Comparative Evaluation of Cention with Glass Ionomer Cement, Composite Resins and Silver Amalgam with Respect to Mechanical Strength: An in-Vitro Study

Introduction: Numerous direct filling materials are available to the modern dental practice from amalgams,\r\nGIC to modern bulk fill composites. Cention is an “alkasite” restorative. Alkasite refers to a new category\r\nof filling material, which like compomer or ormocer materials is essentially a subgroup of the composite\r\nmaterial class. This new category utilizes an alkaline filler, capable of releasing acid-neutralizing ions. It is\r\na tooth-colored, basic filling material for direct restorations. It is self-curing with optional additional light\u0002\r\ncuring. It is radiopaque, and releases fluoride, calcium and hydroxide ions. As a dual-cured material it can be\r\nused as a full volume (bulk) replacement material. Hence the Aim of the study was to compare the Alkasite\r\n(Cention N) with Silver amalgam, GIC and Composite to evaluate the Compressive strength \u0026 diametral\r\ntensile strength.\r\nMaterials and Method: Split molds of dimension 6 [height] x4 [diameter] was used to fabricate 15 samples\r\nof each material for testing the compressive strength and for tensile strength. And subjected under Universal\r\nInstron testing machine connected to a load measuring cell, to recorded load applied to the samples at a\r\ncrosshead speed of 0.75 ± 0.25 mm/min till the samples fracture.\r\nResults: Composite and Cention N showed significantly higher strength than Silver Amalgam and Glass\r\nionomer cement.\r\nConclusion: Within the limitation of this study, it can be concluded that Cention N can be used as a superior\r\nalternative when compared with Silver Amalgam and Glass ionomer cement.
