Abstract
Some fruit juices and carbonated acidic drinks, recognized as agents causing dental erosions, were analyzed for calcium, phosphate, fluoride and pH. Ionic activity/concentration products for hydroxyapatite and fluorapatite were calculated. It was found that all liquids analyzed were unsaturated with respect to both apatites, which explains their erosive effect.
摘要
对一些被认为是导致牙齿侵蚀的因素的果汁和碳酸酸性饮料进行了钙、磷、氟和pH值分析。计算了羟基磷灰石和氟磷灰石的离子活性/浓度乘积。结果发现，所有分析的液体对于这两种磷灰石都是不饱和的，这就解释了它们的侵蚀作用。
