Online published on 31 March, 2020. Abstract Background and Objectives Dental caries is one of the most common problem encountered in pediatric patients. Despite modern advances in prevention of dental caries, many teeth are still lost prematurely leading to loss of function, esthetics, arch length and arch symmetry. Various restorative materials are available for the treatment of dental caries. Physical and mechanical tests were applied to analyze the structural designs of restorative materials. Various researches have been carried out in search of an ideal restorative material. Hence, the present in-vitro study was done to evaluate and compare the mechanical properties(compressive strength, flexural strength and knoop microhardness) of Ceramic Reinforced Glass Ionomer Cement (Amalgomer CR) and Type IX GIC. Results The study showed a statistically significant difference in the compressive strength, flexural strength and knoop microhardness of ceramic reinforced glass ionomer cement (Amalgomer CR) and is superior when compared to Type IX GIC. Conclusion The study concluded that the mechanical properties (compressive strength, flexural strength and knoop microhardness) of ceramic reinforced glass ionomer cement (Amalgomer CR) is superior to Type IX GIC. Top Keywords Compressive strength, Flexural strength, Knoop Microhardness, Glass ionomer cement, Amalgomer CR. Top |
