150-250μm longitudinal slices were taken of each sample. Re-mineralization was assessed according to bi-refringence observed after applying Thoulet solution 1.47 IR. Assessment was conducted under polarized light in a photo-microscope. At 15 days, a mean of 0.444 ± 0.527 was observed.
Se observaron cortes longitudinales de 150-250 µm de cada muestra y se valoró la remineralización, de acuerdo a la birrefringencia observada después de aplicarles solución de Thoulet 1.47 IR bajo luz polarizada en un fotomicroscopio.
