Bonding of adhesive resin to intraradicular dentine: A review of the literature

Bonding to intraradicular dentine is widely practiced by modern dentists, both in general as well as specialist practices. Materials, such as resin-based root canal sealers and resin cements, are routinely used in endodontic treatment, like root canal obturation and luting fiber post for post and core restorations. Though bonding to intraradicular dentine in principle is the same as bonding to coronal dentine, there are several structural differences between coronal and intraradicular dentine substrates. Also, the consequences of pulpal necrosis and subsequent endodontic therapy could alter the intraradicular dentine substrate significantly, which would have an impact on intraradicular dentine bonding. Therefore, this comprehensive review was performed from the published literature retrieved from "Pubmed" database using specific keywords "root, "dentine", "resin", and "bonding". The relevant articles were selected after screening the title and abstracts. Further relevant articles included in this review were identified from the reference lists of the originally retrieved articles. In this review, we have narrated the various aspects of bonding to intraradicular root dentine. Successful bonding to intraradicular dentine depends on proper understanding of this unique bonding substrate. (C) 2015 Elsevier Ltd. All rights reserved.
