This in vitro study evaluated the effect of calcium glycerophosphate (CaGP) supplemented to soft drinks on bovine enamel erosion.
Four pH-cycles were performed, alternating demineralization by the beverage and remineralization in artificial saliva.
Mean wear (± SD, µm) was 7.91 ± 1.13, 7.39 ± 1.01, 7.50 ± 0.91 and 5.21 ± 1.08 for Coca-Cola® without CaGP or containing CaGP at 0.1, 1.0 or 2.0 mM, respectively, while no wear was detected for CaGP at 5.0 and 10.0 mM. Corresponding figures for Sprite Zero® without CaGP or containing CaGP at 0.1, 1.0, 2.0, 5.0 or 10.0 mM were 8.04 ± 1.30, 7.84 ± 0.71, 7.47 ± 0.80, 4.96 ± 0.81, 3.99 ± 0.10 and 1.87 ± 0.12, respectively.
Supplementation of both beverages with CaGP seems to be an alternative to reduce their erosive potential.
本体外研究评估了在软饮料中添加甘油磷酸钙（CaGP）对牛牙釉质腐蚀的影响。
进行了四个 pH 循环，交替用饮料进行脱矿质和在人工唾液中进行再矿化。
对于可口可乐®，无 CaGP 或分别含有 0.1、1.0 或 2.0mM CaGP 的情况下，平均磨损（±SD，µm）分别为 7.91 ± 1.13、7.39 ± 1.01、7.50 ± 0.91 和 5.21 ± 1.08，而 5.0 和 10.0mM CaGP 则未检测到磨损。对于雪碧零®，无 CaGP 或分别含有 0.1、1.0、2.0、5.0 或 10.0mM CaGP 的情况下，相应的磨损值分别为 8.04 ± 1.30、7.84 ± 0.71、7.47 ± 0.80、4.96 ± 0.81、3.99 ± 0.10 和 1.87 ± 0.12。
在两种饮料中添加 CaGP 似乎是减少其腐蚀性的一种替代方法。
