Fig. 1From: Remineralization and protection from demineralization: effects of a hydroxyapatite-containing, a fluoride-containing and a fluoride- and hydroxyapatite-free toothpaste on human enamel in vitroSystematic drawing of how the respective enamel surfaces on a tooth were demineralized and remineralized with the corresponding toothpastes in order to obtain the individual samples for SEM evaluation. (large image: cross-section with surfaces S0—S4, small image: schematic view from occlusal with vertical cuts to obtain the SEM specimens.)Back to article page
