Microhardness of three glass-ionomer cements during setting and up to 15 days in vitro, and after 5 to 10 years in vivo

Conclusion: The microhardness of GICs was comparable to composite material after only 24 hours. In vivo the microhardness of GICs increased and after 10 years in vivo it was higher than that of the dentin. After 20 days the amount of fluorine was still high in Riva Self Cure and EQUIA Fil.
