Comparative Evaluation of Compressive Strength and Flexural Strength of Self-cured Cention N with Dual-cured Cention N: An In Vitro Study

Abstract

A bstract 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. C linical S ignificance 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 Fousiya Ks, Balagopal VR, Suresh KJ, et al.

Cention-N: A Review

“…Compressive strength: Compressive strength is defined as the maximum compressive stress that a plastic specimen can withstand until it ruptures or deforms by a certain percentage. Mean compressive strength value of 151.40 MPa for selfcured Cention N and 157 MPa for dual-cured Cention N [21].…”
