The aim of study is to compare the shear bond strength of various primer/resin cement systems to monolithic Zirconium under different storage conditions. Materials and Methods: 30 disk specimens of monolithic zirconia (10 mm x 3mm) were prepared with CAD/CAM and polished with silicon carbide and bonding surface were sandblasted with aluminum oxide. Samples were divided into three groups according to the type of cement used: Duo Link Composite Luting Cement, Rely X Ultimate Adhesive Resin Cement, Panavia SA Cement Plus, and further divided into two group each based on the storage conditions into Short Term Storage and Long Term Storage. The specimen were embedded in acrylic mould and SBS test were performed. The data were analysed by non-parametric Kruskal Wallis and Mann-Whitney U. significance was set at P<0.05. Result: The highest and lowest SBS values were obtained by kurary system (16.78) and Bisco (8.22) respectively in short term storage. Similarly in long term storage group Kurary (13.7) has highest and bisco (5.2) has lowest SBS value. Conclusion: Long term storage conditions decreases the Shear bond strength of monolithic zirconia to all resin cement systems. The highest bond strength was obtained when both the primer and resin cement contain MDP in their composition.
