A comparative evaluation of compressive strength of Cention N with glass Ionomer cement: An in-vitro study

Abstract

Aim: The aim of the present study was to evaluate and compare the compressive strength of Cention N with Glass Ionomer cement as a restorative material. Materials and Methods: Customised cylindrical moulds of dimension 6±1mm (height) × 4±1mm (diameter) were used to fabricate 10 samples each of Cention N (Ivoclar Vivadent) and Glass Ionomer Cement (GC IX High strength Posterior restoration). Then, samples were tested for evaluation of compressive strength using Universal Testing Machine (UTM). This was connected to a load measuring cell, which continuously recorded the load applied to the samples at a crosshead speed of 0.75 ± 0.25 mm per 1 minute till the samples fractured.Results: The values were recorded and subjected to statistical analysis for comparison of compressive strength (MPa) between the two materials using SPSS software. In order to compare the means of two materials, Independent T-Test was used. The results of the study showed that Cention N had high compressive strength than GIC Type IX. Conclusion: Within the limitation of this study, it can be concluded that Cention N can be used as a superior alternative to GIC Type IX for restoration of posterior teeth since its compressive strength was found to be significantly higher. However, long term clinical studies are required to draw any substantial conclusion.
