Introduction: Glass ionomer cements have many advantages as restorative materials: adhesion to the tooth structure, fluoride releasing capacity, biocompatibility. However, their mechanical properties are not desirable they should be for conventional glass ionomers, questioning use a material. Aim: The aim of this study was compare compressive strength two encapsulated commercial – (Riva Self Cure) and resin-modified cement Light Cure). Materials methods: Six six specimens were prepared kept in 10ml deionised water at 37°C 24 hours 28 days. (after days) loaded an Instron testing machine compression until failure. A crosshead speed 1mm/min load cell 30kN used conduct test. Results: Resin-modified showed greater values after days than ionomers. both increased from days, with ionomers showing change over time period. Conclusion: This suggests that cross-linked polymer matrices higher strengths gel network formed by acid-base reactions
