Abstract The aim of this study was to evaluate the push-out bond strength of two esthetic fiber posts namely; white and translucent, at different root levels (cervical, middle and apical third) by using different adhesive resin cementation techniques; total etch, self adhesive and self adhesive with acid etching. The dislodged posts were examined microscopically to evaluate the mode of failure. The investigated hypotheses were: 1. The retention of translucent fiber post would be higher than the white (non translucent) fiber post. 2. The use of acid etching before application of self adhesive resin cement may increase its bond strength. 3. The coronal third of the post may have higher bond strength followed by middle and apical thirds. |
