Objective: This study aimed to evaluate the effect of adding chitosan (CS) to conventional glass ionomer cement (GIC) on protein release and its cytotoxicity.
Methods: Bovine serum albumin (BSA) was used as the released protein from two glass ionomer formulations. One (GIC+BSA) contained fluoro-aluminosilicate glass mixed with BSA, and another (GIC:CS+BSA) used a similar glass and BSA with 20% chitosan.
