experimental group had a lower percentage of enamel surface hardness loss compared to those exposed to subgroups G10 and G12. Conclusion: The calcium variations added to the energy drink demonstrated effectiveness in reducing the erosive potential of this type of beverage at all tested concentrations on dental enamel, with better performance observed for the calcium/phosphorus/potassium complex.
