Abstract
Aim: The push out bond strength of a fiber post system was evaluated and compared using a self-etch resin cement and a total-etch resin cement. Materials and method: In this in-vitro study 30 maxillary central incisors were decoronated from the CEJ. Root canal preparation and obturation were done and post space was prepared using peeso reamers (Size #3). Samples were randomly divided into 2 groups (15 samples each). Group A consisted of posts luted using self-etch resin cement (RelyX U200; 3M ESPE), and Group B consisted of posts luted using total-etch resin cement (Variolink N Intro Pack; Ivoclar Vivadent). The samples were then sectioned into 3 parts – Coronal, Middle and Apical; and subjected to push out bond strength testing under a Universal Testing Machine. Results: There was no significant difference seen in the push out bond strength of the fiber post system (RelyX U200:84.353, Variolink N Intro Pack: 28.741); whereas, significant difference was seen at different root levels. Conclusion: The push-out bond strength of both the cement was non-significant. When the push-out bond strength was compared at various root levels; the coronal segment exhibited higher push-out bond strength, followed by the middle segment and the lowest was shown by the apical segment.
