Effect of Endodontic Sealers on Push-Out Bond Strength of Cemented Fiber Posts
Author(s): Ziad N AL-Dwairi
OBJECTIVE: The purpose of this study was to compare the effect of eugenol-based and resin-based endodontic sealers on the pushout bond strengths of prefabricated fiber posts luted with different resin cements.METHOD AND MATERIALS: Ninety prefabricated fiber posts were luted into extracted singlerooted teeth with one of three resin cements (Variolink II, ParaCore, or Rely X Unicem). Each group was subdivided into three groups with 10 teeth each. The first two groups were obturated with gutta percha and one of two eugenol-based endodontic sealers (Endofil or TubliSeal) each. The third group was obturated with gutta percha and (AH26) resin-based root canal sealer. Push-out tests were performed in a universal testing machine by applying a load speed at 0.5 mm/ min by using a 1-mm-diameter metallic plunger which induced a load in an apical to coronal direction. The maximum value for post d.. View More»
