| Abstract | ||||
| Purpose: The aim of the investigation was to evaluate effect of water storage on microshear bond strength using two adhesive resin systems. Material and methods: A total of sixteen teeth were divided into two groups according to the adhesive system used; Group 1: 3M Single Bond Universal (SBU) and Group 2: G-Premio Bond (GP). Each group was further subdivided into two subgroups; Subgroup A which was stored immersed for 24 hours in distilled water and Subgroup B stored for 2 months. Four micro-cylinders of resin composite (3M ESPE Filtek TM Z250 XT), were placed on the conditioned dentine surfaces. Bonding performance was assessed via microshear bond strength test (mSBS) using universal testing machine after 24 h and 2 months’ water storage. The data was registered using computer software in MPa. Results: The results revealed that the highest bond strength values were revealed in samples bonded with 3M Single Bond Universal, followed by samples bonded by G-Premio Bond after 24h water storage. After 2 months’ water storage, the samples bonded by G-Premio Bond showed higher values, but with no statistical significant difference. Conclusion: The water aging resulted in a significant decline in the microshear bond strength values. | ||||
