Abstract

Glass ionomer cements (GICs) are restorative materials that have been commercially accessible for more than 50 years, and their extensive use is owing to their many benefits. However, GICs have several limitations. The poor mechanical qualities of GICs are the most significant drawbacks restricting their use.
This study aimed to examine the impact of incorporating moringa nano-powder (M/NP) and Chitosan (CH) solution into GIC on antimicrobial activity, compressive strength, and surface hardness. A significant improvement in antimicrobial capability was observed with dual alterations. The enhancement in the surface hardness was also a result of the synergistic effect of the dual modification. In contrast, there was a decrease in the compressive strength. In conclusion, the antibacterial and surface hardness characteristics of GIC were successfully boosted by adding moringa NP and Chitosan on the expense of compressive strength reduction.
This dual approach may offer one potential pathway for developing improved restorative materials.
