N2  - Objective: This study was performed to evaluate bond strength of a new self-etch self-adhesive / flowable composite in comparison with one step-self etch adhesive / flowable composite and two step total-etch adhesive / flowable composite. Materials and methods: Shear bond strength of the investigated material to middle dentin of primary teeth was evaluated after 24 hours. A total of  thirty caries free , freshly extracted primary molar were utilized in this study. Teeth were divided into three groups according the material used (n = 10 per group). Buccal surface of acrylic embedded molars were ground into flat dentin surface ,to which material were applied according to manufacture instruction composite was applied split Teflon plate to form  cylinders (2mmin diameter and 2mm in height)were constructed on the buccal surface of specimens to which shear-force was applied to a failure using A universal testing machine at a crosshead speed, 0.5mm/minute. After the test procedure, fractured surfaces were observed using a stereomicroscope (50X) to determine the failure mode. Representative sample per each group were investigated resin /dentin interface  under scanning electron microscope
