Comparative Evaluation of Flexural Strength and Modulus of Elasticity of Three Adhesive Luting Cements at Different Time Intervals under Oral Simulated Conditions: An In Vitro Study

Abstract Aim The purpose of this study was to compare and evaluate the flexural strength modulus elasticity three adhesive luting cements as a function specimen age, effect storage media, curing through porcelain. Materials Methods Twenty samples fabricated for self-cure resin-modified glass ionomer cement (GIC; RelyX Luting 2, 3M ESPE, United States) were classified group 1, whereas 40 two dual-cure resin (20 each), Universal Resin Cement (Ammdent, Italy) Maxcem Elite (Kerr Australia Pty. Ltd.), groups 2 3, respectively. photo-activated using light cure unit with an intensity 550 mW/cm2 in nine overlapping sections 20 seconds per section on both sides. A total 60 each group) tested universal testing machine GIC cements, determine influence specimens artificial saliva at 37°C 24 hours porcelain disk mm thickness these properties. Results overall mean less than cements. values reduced when after saliva, increase seen properties showed better all parameters. Conclusion When comparing compared GIC, which indicates their use cementation fixed restorations.
