PUSH OUT BOND STRENGTH OF TWO DIFFERENT TYPES OF FIBRE POST USING SAME SELF ADHESIVE RESIN CEMENT.

Materials and Methods: Twenty human mandibular single-rooted second pre-molar teeth were decoronated, endodontically treated, post space prepared and divided into two groups ( n = 10); ) Group I: Everstick post (GC) and G-cem resin cement(GC) Group II: Tenax fibre post(Coltene) and G-cem Resin cement(GC). Each root was sectioned to get slices of 3 ? 0.1-mm thickness. Push-out tests were performed using a universal testing machine. To express bond strength in megapascals (Mpa), load value recorded in Newton (N) was divided by the area of the bonded interface. Results: The mean values of the push-out bond strength show that Group I had significantly higher values than Group II in middle third of the root . Conclusions: Within limitation of present study it can be concluded that customizable post shows good bond strength than prefabricated post. But means bond strength for both type of post is higher in cervcal region than middle and apical third.
