    Author(s): Akram Altamimi M* and Manhal Majeed A

    Objectives: This study was designed to develop and assess the mechanical properties of an experimental bioactive glass fiber post by the reinforcement of bioactive cement. Study Design: An in vitro study. Material and Methods: surface treated unidirectional E-glass fiber were impregnated and implanted with a triple cure, self-adhesive ACTIVA Bioactive resin cement to fabricate an experimental bioactive glass fiber post using hand lay-up molding technique and clear cylindrical split mold with a 2mm diameter. Each specimen ensures 3min for self-cure setting, then light-cured for the 40s. The cylindrical shape post specimens (n=8) were prepared at room temperature for one day before subjected to fatigue test, A custom made three-point bending machine, loading at 90° angle and a frequency of 2 Hz was ..
