Retention between composite core and is still below the accepted level when compared with the retention between composite and dental structure. It has been suggested to treat chemical solvents to enhance mechanical connection with composite, and thus improve this retention Aim The study evaluate the effect of some chemical solutions to improve the mechanical connection between and composite. Materials and pieces of post (6 ±0.1 mm in length) were prepared ,75 glass fiber posts plus) and 75 quartz fiber posts Posts were horizontally embedded in acrylic resin with half of the post diameter exposed. The exposed surfaces were ground with separating silicon carbide discs under water , to ensure same smoothness. The specimens were randomly 5 subgroups representing different surface treatment techniques, including application of silane for 60 seconds(S) , etching with hydrogen peroxide 10% for 20 minutes(H1) , etching with hydrogen peroxide 20% for 10 minutes(H2), etching with chloride for 5 seconds(C1) and etching with chloride for 10 seconds(C2). Silane-treated specimens as controls. Bond (excite) was core was placed in a mold positioned upon the post specimens and polymerized for 20 seconds with (LED) polymerization unit. The specimens were stored in water at 37°C for 24 hours. Shear bond strength values of posts and composite resin cores were measured using a mechanical test machine were significant differences between the shear bond strength for (H2,C2) And (S)(P<0.05). C2 showed the highest bond strength values. There was no significant difference between glass and quartz groups (P>0.05). surface treatment of quartz and glass fiber posts with hydrogen peroxide 20% For 10 minutes and chloride for 10 seconds significantly enhanced the strength of the composite core. Application of chloride to the fiber post surfaces for 5 seconds and hydrogen peroxide 10% For 20 minutes were not effective in increasing the shear bond strength of the fiber post to composite core.
