Abstrakt		NMR microscopy of water penetration into glass-ionomer cements was performed. Chemically and light cured samples were studied. A slightly higher diffusion rate into chemically cured samples was demonstrated. The distinction in internal structure of the two materials is clearly visible after few days when the water has reached the centers of both samples. T2 mapping, self-diffusion constant measurement and magnetization transfer experiment were additionally performed to confirm that variations in pore size through the sample are responsible for signal inhomogeneities of chemically cured samples. Inferior mechanical properties of these materials are in accordance with NMR data.
