Objectives: How silver diamine fluoride affected the immediate and prolonged adhesive resin composite's resistance to sound dentin of permanent premolars. Procedures: Three groups were identified (total number=30). The manufacturer's recommendations were followed while applying adhesive resin to the dentin surfaces in Group A after they had been etched. In Group B and C, dentin surfaces were treated with silver diamine fluoride and 0.05% NaF respectively. Then etched and bonded as for the control group. Then resin composite build-ups were created. Following this, each group was divided into two subgroups (for each group n=5), subgroup 1 underwent a shear bond strength test by universal test machine after 24 hrs, subgroups 2 the test was done after thermocycling process (300 cycles). The mode of failure was also examined. Results: The type of dentin surface treated with SDF solution was significantly affect shear bond strength (p=0.000) for both periods (immediate and prolonged). However, there were no significant difference between NaF group and control group on shear bond strength (p<0.05) in immediate and prolong periods. On other hand there were statistically no significant differences between immediate and prolonged shear bond strength in SDF group (p=0.850),


 NaF group (p=0.637) and control group(p=0.794) When dentin surfaces were treated with silver diamine fluoride , there were more adhesive failures  not as 0.05% NaF and control group which showed  more mixed failures. Conclusion: silver diamine fluoride significantly reduced bond strength of etch and rinse adhesive system. Pretreatment with NaF maintained the shear bond strength of the adhesive to dentin after 300 thermal cycles.
