Abstract

Aim: The aim of this study is to assess the bond strength and the mode of failure of a glass fibre-post luted using two different adhesives. Materials and methods: Fourty human permanent maxillary central incisors were decoronated, endodontically treated, divided into two groups (n = 20), after post space preparation; group I: clear post RO (Dispodent) and Variolink II (Ivoclar Vivadent); group II: clear post RO (Dispodent) and Multilink N(Ivoclar Vivadent). The roots were sectioned to a thickness of 2 ± 0.5. Universal testing machine was used for testing the push-out bond strength. By dividing bond value recorded in Newton (N) and the area of bonded interface, the bond strength was derived in megapascal (MPa). After evaluating the push-out strength, the samples were analysed using a stereomicroscope to check the mode of failure. Results: Group I showed significantly higher push-out bond strength than Group II. Adhesive bond failure between dentin and luting cement and post and was most commonly observed Conclusion: Group I utilising Variolink II as luting cement which employs total etch technique had higher mean push-out bond strength. Bond failure between cement-dentin interface followed by post cement interface was observed as the most common type of failure, impling difficulty in a post cement dentin interface bond. Clinical significance: The success of endodontic treatment depends not only on elimination of pulpal/periradicular pathology but also on post-endodontic management involving the maintenance of extensively damaged tooth in a functional state. In an attempt to prevent the occurance of catastrophic events like vertical root fracture associated with metal posts, fibre reinforced glass posts were introduced, which mimic dentin in relation to elastic modulus. In addition to this, improvements made in adhesive techniques further led to the popularity of these fibre reinforced posts.
