Push out bond strength test was perfomed on<span class="Apple-converted-space">  </span>two types of cement: Kuraray Panavia (Japan) and Gradia Core (GC Tokyo Japan) in combination with two types of fiber posts: Edelweiss post (Edelweiss Dentistry Products GmbH, Wolfurt, Austria) and GC Fiber Post (GC Gradia Core Tokyo Japan).</p> <p class="p1"><strong>Results</strong><span class="Apple-converted-space">  </span>According to the results of this study, the GC Post / Gradia Core group recorded push-out forces significantly higher than those of the groups in which the new post was used (p <0.05).</p> <p class="p1"><strong>Conclusion</strong> Within the limits of this <em>in vitro</em> study, it can be concluded that the highest values of adhesive strength in the push-out test were achieved by GC post/Gradia Core GC. Regarding the area of root that can produce the best push out bond strength, it clearly resulted that the coronal third of the root was the best substrate to lute posts.</p>}, number={3}, journal={Journal of Osseointegration}, author={Pennacchio, M.
