Identification of tested groups.

ObjectivesTo evaluate the erosive potential of an energy drink modified with different calcium formulations and concentrations on dental enamel.MethodsThis in vitro study used sixty dental enamel specimens, divided into 12 groups: traditional Red Bull® energy drink modified with three concentrations each of calcium/phosphorus/potassium complex (0.71, 1.43, and 2.15g), dicalcium malate (0.83, 1.66, and 2.50g), and calcium citrate malate (1.26, 2.53, and 3.80g); unmodified traditional Red Bull® energy drink; deionized water; and commercially available calcium-supplemented Life Mix Baixa Caloria® orange juice. The pH of all drinks was measured using a pHmeter. Specimens were exposed to the drinks for two minutes. Surface roughness and microhardness were assessed before and after exposure using a contact profilometer and a Vickers microhardness tester, respectively.ResultsThe addition of calcium/phosphorus/potassium complex increased the energy drink’s pH proportionally to the concentration added. Specimens exposed to modified drinks showed reduced roughness (p ConclusionThe addition of calcium formulations to the energy drink effectively reduced its erosive potential at all concentrations, with the calcium/phosphorus/potassium complex demonstrating the greatest protective effect.
