Background and Objectives: The foremost goal of any clinician is providing the patient with a restoration which preserves the longevity of fixed partial dentures and regaining the lost function. In the oral environment, dental luting agents must withstand masticatory and parafunctional stresses. They should maintain their integrity while transferring stresses from crowns or fixed partial dentures to tooth structure. The purpose of this in vitro study was to compare and evaluate the diametral tensile strength of four commercially available luting cements. Method: A total of 120 samples were prepared of which 30 samples were prepared for Group A (GC gold label 1 luting and lining cement), 30 samples for Group B (Ivoclar Vivaglass cem), 30 specimens for Group C (3M ESPE Rely X Luting cement) and 30 specimens for Group D (Kerr Nexus RMGI). Pre formed polyethylene molds measuring 6.0±0.1 mm in diameter and 3.0±1. 0mm in thickness (ISO Standard 9917) are machined to prepare standardized cylindrical cement blocks. In these groups, based on duration of immersion in artificial saliva each group will be subdivided into three subgroups of 10 samples each.
