Evaluation and comparison of flexural strength of Cention N with resin-modified glass-ionomer cement and composite - An in vitro study.

Aim: The aim of this study was to evaluate and compare the flexural strength of Cention N with resin-modified glass-ionomer cement and nanohybrid composite. Materials and Methods: Samples were prepared by filling the stainless steel mold of dimension 2 mm × 2 mm × 25 mm with cement/composite immediately after mixing. Excess flash if any was removed by abrading it with abrasive paper. Then, the specimens were subjected to flexural strength measurement using universal testing machine. The results were then tabulated and statistically analyzed using one-way ANOVA followed by Tukey's multiple post hoc test. Results: The average flexural strength of NT Premium, Vitremer, and Cention N was 90.39 MPa, 46.59 MPa, and 62.88 MPa, respectively. There was a statistically significant difference between NT Premium and Cention N and NT Premium and Vitremer with P = 0.0002 and 0.0001, respectively. Significance: The flexural strength study can help us to choose a material for restoring Class V lesions and can also confirm whether Cention N, a new material, be a definite replacement for amalgam. Conclusion: Cention N has proved to be a better material and can be a replacement for amagam and GIC.
