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: -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. How to cite this article: Study. Int J Clin Pediatr Dent 2022;15(2):210-214.
