Abstract:
Aim : To compare regional bond strength in different thirds of the root canal, among glass fiber‐reinforced (FRC) endodontic posts luted with different cements, using the push‐out test. Material and Methods: Sixty extracted human anterior teeth were endodontically treated with gutta‐percha and AH Plus® sealer. The crown portion was removed, and a dowel space was prepared. Prepared teeth were randomly assigned to one of six groups ( n = 10) for luting glass FRC Postec posts, with one of the six cement systems (Ketac™ Cem Aplicap™, Relyx™ Unicem Aplicap, Variolink® II/Excite® DCS, Panavia™ F/ED Primer, C & B™ cement/All‐Bond® 2, and Multilink®/Multilink® Primer A/B), using an alignment technique. Specimens were embedded in resin, and each root was sectioned into six 1‐mm thick serial slices. A push‐out test was performed to measure regional bond strengths and to identify the type of failure. Results : The highest bond strength values were found in the cervical third and the lowest in the apical third. Highest values were obtained using Variolink II, Panavia F®, and Multilink® resin cements followed by C & B™ resin cement and Relyx Unicem® ionomer resin cement; Ketac‐cem® ionomer cement showed the lowest value. Conclusion : Highest bond strength values were obtained in the cervical third and with resin cements. © 2007 Wiley Periodicals, Inc. J Biomed Mater Res Part B: Appl Biomater, 2007
