Recent Advances in Adhesive Bonding: The Role of Biomolecules, Nanocompounds, and Bonding Strategies in Enhancing Resin Bonding to Dental Substrates

Abstract

Purpose of review

To present an overview on the main agents (i.e. biomolecules and nanocompounds) and/or strategies currently available to amplify or stabilize resin-dentin bonding.

Recent findings

According to studies retrieved for full-text reading (2014–2017), there are currently six major strategies available to overcome resin-dentin bond degradation: (1) use of collagen crosslinking agents, which may form stable covalent bonds with collagen fibrils, thus strengthening the hybrid layer; (2) use of antioxidants, which may allow further polymerization reactions over time; (3) use of protease inhibitors, which may inhibit or inactivate metalloproteinases; (4) modification of the bonding procedure, which may be performed by using the ethanol-wet bonding (EWB) technique or by applying an additional adhesive (hydrophobic) coating, thereby strengthening the hybrid layer; (5) laser treatment of the substrate prior to bonding, which may cause specific topographic changes in the surface of dental substrates, increasing bonding efficacy; and (6) reinforcement of the resin matrix with inorganic fillers and/or remineralizing agents, which may positively enhance physicomechanical properties of the hybrid layer.

Summary

With the present review, we contributed to the better understanding of adhesion concepts and mechanisms of resin-dentin bond degradation, showing the current prospects available to solve that problematic. In addition, adhesively-bonded restorations may be benefited by the use of some biomolecules, nanocompounds or alternative bonding strategies in order to minimize bond strength degradation.
