SEM images of a representative specimen in the different toothpaste groups after demineralization of 8 h, remineralization (brushing with the appropriate toothpastes) and new demineralization of 2 h. Grey areas represent the intact enamel (enamel prism) and the black areas the defective enamel (corresponding to demineralization by the lactic acid).
