Abstract

Background & Aim: Despite several advantages associated with prefabricated translucent glass-fiber posts, the coronal portion of these posts must be cut to allow their use in various clinical situations. The aim of this study was to investigate the effect of fiber post cutting on the bond strength of translucent and opaque fiber posts in different root sections.Materials and methods: In this study 60 sound mandibular premolar teeth were randomly devided in to 6 groups (n=10). Teeth were decoronated and endodontically treated. Post spaces were prepared.In 30 roots (groups 1, 2, 3) translucent posts while in another 30 roots (groups 4, 5, 6) opaque posts were cemented using self-adhesive RESIN CEMENT. The posts were cut prior to cementation (groups 1, 4), immediately after luting (groups 2, 5) or after building up the core (groups 3, 6). Using low speed saw, 1mm-thickness coronal, middle and apical sections were obtained from each sample. Then they were subjected to push-out test. Data were collected and statistically analyzed using three-way ANOVA and Tukey post hoc test (a=0.05).Results: The push-out bond strength when fiberpost cutting was done befor cementation was significantly higher than bond strength for post cutting immediately after cementation (p=0.004). Also the mean bond strength of translucent posts was higher than opaque posts (p=0.025). But root section did not show any effect on bond strength (p=0.621).Conclusion: Post translucency increased the push-out bond strength of dual-polymerized self adhesive resin luting agents, however the bond strength was reduced when cutting was done “immediately after cementation” of posts.
