Abstract

Aim and objective: This study aimed to investigate and compare compressive strength and flexural strength of self-cured Cention N with dual-cured Cention N. Materials and methods: Cention N is mixed according to the proportions, as mentioned by the manufacturer. Dual cured samples are cured using a diode that emits blue light. Cylindrical plexiglass split mold of dimension 6 mm height, and 4 mm diameter used to fabricate samples for compressive strength. Compressive strength tested using Instron universal testing machine. Rectangular plexiglass split mold of dimension 25 mm length, 2 mm height, and 2 mm width were used to fabricate samples for flexural strength. Flexural strength tested using Instron universal testing machine. To compare the mean values independent t-test was used and the significance of the study was measured by calculating a p-value. Result: There is no statistically significant difference between compressive strength and flexural strength of self-cured Cention N with dual-cured Cention N. Conclusion: The type of polymerization does not affect flexural strength and compressive strength of Cention N. Clinical significance: Self-curing polymerization alone is sufficient for Cention N to achieve adequate compressive strength and flexural strength. So it can be inserted as a single layer on a prepared cavity and to fasten curing additional light curing can be used.
