Abstract:

The stability of the hybrid layer formed by adhesive resin systems and dentin collagen fibrils is critical to the success of dentine restoration. The hydrolysis of dentin collagen fibrils by endogenous dentin proteases is responsible for the failure of dentin bonding. Studies have shown than chitosan and its derivatives, as an innovative biomaterial in dentin bonding, could enhance dentin bond strength and the durability of resin-dentin bond. This article reviewed the properties, mechanism and research progress of chitosan and its derivatives in dentin bonding.

Key words: chitosan, dentin bonding, biomodification
