The purpose of the current study was to evaluate the push out bond strength of a FRC post luted with self-adhesive resin cement after different surface treatment. A total of twenty four freshly extracted, human, caries free mandibular Premolars were used. Teeth were endodontically treated and decoronated to obtain a root of length 15 mm. Then were randomly assigned into four groups according to different surface treatment of fiber post as follows: G1: G2: G3: and G4: . Then the posts were cemented using self-adhesive resin cement. Following cementation of all samples, all specimens were stored in distilled water for 24h at 37, and then exposed to aging thermocycling (2000 cycles, ± 5C/55C). Then, push-out bond strength had been tested for the samples using universal testing machine. The recorded data were collected, tabulated and statistically analyzed
