Slices of enamel were demineralized in weak acid solutions at pH 5. The solutions were analysed for Ca, P, Na and Mg. A substantial increase of the Ca/P ratio in the solution after about 6 h of demineralization was ascribed to brushite formation. The ratios of liberated Ca/Na, P/Na, Ca/Mg and P/Mg were always lower than the correspondent ratios in sound enamel. It was concluded that precipitation of brushite, and a preferential dissolution of Na and Mg compounds from the enamel both play a role in the dissolution-precipitation reactions in dental enamel during acid attack.
将牙釉质切片置于pH值为5的弱酸溶液中进行脱矿。对溶液中的钙、磷、钠和镁进行分析。脱矿约6小时后，溶液中钙/磷比值大幅增加，这归因于磷酸二钙的形成。释放的钙/钠、磷/钠、钙/镁和磷/镁的比值始终低于健康牙釉质中的相应比值。得出的结论是，磷酸二钙的沉淀以及牙釉质中钠和镁化合物的优先溶解在酸蚀过程中牙釉质的溶解-沉淀反应中均起作用。
