The occurrence and progress of enamel demineralization may be reduced in the presence of its reaction products, such as calcium. Therefore, in this study the hypothesis that lower erosive potential may be expected for calcium-containing beverages was tested. Ten commercially available beverages, five with and five without calcium supplementation, were tested in two phases. In the first phase, the pH, titratable acidity, and concentrations of calcium (total and ionic), phosphorus and fluoride, were analyzed. In the second phase, the ability of the test products to erode enamel was measured, at different time-points. Within the chemical properties tested, pH, calcium-ion concentration, and total calcium showed a strong correlation with enamel demineralization and enamel wear. Lower levels of enamel demineralization and wear were found for most of the calcium-containing beverages than for those without calcium. Calcium-ion content, as well as pH, were found to be good predictors of the erosive potential of the beverages tested. Generally, beverages supplemented with calcium had a reduced capacity to demineralize enamel.
牙釉质脱矿的发生和进展在其反应产物（如钙）存在的情况下可能会减少。因此，在本研究中，对含钙饮料具有较低侵蚀性潜力这一假设进行了测试。十种市售饮料，五种添加了钙，五种未添加钙，分两个阶段进行测试。在第一阶段，分析了pH值、可滴定酸度以及钙（总钙和离子钙）、磷和氟的浓度。在第二阶段，在不同时间点测量了测试产品侵蚀牙釉质的能力。在所测试的化学性质中，pH值、钙离子浓度和总钙与牙釉质脱矿和牙釉质磨损密切相关。与未含钙的饮料相比，大多数含钙饮料的牙釉质脱矿和磨损水平较低。发现钙离子含量以及pH值是所测试饮料侵蚀潜力的良好预测指标。一般来说，添加了钙的饮料使牙釉质脱矿的能力降低。
