Abstract
Recent studies have reported the incorporation of modifiers with conventional Glass Ionomer Cement (GIC) to enhance its physical properties. One such modification being the addition of Chitosan (CH). The present study was done to investigate the effect of modifying the liquid phase of two types of conventional GIC with 10% and 50% v/v CH in comparison to conventional GIC. The liquid of commercially available restorative GIC, GC Fuji IX andketac molar was modified with 10% and 50% v/v CH solution (Everest Biotech, Bengaluru). GIC powders were mixed with the unmodified and the CH-modified liquids at the desired powder/liquid ratio. Universal testing machine was used to determine the difference in compressive strength between the conventional and CH modified GIC liquid with GIC powder. Shipro-wilk test, one way anova test and post-hoc bonferroni was used to compare the compressive strength between CH modified GIC and unmodified GIC. Results showed that the modification with 10% v/v CH solution improved the physical property of both GICs but found insignificant in case of modification with 50% v/v CH solution. Compressive strength strength of CH modified GIC compared to conventional GIC.was found to be statistically significant. Modifying the liquid phase of a conventional GIC with 10% v/v CH significantly improves the physical property of GIC.
