Comparison of sorption, solubility, and flexural strength of four resin luting cements in three different media: An in vitro study

Background: The clinical success and durability of luting cements are determined by structural integrity and dimensional stability. Sorption and solubility resin luting cements in food-simulating solutions has not been studied sufficiently. Aims and Objectives: To compare the sorption, solubility, and flexural strength of resin luting cements in artificial saliva, ethanol:water (1:1) and distilled water at 37°C. Materials and Methods: Four commercially available resin cements were selected. Diskand rectangular-shaped samples will be prepared according to ISO standard-4049. Out of 160 specimens, 120 disc-shaped specimens will be subjected to sorption and solubility analysis. 40 rectangular-shaped specimens will be subjected for flexural strength analysis. Results: The result of the study clearly depicted that highest water sorption was observed for GC Fuji Cem in distilled water and artificial saliva media. For Composite Ionomer highest sorption was observed in ethanol:water medium. Panavia F showed least sorption in all three media. GC Fuji Cem exhibited more solubility in artificial saliva and ethanol:water (1:1) media, Composite Ionomer showed more solubility in distilled water medium. Secure luting agent showed least solubility in all three media. Highest flexural strength was observed by Panavia F and least by Tokeyoma Ionomer. Conclusion: Within the limitation of this study resin luting (Panavia F and Secure) agents showed least sorption, solubility, and highest flexural strength than compared to resin reinforced glass ionomer cement (GC Fuji Cem and Tokeyoma Ionomer).
