Aim: To evaluate and compare the mechanical properties such as Compressive strength, Flexural strength and Knoop Microhardness of Cention-N and Type IX GIC using Universal Testing Machine and Micro Hardness Tester.
Methodology: Test specimens were made using custom made plexi glass moulds with different dimensions according to ISO Standard specification, ISO 9917 and were grouped as Group-I and Group-II. Group-I consisted of Cention-N specimens and Group-II consisted of Type IX GIC specimens with specific dimensions. After the test specimen fabrication, they were stored in distilled water for 24 hours prior to the respective mechanical testing using Universal Testing Machine and Micro Hardness Tester.
Results: Cention-N (Group-I) exhibited superior mechanical properties when compared to Type IX GIC (Group-II).
