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. ?? 1986.
