Abstract
ABSTRACTObjectivesThe purpose of this study is to compare the mechanical properties (compressive strength (CS) and diametral tensile strength (DTS)) of four different restorative materials: conventional glass ionomer (Fuji IX), ClearFil AP-X, Filtex Z350-XT, and Cention N.Materials and methodsSpecimens (n = 80) were prepared from Fuji IX, ClearFil AP-X, Filtex Z350-XT, and Cention N for testing compressive strength and DTS.Statistical analysisResults obtained were subjected to one-way ANOVA and Tukey's post hoc test at significance (p < 0.001).ResultsThere were significant differences among restorative materials tested. ClearFil AP-X exhibits the highest mechanical properties (CS and DTS) and least values were obtained by the Fuji IX.ConclusionStrength is one of the most important criteria for the selection of a restorative material. Stronger materials better resist deformation and fracture, presenting more equitable stress distribution, greater probability, and greater stability of clinical success.How to cite this articleIftikhar N, Devashish, et al.

Highlights
Dental caries is an age-old disease which has been the blight of affliction in the oral cavity
From the earlier materials like silver amalgam to latest advances in composites, posterior restorative materials have been constantly evolving
It can be concluded that the mean compressive strength and diametral tensile strength (DTS) values of all the four restorative materials were significantly different because the composite materials available have a variation in composition and viscosity
Summary
Dental caries is an age-old disease which has been the blight of affliction in the oral cavity. It is one of the most widespread diseases in the population due to high ingestion of carbohydrates and lack of knowledge regarding proper oral hygiene methods. Once it occurs, restoring the carious lesions becomes compulsory. From the earlier materials like silver amalgam to latest advances in composites, posterior restorative materials have been constantly evolving. Each material used to restore posterior teeth has specific advantages and disadvantages and these should be suspiciously weighed before selecting a restorative material.[2]
