Abstract: In vital teeth, pulpal pressure causes the continuous outward flow of intrinsic water through the dentinal tubules to the bonding interface,which damages the integrity of the adhesive-dentin bonding interface, and then reduces the bonding strength and affects the durability of adhesive repair.This article contains a brief review of the effects of the outward flow of intrinsic water through the dentinal tubules on the bonding interface, nano-microleakage and bonding strength of different bonding systems.Moreover, this article discusses the measures to reduce the detrimental effects of outward flow of intrinsic water through the dentinal tubules on the bonding interface.

Key words: intrinsic water, dentin bonding systems, bond strength
